PTFE & PCTFE Components for Aerospace and Defense
Manufactured by Centroid Polymer Technologies in Kerala, India
Aerospace sealing and insulation run across extreme temperatures, aggressive fluids and tight weight budgets, and the parts have to be dimensionally stable.
Centroid machines and moulds PTFE and filled PTFE seals, gaskets and dielectric insulators. We supply PCTFE parts for cryogenic liquid oxygen, nitrogen and helium service, PTFE-bonded diaphragms and bearings, and etched PTFE for bonding to metals and elastomers.
Filled PTFE grades with glass, carbon, bronze and graphite improve wear resistance and creep strength for dynamic seals and bearings.
What Aerospace & Defense buyers need
- Operation from cryogenic to high temperatures
- Low outgassing and chemical inertness
- High dielectric strength for avionics insulation
- Dimensional stability and low creep under load
- Bondability through PTFE etching
Standards commonly specified
- AMS / AS specs
- MIL-I-46852C
- SAE AS 1604
Compliance varies by product and compound. Ask us for the certificates and test reports for your part.

Frequently asked questions
When should PCTFE be used instead of PTFE?
PCTFE has lower permeability, higher stiffness and less cold flow, which makes it better for cryogenic valve seats and seals in liquid oxygen, nitrogen and helium systems.
What are filled PTFE grades for?
Fillers such as glass, carbon, bronze and graphite raise PTFE's wear resistance and reduce creep, for bushings, bearings and dynamic seals.
Why etch PTFE?
Etching treats the PTFE surface so it can be bonded to metal, rubber or other substrates with adhesives.
