Filled PTFE

Basic Properties & Grades
Filled PTFE

PTFE is available in many different Grades as Virgin PTFE, Chemically Modified PTFE, Carbon Filled PTFE, Glass Filed PTFE, Carbon / Coke Filled PTFE, Graphite Filled PTFE, Bronze Filled PTFE, Bronze + Molybdenum Disulphide Filled PTFE, Aluminum Oxide Filled PTFE, Calcium Fluoride Filled PTFE, Stainless Steel Filled PTFE, Mica Filled PTFE, Glass + MoS2 Filled PTFE, MoS2 Filled PTFE, Chemically Modified PTFE etc.

The Filled grades of PTFE can be compounded & customized for specific service conditions & applications. Filled PTFE grades have specific properties improvement based on filler, type of filler & percentage of filler.
