Product Description
Silica Filled PTFE Gasket Sheet – Enhanced Sealing for Strong Acids, Solvents & Hydrocarbons
Kaxite Sealing is a leading China-based manufacturer and supplier of silica filled PTFE gasket sheets (Model KXT 511) – a high‑performance, silica‑reinforced PTFE sheet material engineered for demanding sealing applications. Unlike standard PTFE, the silica filler significantly enhances creep resistance, compressive strength, and sealing performance while maintaining the exceptional chemical inertness of PTFE. This unique combination makes it the ideal gasket material for strong acids (except hydrofluoric acid), solvents, hydrocarbons, steam, and aggressive chemical environments where conventional PTFE may creep or relax under load.
As a trusted factory direct supplier in China, Kaxite offers custom thicknesses and sheet sizes, FDA‑compliant grades, and competitive wholesale pricing. Request your price list and free sample →

Frequently Asked Questions – Silica Filled PTFE Gasket Sheet
What is silica filled PTFE gasket sheet?
Silica filled PTFE gasket sheet is a high‑performance sealing material made from PTFE resin blended with silica filler. The silica reinforcement improves creep resistance, compressive strength, and sealing performance while maintaining PTFE's excellent chemical inertness.
What media is silica filled PTFE suitable for?
It is suitable for strong acids (except hydrofluoric acid), solvents, hydrocarbons, steam, water, cryogenic fluids, hydrogen peroxide, and a wide range of aggressive chemicals used in the chemical, petrochemical, and pharmaceutical industries.
What are the advantages of silica filled PTFE over virgin PTFE?
Silica filled PTFE offers reduced creep relaxation, better anti‑leakage performance, higher compressive strength, and longer service life compared to virgin PTFE – making it more reliable in demanding sealing applications.
What thicknesses and sizes are available?
Standard thicknesses range from 0.5 mm to 6.0 mm, with sheet sizes up to 1500×1500 mm. Custom thicknesses and dimensions are available upon request.
Is silica filled PTFE FDA‑compliant?
FDA‑compliant grades are available upon request for food, beverage, and pharmaceutical contact applications. Please specify your requirements when ordering.
