polytetrafluoroethylene (Teflon or PTFE), commonly known as the “king of plastic”, by the polymerization of tetrafluoroethylene polymer compound has excellent chemical stability, corrosion resistance, sealing, high viscosity lubrication, electrical insulation and good anti-aging endurance. For engineering plastics can be made of PTFE tube, rod, plate, belt, film.
It has been widely used in aviation, aerospace, atomic energy, electronics, electrical appliances, chemical industry, machinery, construction, textile, pharmaceutical and other industrial sectors, and increasingly deep into people’s daily life. Especially the industrial application of PTFE material in corrosion protection, greatly promoted the development of chemical industry.

The basic characteristics of ptfe:
High temperature – working temperature up to 250 DEG C.
Low temperature resistance with good mechanical toughness; even if the temperature drops to -196 DEG C, can keep 5% elongation.
The corrosion of most chemicals and solvents, showing the inertia ability of acid alkali, water and organic solvent.
Weather resistance: the bestaging life.
High oil – is a solidmaterialinthe lowestfriction coefficient.
No adhesion is minimal surface tension in solid materials, no adhesion to any material.

No poison, physical inertia, as artificial blood vessels and organs long-term in vivo without adverse reaction.
