Thermosets & Composites. (What to See at NPE 2003).While there are only a handful of exhibitors at NPE NPE NullPointerException (Java) NPE Network Processing Engine NPE National Policy on Education NPE National Plastics Exposition NPE Natural Penis Enlargement NPE Nutrition Program for the Elderly involved in thermosets thermosets, materials that can not be softened on heating. In thermosetting polymers, the polymer chains are joined (or cross-linked) by intermolecular bonding. Thermosets are usually supplied as partially polymerized or as monomer-polymer mixtures. and composites, it looks like there may be significant news in one area of leading-edge technology: fuel cells. There were advance hints that GE Plastics and BMC (BMC Software, Inc., Houston, TX, www.bmc.com) A leading supplier of software that supports and improves the availability, performance, and recovery of applications in complex computing environments. Inc. would announce at the show a new conductive BMC material for fuel-cell plates based on GE's brand-new PPO-based thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. called Noryl ETX ETX - End Of Text . BMCI BMCI Banque Marocaine du Commerce et de l'Industrie (Morocco) BMCI Bio-Math Connect Institute (Rutgers University, Piscataway, NJ) BMCI Bulk Moulding Compounds Inc. (West Chicago, IL) will also introduce a new conductive adhesive and water-fight seal for assembling bipolar plates into fuel-cell stacks. It is said to provide better conductivity across the bond line than simply pressing the plates together without a bond. Meanwhile, Hull/Finmac will be discussing special compression presses for molding bipolar plates. Laboratory presses Hull won't be the only compression-press builder at NPE--Fontijne Grotnes of the Netherlands and Labtech Engineering of Thailand will also be featuring their lab-scale equipment. Also EAS (Electronic Article Surveillance) A security system for preventing theft in retail stores that uses disposable label tags or reusable hard tags attached to the merchandise. Mold & Die Change Systems will introduce a magnetic QMC QMC abbr. quartermaster corps system that can withstand the heat of thermoset molds and platens. In other equipment, Maxi-Blast is bringing its latest deflashing system and Flow Robotic Systems will discuss automated cells for finishing SMC parts. The fast-growing field of pultrusion Pultrusion is a continuous process of manufacturing of composite materials with constant cross-section whereby reinforcing fibers are pulled through a resin, possibly followed by a separate preforming system, and into a heated die, where the resin undergoes polymerization. will also have a presence at the show. Crown Pultrusion will discuss die manufacturing, and Scheer Bay Co. will unveil a cutter for thermoplastic pultrusions used to make long-fiber composites. Besides BMCI, three other suppliers of thermoset materials will be at the show--Industrial Dielectrics and two producers of silicone rubbers, Dow Corning and Wacker Wacker may refer to:
Exhibitor Listings Includes compression presses, deflashers, and materials. New developments appear in boldface type. BULK MOLDING COMPOUNDS, INC. Booth 7535 Introducing a conductive BMC and eSealant 9400, a one-step bonding adhesive and water-tight seal for assembling bipolar plates into fuel-cell stacks. It eliminates the need for gasketing and increases conductivity across the bond line compared with unbonded plates. Also presenting new patented technology for gas-assist injection molding with thermosets. (Formal presentation on the subject at booth on June 25 at 2:30.) CROWN PULTRUSION CO.
