Lanxess AG (Leverkusen, Germany and Pittsburgh, Pa.), a recent spinoff from Bayer Corp., made a splash at the show with its innovative glass fiber technology. The company, which produces only glass fiber and basic thermoplastics for compounded pellets, employs a much less costly "direct chopped technology": fibers are chopped immediately after sizing, skipping all winding steps. The chopped fibers fall into a self-contained silo that becomes a bulk truck trailer when turned on its side, for transport from the glass plant in Belgium to the company's compounding facility in Germany, where a patented pneumatic conveyor combining vacuum and direct air pressure quickly unloads the silo directly into the pelletizing process stream. The low-cost manufacturing method makes it possible to affordably customize fiber dimension and sizing to meet each customer's application needs, says the company. lanxess.gocomp.biz/1

Lectra (Marietta, Ga.) exhibited its ProSpinTechTexST, a plotter-based, single-ply cutting machine, designed for prototyping and low-quantity production. Also presented on the stand was DesignConcept TechTex, a software program that ensures extremely accurate 3-D and 2-D model flattening, regardless of model complexity. This provides designers with a realistic simulation of the final rendering and enables them to analyze technical and economic feasibility before the critical prototype development phase. Cost estimates can be calculated early in development, easing the decision-making process. lectra.gocomp.biz/7

Leybold Vacuum France SA (Les Ulis, Cedex, France) promoted its SOGEVAC Central Vacuum Systems for RTM applications. Since RTM processes sometimes require two vacuum pressure levels, one for closing the mold and an adjustable pressure level for resin injection, this system combines two independent pressure adjustment and delivery units that are powered by a single vacuum pump. The system is available in four configurations: two portable units with casters, each with two 60-liter pressure vessels, and two fixed-position units, each with two 150-liter vessels. leybold.gocomp.biz/1

Noveon Division, Lubrizol Ltd. (Blackley, Manchester, U.K.) added to its additives line the new SOLPLUS D150 dispersing agent, designed for wetting/ dispersion of fillers (e.g., ATH, calcium carbonate), pigments (e.g., carbon black, titanium dioxide and/or silica in epoxy resins), while reducing the resin's viscosity.
