Accurate shape and size, fast delivery. Can be used in mobile phones, computers, machinery equipment, electrical products, equipment, screw gaskets, sealing gaskets, etc.
PTFE polytetrafluoroethylene has the following characteristics.
1. Non-stickiness: It has the smallest surface tension in solid materials without sticking any substance. Almost all substances do not adhere to the polytetrafluoroethylene coating film. Very thin films also show good non-sticking performance.
2. High and low temperature resistance: PTFE has excellent high and low temperature resistance, -200 to 260 degrees. It can withstand high temperature to 300 ℃ in a short time, and can be used continuously between 240 ℃ ~ 260 ℃. It has significant thermal stability. It can work at freezing temperature without embrittlement and does not melt at high temperature.
3. Sliding property: PTFE has low friction coefficient and self-lubricating function. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.
4. Moisture resistance: The surface of Teflon is free from water and oil, and it is not easy to touch the solution during the production operation. If there is a small amount of dirt, it can be removed by simple wiping, saving man-hours and improving work efficiency.
5. Abrasion resistance: Under high load, it has excellent abrasion resistance. Under certain load, it has the dual advantages of wear resistance and non-adhesion.
6. Corrosion resistance: PTFE is hardly attacked by chemicals, and can withstand all strong acids (including aqua regia), strong alkali, except molten alkali metals, fluorinated media, and sodium hydroxide above 300 ° C. The role of strong oxidants and reducing agents. Also resistant to various organic solvents, almost insoluble in all solvents.
7. Polytetrafluoroethylene has poor radiation resistance. It will be degraded after being exposed to high energy radiation, and the electrical and mechanical properties of the polymer will be significantly reduced.
PTFE is widely used in atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instrument, instrument, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgical smelting and other industries. High and low temperature, corrosion-resistant materials, insulation materials, anti-stick coatings, etc. have become irreplaceable products.
