Eastar™ MN211, Natural

About
Meets ISO 10993 and/or USP Class VI biocompatibility requirement. Eastar™ Copolyester MN211, Natural contains a mold release for improved ejection. It is a brilliantly clear polymer with good impact strength, chemical resistance, dimensional stability, and low shrinkage rates. The slower rate of crystallization of this material makes it excellent for use in hot runner systems with valve or thermal gates. 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.
