Description

PTFE gasket is also called Teflon gasket、a flat gasket made of ptfe rod、tube and plate by mechanical molding or cutting.

Advantage

• High temperature resistance -- operating temperature up to 250℃.
• Low temperature resistance -- good mechanical toughness; Even when the temperature drops to -196℃, 5% elongation can be maintained.
• Corrosion resistance - inert to most chemicals and solvents, resistant to strong acids and bases, water and various organic solvents.
• Weather resistance - has the best aging life of plastics.
• High lubrication - the lowest friction coefficient of solid materials.
• Non-adhesion - is the minimum surface tension in solid materials, does not adhere to any material, mechanical properties of its friction coefficient is very small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface. And because of the very low intermolecular force of fluorine - carbon chain, ptfe is non-viscous.
• With physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reactions.

Application

• Suitable for bio-pharmaceutical, food, chemical, oil refining, military, ship, aerospace, machinery and other high sealing, high corrosion environment.
• Suitable for heat exchanger, FRP, compression frame flange, steam vessel flange, liquid and gas system water system, fan frame and other construction sites.
• Used for industrial mechanical seals.
