Product Description
Eastman Spectar™ Clear is a copolyester, developed by Eastman to achieve measurably improved sheet clarity and edge color while maintaining the performance characteristics for which Eastman Spectar™ copolyester has become known in the industry. It offers the thermoformability and ease of fabrication of Eastman Spectar™ copolyester along with significantly improved clarity. Eastman Spectar™ Clear also offers approximately double the notch impact strength, 50% higher instrumented impact strength and better chemical resistance when compared to traditional Spectar™ Copolyester.
