RAUH Polymers Optimum® 800 COPE
Categories: Polymer; Thermoplastic; Elastomer, TPE

Material Notes: Optimum® copolyesters are a new development in polymer technology. They can meet the requirements and desires of engineers for the most demanding applications and cost effectiveness to enable the broadest possible applications. Optimum is a hard block copolyester of either, or both, crystalline and amorphous blocks, depending on grade. The Optimum use is for applications that require high scratch and mar resistance, heat, UV and chemical resistance. The appearance of Optimum can be optically clear. Optimum in colors and tints can accept fillers such as metal flake without the loss of properties. The processability is superior, and the cost saving is tremendous with the elimination of painting parts. As with other engineering thermoplastics, Optimum resin can be injection molded using standard equipment. The characteristic rheological behavior makes it easy to process, with good fill over long flow lengths at low pressure, with faster cycle times. Optimum grades cal also be extruded, blow molded or thermoformed.

Basic Properties: Optimum® copolyesters are a class of engineering polymers offering unmatched properties in combinations of high level mechanical, thermal, chemical and electrical properties:
