PTFE Gaskets - Teflon Gaskets

_______________________________________

What is PTFE Gasket ?

- 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.

Different Type PTFE Gaskets

- Virgin PTFE Sheet, Graphite Filled PTFE Sheet, Barium Sulfate Filled PTFE Sheet, Carbon Filled PTFE Sheet, PEEK Filled PTFE Sheet, Silica Filled PTFE Sheet, Bronze Filled PTFE Sheet, Glass Filled PTFE Sheet

_______________________________________

• Virgin PTFE Gasket

- 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.

• Expanded PTFE Gasket

- 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.

• Glass Filled PTFE Gasket

Glass fibre gasket is used as a PTFE filler as it offers much-improved compression and wears properties. The material may also be inert gas sintered to further improve creep properties and reduce porosity and gas permeability, whilst also contributing to a loss of tensile properties.

• Graphite Filled PTFE Gasket

- The product is sintered with PTFE and graphite at high temperature. Advantages: low friction coefficient, good compressibility, better wear-resistant; suitable for chemical, petrochemical, hydrocarbon reaction and power plants.

• Barium Sulfate Filled PTFE Gasket

Barium Sulfate Filled PTFE Gasket is the most chemically resistant of PTFE material variants, and is made with 100% Virgin PTFE with Barium Sulfate as the filler. Style 7536 is manufactured by a unique process that structures the composition into fibers.

• Carbon Filled PTFE Gasket

Carbon-filled PTFE is available in different compositions depending on the material to filler ratio. Of this, PTFE 75% and 25% carbon is the most common ratio.

• PEEK Filled PTFE Gasket

- PTFE filled PEEK is a material that exhibits extremely good sliding and wear properties.

• Silica Filled PTFE Gasket

- PTFE gasket sheet with silica filler is a high performance, silica filled PTFE sheet material designed for use with strong acids, solvents, hydrocarbons, and other aggressive media.

• Bronze Filled PTFE Gasket

- Bronze Filled PTFE Gasket: The addition of Bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity.

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.
