Tribological characteristics of engineering thermoplastics, including Stanyl, Plaslube and Nylatron, are featured in the company's 28-page, four-color brochure. This literature assists the plastics parts designer in understanding the fundamentals of polymer wear and friction. Methods of characterizing these tribological properties, as well as the effective interpretation of the results in relating their use to dynamic applications, are explored. In addition to information about individual material capabilities, the brochure examines the complex inter-relationship of application conditions to the successful operation of dynamic thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. parts. A compact disc is included containing more detailed information. (DSM 1.

An updated selection guide on styrenic block copolymers is available from the company. The family of styrenic block copolymers is composed of styrene-butadiene-styrene (SBS See Small Business Server. ) and styrene-isoprene-styrene (SIS) types of both linear and radial, and diblock configurations. These block polymer structures are characterized by a combination of high tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its and rubber-like elasticity with the ease of thermoplastic or solution processing. Vulcanization vulcanization (vŭl'kənəzā`shən), treatment of rubber to give it certain qualities, e.g., strength, elasticity, and resistance to solvents, and to render it impervious to moderate heat and cold. or chemical crosslinking are not required to produce tough, rubbery articles.

The Mix Vision system is featured in a six-page, four-color brochure that highlights the system functions and architecture. The systems are scaleable from basic mixing cycle control to complete mixing In evolutionary game theory, complete mixing refers to an assumption about the type of interactions that occur between individual organisms. Interactions between individuals in a population attains complete mixing if and only if the probably individual x process integration, including weighing, mixing, mills, batch-offs, scheduling, inventory, management information, laboratory and business system links. Running under Windows NT, Mix Vision utilizes Microsoft SQL Server A relational DBMS from Microsoft that is a major component of the Windows Server System. It is Microsoft's high-end client/server database and is closely integrated with Microsoft Visual Studio and the Microsoft Office System. , providing an open architecture. The system is said to greatly enhance ISO (1) See ISO speed.

A four-page brochure summarizes the high-performance capabilities of Alcryn MPR (MultiProtocol Router) Software from Novell that provides router capabilities for its NetWare servers. It supports IPX, IP, AppleTalk and OSI protocols as well as all the major LANs and WANs. for automotive applications. The literature highlights how manufacturers can stay competitive by using Alcryn MPR to produce high-quality automotive parts while controlling costs. It also provides comparative data demonstrating that A1cryn MPR is said to be the alternative to soft thermoplastic elastomers and vulcanized rubber, as it provides superior durability and processes easily on standard plastics machinery, according to the literature. Current applications include weather seals, gaskets, cable covers, outer-belt strips, reveal moldings, fuse holders, seat-belt guides, hinge bumpers, and windshield and backlight back·light n.
