Chemical Resistance Modified PTFE , Waterproof PTFE Seal Gasket

This part is made of 100% PTFE and CNC machined.

 

The performance of PTFE:


PTFE has a strong portfolio of carbon-fluorine and ultra high molecular, which years the following excellent features:
1. Wide working temperature range: -200°C~+250°C
2. Chemical resistance against most of all chemicals
3. Non-stick
4. Ultra low abrasion
5. Non-flammable
6. Good electric character
7. Great mechanical property
8. No aging

 

Waterproof and Ultraviolet-ray-proof
Non-toxic
