Eastar™ MN021 Natural

About
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. This product has been GREENGUARD INDOOR AIR QUALITY CERTIFIED The GREENGUARD INDOOR AIR QUALITY CERTIFIED Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute (GEI). GEI is an industry-independent, non-profit organization that oversees the GREENGUARD Certification Program. The GREENGUARD Certification Program is an industry independent, third-party testing program for low-emitting products and materials for indoor environments.
