Characteristic
(1) Chemical stability: Almost all chemical resistances, strong acids, strong bases, and organic solvents do not affect it.
(2) Thermal stability: The cracking temperature is above 400 . Therefore, it can operate normally within the temperature range of -200 to 300 , and can reach up to 250 ° C Suitable for various high-temperature, strong acid, strong alkali chemical fields.
(3) Friction reducing properties: PTFE material has an extremely low friction coefficient of only 0.02, which is 1/40 of rubber
(4) Self lubrication: The surface of PTFE material has outstanding self-lubricating properties, and almost all viscous substances cannot adhere to its surface.
Appliaction
High temperature resistance - operating temperature up to 250 .
Low temperature resistance - with good mechanical toughness; Even if the temperature drops to -196 , it can maintain a 5% elongation rate.
Corrosion resistance - exhibits inertness towards most chemicals and solvents, and can withstand strong acids, alkalis, water, and various organic solvents.
Climate resistance - has an aging life in plastics.
High lubrication - is the highest friction coefficient in solid materials.
Non adhesive - refers to the small surface tension in solid materials that does not adhere to any substance.
Non toxic - physiologically inert, with no adverse reactions when implanted into artificial blood vessels and organs for a long time.
The weaving process adopts arrow loom plain weave, diagonal weave, and dense weave, and the weaving mesh can be controlled between 15 mesh and 400 mesh.
Polytetrafluoroethylene gas-liquid filter can be used for a long time in any type of acidic or alkaline medium. Polytetrafluoroethylene gas-liquid filter can withstand the corrosion of hydrofluoric acid, phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, various organic acids, organic solvents, and other highly corrosive chemical media. Even highly corrosive aqua regia (a mixture of concentrated sulfuric acid and concentrated nitric acid) is helpless against it. It is widely used in industries such as aviation, chemical, electronics, bridges, textiles, machinery, papermaking, ceramics, etc.
