ETFE Unfilled

ETFE Unfilled


What is the Material: ETFE Unfilled is a semi-crystalline material.

Key Material Features: This material is beneficial in applications requiring impact strength, chemical resistance, and electrical properties.

Other Considerations: This material is a fluoropolymer, like PTFE (Teflon), but it has greater strength and stiffness.
