K'89 Eleventh International Trade Fair - plastics and rubber.

K'89 ELEVENTH INTERNATIONAL TRADE FAIR--PLASTICS AND RUBBER

K'89, heading for a new record, will comprise over 2100 exhibitors from 40 countries. The 11th International Trade Fair for Rubber and Plastic, to be held in Dusseldorf, West Germany, from November 2 to 9, will be spread over 16 halls with a total exhibition space of 174,000 square meters.

The largest national representation will be from the host country, with 1046 exhibitors as of press time. Among the foreign exhibitors, which account for about 50% of the total, Italy leads with 299, followed by France, with 94; Britain, 82; Switzerland, 80; the Netherlands, 76; and the U.S.A., 69.

North and South America will be represented by 110 exhibitors; about 70 will be from Asia. Companies from 19 countries will be presenting their products at joint stands. K'89's fully booked exhibition space has had to be supplemented by a large new exhibit area, to house mechanical engineering and processing stands, the size of one and a half football fields.

Attendance is expected to surpass the record of 220,000 trade visitors who came to Dusseldorf for K'86. Some 50% of that total represented attendees from outside of West Germany.

In addition to plastic raw materials and the full range of state-of-the-art injection, blow, and extrusion and foam molding machinery, K'89 also will showcase the latest designs of calendering, welding, and finishing equipment. The huge triennial show thus provides outstanding opportunities to take advantage of the latest developments in plastic materials and processing technology, and to gain perspective on things to come. Visitors to K'89 will be able to tap the expertise of technical and marketing people across the broad spectrum of the plastics industry.

CONTINUING DEVELOPMENT

The large exhibit of the Battenfeld Group will accent the continuing development of high quality machines that focus on processing flexibility. One demonstration will be Battenfeld GmbH's Type BM-T 2x9000/2x6300 Unilog 8000 two-component injection molding machine with a two-channel system and a total clamping force of 18,000 kN. Battenfeld says the universal machine is ideal for economical testing of new materials, especially engineering plastics.

Processing capabilities at the exhibit will include conventional injection and sandwich molding; use of the Airmold method for making hollow-shaped parts; and the Multifoam solid skin/foamed core and two-color injection molding processes. Two equal injection units can operate together or separately by means of a special two-channel nozzle, independently operated by hydraulics shutoff mechanisms.

Battenfeld GmbH also will exhibit a new production cell featuring two Type BA-T 1600/630 Unilog 4000 hydraulically operated injection molding machines in line with a four-station mold magazine. A mold changer that runs alongside the machines conveys the preheated molds in an integrated system that includes two robots and precision weighing units.

Battenfeld Austria, applying the CD (Compact Design) module technology, will facilitate designing "specials" to meet specific processing requirements. Precision building blocks for different applications will be available from among a broad series of standardized machine components.

The company also will show multiple production machines linked to a host computer on the factory management principle, and equipped with automatic mold, raw material, screw/cylinder, robot gipper, and program changeover.

A four-station in-line automatic compression molding machine, the BRE 600, to be exhibited by Battenfeld Berges, increases the versatility of thermoset processing. Different small-and medium-sized thermoset moldings can be manufactured "just in time" for downstream finishing, or the machine can be readily converted for mass production of identical parts on all four stations. The four stations are operated from a central drive using proportional hydraulics, with the operating sequences of the individual stations controlled by a Unilog 4000 system.

A new generation of Battenfeld Fischer BFB1 Series blowmolding machines, with two double stations for small-and medium-capacity container production, also will be displayed by the company, as well as self-contained designs for manufacturing extremely large blowmolded parts.

A newly developed laboratory extrusion machine for pelletizing engineering plastics; a profile extrusion line and an extrusion line for manufacture of pipe; and equipment for producing coextruded sheet, controlled by the Extrol 6032 microcomputer-based system, will be among the other new designs at the diverse Battenfeld K'89 stand.

COMPUTER TECHNOLOGY

Cincinnati Milacron's stand at K'89 will reflect the company's commitment to use of CAD/CAM, finite-element analysis, solid modeling, and flexible manufacturing system techniques in designing and manufacturing cost-effective plastics machinery for a wide range of sophisticated engineering and high-speed applications. Vista toggle models VT 100,200, and 275, each with interchangeable barrel/screw combinations for process versatility, will be demonstrated at the company's Technology Center. Closed-loop clamp, injection velocity, and pressure control; multiprocessors with diagnostics; energy-efficient variable-volume pumps with proportional hydraulics; adaptive shot control; and precise twin-cylinder injection units are among the features of the machine series.

Cincinnati Milacron also is expanding its Vista line to include hydraulic clamp injection molding machines, featuring simple operator/machine setter interface and reliable repeater performance. Many of the features of the toggle series are included, including six interchangeable barrel/screw combinations and full proportional hydraulics.

The VH series is being introduced in four clamp sizes, from 450 to 775 kN, with the expectation that five additional clamp sizes between 1000 and 3500 kN will be offered over the next year. Finite-element analysis was implemented to ensure maximum strength-to-deflection ratios in rigid cast platens and clamp cylinders. The low-profile design includes a shuttle tank reservoir mounted at the prefill for fast buildup of clamp tonnage.

The Vista toggle and hydraulic machines use Cincinnati Milacron's CAMAC family of multiprocessor VLC, VEL, and XTL controls, which will be displayed at K'89. Standard features include easily understood direct access menus, multistage clamp speed profile and closed-loop clamp position control, process monitors that ensure that molded parts remain within tolerance, and internal storage for up to 40 different mold settings.

The VLC control also incorporates a liquid crystal display terminal. The VEL control being introduced adds the advantage of a graphic display of injection pressure and velocity curves on its electrolu-minescent screen. It also can communicate with ancillary equipment.

The XTL control, the most advanced, offers three screens to set up the entire machine, production monitors, and a high-resolution graphics package. An on-board statistical process control monitors processing conditions and supplies a printed documentation of the quality of molded products.

At the Technology Center, Cincinnati Milacron's VT 100, with VEL control, will be molding high-impact polystyrene window spacers in an eight-cavity mold. The VT 200, with XTL control, will mold high-impact polystyrene video cassettes; and the VH 450, also with XTL control, will be molding a single-cavity computer top of ABS. The XTL control will regulate all of the ancillary equipment in the production cell. Four control simulators will help visitors become familiar with the systems' capabilities.

Visitors to K'89 also will be able to see Cincinnati Milacron's second generation of the accurate and power efficient ACT all-electric injection molding machines. The oil-free D Series, with linear movement repeatability to 0.01 mm, shot weight accuracy to 0.05%, noise level at less than 65 dbA, and power consumption down to 25% of conventional machines, also offers increased plasticizing, injection rates, and clamp speeds.

The machine sizes currently range from 30 to 300 kN. At K'89, and ACT 30 will mold a precision electrical connector out of polybutylene terephthalate, and an ACT 300 will mold a Fresnel lens from an acrylic material.

In addition to displaying its high-output-rate CMS single-screw extruders, Cincinnati Milacron will show the new CMT 68 and 80 models of its twin-screw extruder series. The machines promise increased output rates and enable use of different formulations over a wide processing range. The CMT 68 has microprocessor control and a PVC pipe tool featuring a thermally centered die set. The CMT 80 includes a Cimicron CMC-S control system particularly suited for extension to a fully automated line. Also on display will be the CMT 35 for profile and small-diameter pipe extrusion and the CMT 45 with a tool to produce coextruded rigid PVC foam profile.

AUTOMATION AND ON-LINE QC

Werner & Pfleiderer will unveil its advanced line of ZSK polymer processing extruders. In actual process demonstrations of two twin-screw laboratory/pilot scale models, the ZSK 40 and 25, W&P will show how its extruder systems measure, document, and detect and automatically compensate for process deviations, maintaining rigid quality control within small tolerances of the setpoint. Demonstrations of the capabilities of the "intelligent" ZSK will feature on-line rheometry, infrared spectroscopy, and color measurement and adjustment.

For compounding and coloring of reinforced and nonreinforced polymers, a ZSK 40 with axial throttle, coupled with an EPC 11 microprocessor-based control system, will demonstrate advances in on-line color measurement and adjustment.

W&P will show its newly developed throttle valve devices, which permit rapid change of the ZSK's screw characteristics in the various process zones, without reconfiguration.

Also on display will be ZSK and gear pump combinations, which reduce material temperature and specific energy input during compounding of shear-and heat-sensitive polymers. A two-stage processing line consisting of a ZSK 58 and a gear pump will be shown.

A new, environmentally safe and energy-efficient devolatilization technique for monomers and solvents, to the lowest ppm, will be presented, including the devolatilization of high-solvent-content polymers (50% or more) on large production machines such as the ZSK 240 and 300.

W&P will also demonstrate proprietary processes developed for continuous polymerization, polyaddition, and polycondensation of various polymers on ZSK reactors, starting with monomers and prepolymers. Examples are mass polymerization of polyurethane or acetals.

MULTI-PRODUCT DISPLAY

About 300 exhibits at Bayer AG's stand will demonstrate new products and applications for its polymer materials. The Plastics Group will show further developments of Apec, a material from the polycarbonate family that is resistant to heat distortion up to 238[degrees] C; electrically conductive and antistatic Tedur polyphenylene sulfide compounds; Polystal liquid crystal polymer tape, which is used to reinforce and lighten, for example, cross-country racing skis; optical fibers based on Makrolon polycarbonate; and Novodur low-gloss ABS matte grades for extrusion and injection molding. Finished products also will document the wide range of applications of the company's Baytec polyurethane elastomer and Bayflex 150 polyurea for reaction injection molding, notably for the automotive industry.

The Rubber Group will exhibit Therban, a hard-wearing hydrogenated nitrile rubber that resists high mechanical and dynamic stresses over a temperature range from -40[degrees] C to 150[degrees] C. "Rubber Row," a joint initiative of Bayer AG, the Dusseldorf Trade Fair Association, and the rubber industry, will house a concentration of 25 rubber processors and Bayer raw materials so that trade visitors can obtain materials, design, and processing information.

The Inorganic Chemicals Group will exhibit varied applications of Silopren, a silicone rubber, and new systems such as silicone rubbers that are expected to find use as self-lubricating rubbers and as flame-retardant formulations. Inorganic colored and white pigments from the Pigments and Ceramics Group also will be presented.

Latest developments for the automotive industry will be brought together in an Automotive Center at the Bayer stand. The possibilities for material, chemical, and energy recycling will be demonstrated and explained with the aid of specific examples.

Bayer also will repeat the University Liaison Center that it maintained at K'86 as a platform for the company to introduce itself to potential future employees.

EXPANDED LINES

Hoechst Celanese's commitment to building its global markets, notably with technical and high-performance polymers, as well as its line of "standard" materials, will be strongly demonstrated at K'89. Celanese's three engineering plastic product lines in the early 1980s--polyacetal, nylon, and polyester--grew to 10 lines by 1986, just prior to its acquisition by Hoechst in 1987. Hoechst Celanese's current position, with 13 engineering plastic lines, ranging from polyamides to polyphenylene sulfide, fluoropolymers, thermoplastic alloys, and liquid crystal polymers, will form the nucleus of the company's wide-spectrum exhibit of materials and applications.

New uses for Hostalen reinforced polypropylene in automotive and electrical/electronic markets; high-impact-modified Hostaform polyacetal copolymers, including electrically conductive and extrusion grades; and the broad range of polyester products, including Riteflex polyester elastomers for applications such as automotive bumpers, also will be featured.

Thermoplastics reinforced with long glass fibers, the Celstran materials, and the Fortron polyphenylene sulfides, also will be represented at K'89. Vectra liquid crystal polymers and Hostatec polyetherketone, offering continuous-use temperature to 260[degrees] C, will contribute to Hoechst Celanese's image as a leading global developer and supplier of high-performance tailor-made engineering polymers. An assortment of products, from homopolymers to block copolymers, random copolymers, and blends, and a complete series of reinforced types, will be reflected in the scope of the K'89 displays.

The company says that blends and alloys; amorphous polymers; new processing techniques, notably for blowmolding, extrusion, and thermoplastic composites; tailor-made catalysts; and highly transparent materials are among its active development areas.

LATEST TECHNOLOGY

K'89 will provide visitors with an opportunity to study some of BASF's latest materials and applications technology. Among the exhibits will be the company's amorphous polymers, Ultrason S polysulfone, with temperature stability to 320[degrees] F; Ultrason E polyether sulfone; Ultrax liquid crystal polyester; and Ultrapek, a partially crystalline polyaryl ether ketone with service temperature stability to 500[degrees] F. BASF says that "intense" research and development is being directed at the high-temperature-resistant thermoplastics for potential applications traditionally reserved for metals, glass, and ceramics.

BASF's exhibit will also reflect the increased interest in foam materials for diverse engineering applications. The company's new Neopolen P, based on polypropylene, has attracted interest for use, in addition to protective packaging, in shock absorbing parts, headrests, car side protectors, sun visors, and energy-absorbent bumper core systems.

Glass-mat-reinforced thermoplastics, to spearhead the development of major structural parts, are typified by the company's Elastopreg materials. Engine compartment shieldings, front ends, and integrated seat designs are in the forefront of the application of structural plastics technology that will be represented in the BASF exhibit. Lightweight advanced composites, based on oriented fiber volumes of 60% and more, are exemplified by leaf springs and drive shafts.

About 20 million plastic fuel tanks are installed globally in more than 35 car models. The company says that up to now, the highest substitution rate is in Western Europe, where 50% of all cars are equipped with plastic fuel tanks. BASF's Lupolen 4261A has played a significant role in the penetration of the application.

Considering the increasingly complicated fuel tank shapes, BASF says that it has systematically modified the molecular structure of the material in order to further improve the elongation flow behavior without changing any existing favorable properties.

Among BASF's other materials for K'89 are Elastolit R 4500 polyurea amide for reaction injection molding. The elastomer offers class A surfaces and suitability for on-line coating. Improved thermal and mechanical properties, shorter cycle times, enhanced internal mold release, high stiffness, and low water absorption are features of the new material. Test specimens demonstrate stability at 392[degrees] F.

An expanded range of polymer blends, offering properties that cannot be produced economically by chemical synthesis, also will be exhibited. Included will be the Luranyl, Ultranyl, Ultrablend, and Terblend grades, and the weather-resistant Terblend S and Ultrablend S versions.

PLASTIC HOUSE

General Electric Plastics will have a large exhibit at K'89, which, in addition to featuring its broad range of engineering thermoplastics and announcing new materials, will focus on its plastics concept house, as part of its continuing Living Environment Project. New kitchen and office concepts, emphasizing the parts consolidation, functionality, and improved productivity possible with engineering plastics, also will be introduced.

A screen presentation on GE Plastics' Alpha I machine, which offers a combination of varied major plastics fabrication processes for high productivity and increased cost-effectiveness, will be a major feature of the exhibit.

In addition to numerous displays centering on material selection, design, and processing, the GE Plastics stand will concentrate on presentations relative to optimization of methods for implementation of plastics recycling and resource recovery.

DEVELOPMENTAL VEHICLE

One of the features of the Du Pont Co.'s exhibit will be the initial display of a new developmental vehicle that incorporates about 300 of the company's materials. Accompanying graphics will explain the vehicle's concept and construction.

The overall exhibit will essentially be segmented according to major markets, such as automotive, electrical/electronic, and construction. Among the materials displayed will be recently introduced Hytrel grades; six new Teflon micropowders; and a developmental elastomeric thermoplastic, a nylon/acrylic graft, which provides an economical balance of environmental resistance and temperature capability from -40[degrees] F to 300[degrees] F. Available for testing, the flexible material is expected to be commercial in January.
