TRITAN™ MX731

Eastman Tritan™ Copolyester MX731 is an amorphous product with excellent appearance and clarity. Eastman Tritan™ Copolyester MX731 is a high flow medical grade of Eastman Tritan™ that has viscosity reductions of 40-50% relative to Eastman Tritan™ Copolyester MX711. Eastman Tritan™ Copolyester MX731 contains a mold release derived from vegetable based sources. Eastman Tritan™ Copolyester MX731 has many outstanding features that include excellent toughness, hydrolytic stability, heat resistance, chemical resistance, and melt flowability. Eastman Tritan™ Copolyester MX731 has been formulated for medical devices. Eastman Tritan™ Copolyester MX731 has been tested for FDA/ISO 10993 and USP Class VI Biological Evaluation testing after Gamma and ETO sterilization.
