What is PTFE Gasket?
- PTFE (Teflon) gasket is made of synthetic fluoropolymer of tetrafluoroethylene (it is produced directly from pure material). They are used in the majority of general applications due to the most cost-effective type of PTFE material and possessing the greatest physical and electrical insulation properties.
- It has highly resistant to chemicals, solvents, caustics and acids, except for alkali metals and fluorine gas. In addition, PTFE also has a very low surface energy and conforms to FDA regulations.
- PTFE gasket provides excellent sealing performance in corrosive environments.
- It can be used as flange gasket in the chemical industry, machine and equipment industry and piping.
- Our Virgin PTFE Gasket, PTFE cut gasket, PTFE solid ring gasket are available in 1.5 mm, 2 mm & 3 mm, 4 mm, 5 mm, 6mm thickness

Why Should You Choose PTFE Gasket
- PTFE Gasket offers super low friction, high chemical resistance, low and high temperature capability, resistance to weathering, electrical and thermal insulation, and unrivalled "slipperiness"
Is PTFE Gasket Chemical Resistant
- PTFE gasket is pretty much safe against most known elements and compounds. It is attacked only by the alkaline metals in the elementary state, by chlorine trifluoride, and by elementary fluorine at high temperatures and pressures. PTFE doesn’t dissolve in most solvents at temperatures up and around 300°C. Fluorinated hydrocarbons can cause an amount of expansion which is not permanent. Some oils which are highly fluorinated and at temperatures over 300°C can inflict a dissolving affect upon this excellent engineering plastic.
Key Features of PTFE Gasket
- Excellent sealing at high temperatures and pressures.
- Non-corrosive, non-wetting, non-contaminating and odourless.
- Excellent electrical and thermal insulation in virgin PTFE form.
- Excellent chemical and mechanical resistance.
- Very low gas leakage (complies with German Fugitive Emission Regulation TA-Luft).
- Minimized cold-flow and creep behaviour.
- Ideal for aggressive chemicals.
- Long service life.
- Easy to handle and cut.
Application of PTFE Gasket
- PTFE gasket has excellent non-sticky property, it is easier to remove any foreign. articles.It is widely used in guide rail, storage tank, valve, container,corrosion-resistance liner, seal and dielectric materials etc.
- Electrical Applications. (corrosion-resistance, exposure to high and low temperatures)
- Food & Beverage. (secure seals and long product life)
- Petrochemical & Chemical Processing. (corrosion-resistance, exposure to high and low temperatures and high surface wear)
- Pulp and Paper. (long product life)
- Pharmaceuticals. (secure seals and long product life)
- Rail-Tank Car. (high temperature and surface-wear resistant)
