Audited Supplier PTFE is one of a class of plastics known as fluoropolymers.
PTFE Sheet is made of a high molecular weight fluoropolymer named Polytetrafluoroethylene, commonly referred to as PTFE. PTFE is a fluorocarbon, meaning it consists wholly of carbon and fluorine bonds and it is non-reactive in part because of the strength of the carbon-fluorine bonds. PTFE Sheet material is hydrophobic, and it possesses excellent thermal and electrical insulating properties. It has a high tensile strength. PTFE has one of the lowest coefficients of friction out of any solid.
This material is highly versatile and is often referred to when by brands that use Teflon, a PTFE based formula material that is oftentimes synonymous with non-stick coated cookware. It is preferred by the building and construction industry for its strong non-reactive nature and used to make containers and piping where reactive chemicals may come into contact with pipes. Valves and fittings are commonly made of PTFE sheet. It is also UV resistant.
Performance
Extremely resistant to chemical corrosion, it is non-aging, non-sticking and remain stable at -180°C ~ 260°C temperature without load.
It has the lowest friction coefficients in known solid materials.
Higher durability, corrosive resistance higher heat resistance.
Excellent anti-aging, electric insulation properties, good performance for sealing.
