Frequently Asked Questions

What is the difference between PTFE and EPTFE?

PTFE (Polytetrafluoroethylene) is a solid fluoropolymer known for its non-stick and chemical-resistant properties. EPTFE (Expanded PTFE) is a microporous form created by stretching PTFE, offering greater flexibility, conformability, and sealing performance on irregular surfaces.

Are your PTFE products FDA compliant?

Yes, our PTFE materials meet FDA standards, making them safe for use in food processing, pharmaceutical, and medical applications where material safety is critical.

Can you customize PTFE gaskets to our specifications?

Absolutely. We offer custom PTFE gasket manufacturing based on your drawings, dimensions, and application requirements. Contact us with your specifications for a quote.

What industries use your PTFE products?

Our products are widely used in petroleum, chemical processing, electric power generation, steel manufacturing, shipbuilding, water treatment, and paper industries—anywhere reliable, chemical-resistant sealing is required.
