CompositesWorld.com 59 » RESIN SYSTEMS TECHNOLOGY Two new cycloaliphatic epoxies Daicel USA (Ft. Lee, NJ, US) has launched two new grades of cycloaliphatic epoxies, Celloxide 8000 and Celloxide 8200, ofering good heat resistance and strong fexural modulus properties. These improvements, says Daicel, have been achieved without sacrifcing the superior transparency of the Celloxide brand. Molded properties of Celloxide 8000 neat resin include a T g of 354°C (TMA) and a fex modulus of 3,705 MPa, as compared to a T g of 155°C and a modulus of 2,532 MPa for a bisphenol-A epoxy. The Celloxide 8200 is said to exhibit an even higher modulus of 4407 MPa. Daicel says the Celloxide epoxy systems are known for their propensity to be molded with less energy in a short time, resulting in a cured product with good mechanical strength. Furthermore, the cycloaliphatic epoxies manufactured by Daicel are reportedly naturally very low in viscosity and solvent-free, thereby allowing for green processing. www.dalcel.com » FIBER-REINFORCED THERMOPLASTICS Long glass-fiber polymers Trinseo (formerly Styron, Horgen, Switzerland) has launched the ENLITE line of structural polymers, targeted at semi-structural applica- tions. The line is designed to be customizable to the application. Its frst two products in the line are branded ENLITE long glass-fber polypropylene (LGF-PP), and ENLITE glass-fber (GF) alloys. ENLITE LGF-PP provides glass-fber loadings to a maximum of 60% in a polypro- pylene matrix. But Trinseo says that customers, working with the Trinseo technical team, have the fexibility to achieve the direct proportion of glass-fber content they need for a particular application by diluting the product with neat PP. ENLITE GF is designed, says Trinseo, to "provide a bridge between the glass-flled polypropylene solutions of today and the enhanced carbon-fber solutions of the future." For example, when the design of the part necessitates thick walls to meet stifness requirements, or must replace a steel or aluminum original, GF alloys are said to provide a possible solution. The frst product designed in the GF alloys range is the GF-ABS alloy, which is a glass fber-reinforced concen- trate, the fber volume fraction of which can be adjusted by dilution with ABS. www.tinseo.com SGS has designed specifc cutting tool technologies that combine substrate, geometry, edge preparation and coating to withstand the complex conditions of Composite applications requiring minimal fber breakout and delamination.

The material was initially developed specifcally as a wall coating for operating theaters in hospitals. LAMILUX notes that medical experts estimate that 15,000 patients die from hospital infection every year. Other applications could include refrigerated warehouses and vehicles as well as in processing areas and slaughter houses. The material is under trial at the Asklepios Clinic in Bad Abbach, Germany. LAMILUX developed the technology with nanosilver specialist Rent-a-Scientist (Regensburg, Germany). www.lamilux.de NEW PRODUCTS
