ECTFE Unfilled
ECTFE Unfilled Overview
What is the Material: ECTFE Unfilled is a semi-crystalline material.
Key Material Features: This material is beneficial in applications requiring strength, impact resistance, temperature resistance, chemical resistance, electrical properties, and surface smoothness.
Other Considerations: This material is a fluoropolymer, like PTFE (Teflon), but it has greater surface smoothness.
