Remark	1.Above data is only for reference.It may vary according to different processing method and sample. 2.These data can’t be simply transferred to the finished parts.The applicability of materials for specific applications should be tested by the processor and user. 3.These technical parameters are used as a help.They do not represent a promise of performance. 4.Above specification “+” represents resistant, “-” represents resistless, “0″ represents it depends.

Properties
1. High temperature resistance, use working temperature up to 250 degrees Celsius
2. Low temperature resistance, good mechanical toughness
3. Good corrosion resistance, inert to most chemicals and solvents, resistant to strong acid, strong alkalis, water and various organic solvents
4. Weather resistance
5. High lubrication, with the smallest coefficient of friction in plastic
6. Non-toxic, physiologically inert, long-term implantation as artificial blood vessels and organs without adverse reactions
7. Good electrical insulation
8. Non-adhesive, the smallest surface tension in solid materials and does not adhere to any substance
9. Cold flow property
10. The coefficient of linear expansion of PTFE is 10 to 20 times than that of steel, which is larger than that of most plastics, and its linear expansion coefficient changes very irregularly with temperature
Application
Widely used as high temperature resistance materials, corrosion resistance materials, insulating materials, anti-stick coatings in industries such as atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instrumentation, construction, textile, metal surface treatment, pharmaceutical, medical, metallurgical smelting, etc.
