Product Texts

Eastar™ Copolyester MN021 Natural has been tested for FDA/ISO 10993 and USP Class VI Biological Evaluation testing after Gamma and EtO sterilization. Eastar™ copolyester MN021 Natural is a thermoplastic condensation copolymer produced by a continuous melt-phase polymerization process followed by a solid-state polymerization process. It has a relatively high flex modulus and yield strength. This product does not contain a mold release. It is a thermoplastic condensation copolymer produced by a continuous melt-phase polymerization process followed

by a solid-state polymerization process. It has been crystallized.
