Polyplastics USA, Inc. TOPAS® COC 6017S-04 (ISO)

TOPAS® is the trade name of a cyclic olefin copolymer (COC) developed by TOPAS ADVANCED POLYMERS GmbH, it is an amorphous transparent copolymer possessing a cyclic olefin structure. TOPAS® has been evaluated highly in the market as a resin with optical properties comparable with PMMA (polymethyl methacrylate, acrylic resin), superior heat resistance to PC (polycarbonate), and superior dimensional stability to PMMA and PC. Furthermore, is a material that is suitable for modifier applications for existing materials, where it can improve the water vapor barrier, increase rigidity, enhance heat resistance, and make materials easier to cut. Here, application activities are underway in the packaging materials sector. Characteristics · Excellent optical properties TOPAS® possesses optical properties comparable with PMMA and superior heat resistance to PC. Moreover, it possesses excellent dimensional stability due to the fact that it absorbs almost no moisture. These attributes have earned the resin a high evaluation in the optical market sector.
