White Color Perforated Virgin PTFE Washer Gasket Size Can Negotiable for Sealing fitting
Description
PTFE gasket, also named gasket, is made by cutting PTFE stick, pipe and sheet into flat shape. V shape gasket or valve annulus. It is anti-corrosive, anti-aging and not electric. PTFE PH value is among 0-14. it can have good mechanical strength at -100℃-100℃. The pressure is 10Mpa. Note: when the temperature is lower than -185℃. PTFE gasket will get brickle. Pure PTFE gasket is a kind of clean product. It won’t pollute any substance it touches. It is widely used in the industry of foodstuff and medicine.
Flat gasket is a conducting medium with good high quality. Our plastic insulators are made of different sizes of plastics materials, such as PTFE, PEEK, POM, ULTEM and so on. According to these materials’ special features, such as excellent corrosion resistance, aging resistance, high temperature resistance performance, waterproof, moisture permeability, which can be fully used for all kinds of machinery. The insulators we made will be high quality, good appearance and good property, which have been applied to the market of USA, Europe and so on.
