PTFE

Overview

Kormax PTFE [technical name Poly Tetra Fluoro Ethylene] is a fluoro-carbon-based material with excellent temperature and chemical resistance. Kormax PTFE is often used for non-stick applications due to its extreme low coefficient of friction. Whilst Kormax PTFE is a very dense material, compared to other plastic materials, it is quite soft and has low abrasion resistance. It is also produced with different additives such as glass, carbon, bronze and stainless steel to improve various physical properties of Kormax PTFE.

Common Applications

High temperature bearings
Insulators
Low friction building pads
Seals and gaskets
Chemical processing equipment

Key Features
