Description

PTFE GASKET – IDEAL GASKET SOLUTION FOR HIGHER BOLT LOADS EQUIPMENT.
PTFE Gasket is made of synthetic fluoropolymer of tetrafluoroethylene.

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.

MATERIALS TYPES

Virgin Teflon gaskets. Virgin Teflon gaskets are 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.
Filled Teflon gaskets. Filled Teflon gaskets are made from virgin PTFE material with an added substance to improve their sealing properties. The gaskets materials exhibit strong physical characteristics, the strength can be altered depending on the type of filler that is used to enhance the material.
Expanded Teflon gaskets. Expanded Teflon gaskets are produced through virgin PTFE being expanded in a manner that creats uniform tension strength across the material. This process results in a PTFE material that carries no structural weakness and more flexible. They also exhibit the unique chemical resistant properties of virgin PTFE due to the fact that no additives are added.
