Technical Data Sheet
Eastar™ Copolyester MN211 Natural


Applications
  • Blood contact and dialysis
  • Drug delivery
  • Fluid administration
  • Medical devices
Key Attributes
  • Chemical resistance to most medical solvents including lipids and IPA

Product Description

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.
