Expanded PTFE Gasket

Expanded PTFE Gasket

Kaxite expanded PTFE gasket is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacturing. This process ensures that the molecular chains from which the PTFE is constructed,do not arrange themselves into set patterns.This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required,expanded PTFE also possesses the unique chemical resistance of virgin PTFE .

Product Description

Expanded PTFE Gasket is cut from Expanded PTFE gasket sheet, our expanded PTFE gasket sheet made with only pure PTFE resins.

It is suitable for use in steel flanges as well as flanges where a highly compressible gasket is required. Expanded PTFE Gasket is also

suitable for sealing flanges with irregular surfaces. It will not exhibit the cold flow problems associated with virgin PTFE or the hardness

problems of some other filled PTFE products. It has excellent sealability, cuts easily, and separates cleanly from flanges after use

 

Advantages:

• A wide range of applications for all type of flanges

• Gasket easy cut maked

Higher temperature

• Multi-directionally expanded PTFE has exceptional mechanical strength

• Higher temp than other PTFE sheet

Cost savings

• High quality - long life - reduce changing gasket period - cut cost

• Easy and simple to install gaskets, a used gasket changed easily

Large sizes

 Sizes from 1/2'' - 24'' available, welcom Custom gaskets

 Offers some of the largest sheet sizes in the industry
