PTFE Overview

PTFE is a soft fluoropolymer mechanical plastic with exceptional resistance to high temperatures, chemicals, corrosion and stress cracking.

PTFE features impressive heat, mechanical toughness, electrical and low friction properties, making it the material of choice for many high heat and low friction applications.

PTFE plastic is available in FDA approved, electrical, mechanical, glass-filled and bearing grades.
