Teflon properties
Polytetrafluoroethylene (abbreviated as Teflon or [PTFE, F4]) is widely used in the world as "Plastic King", Chinese brand name "Teflon", "Teflon", "Teflon" , "Teflon", "Teflon" and so on. It is made by the polymerization of tetrafluoroethylene polymer compounds, the structure of the formula is - [- CF2-CF2-] n-.


High temperature - working temperature up to 250 ℃. Long-term use of temperature 200 ~ 260 degrees.


Low temperature resistance - Good mechanical toughness; 5% elongation even at temperatures down to -196 ° C. It is still soft at -100 degrees.


Corrosion resistance - is inert to most chemicals and solvents, resistant to acids and bases, water and various organic solvents. Able to aqua regia and all organic solvents.


Weather resistant - the best aging life in plastics.


High lubricity - is the lowest friction coefficient in solid materials. Has the smallest coefficient of friction in plastic (0.04). More smooth than ice.


Non-stick - is the smallest surface tension in a solid material and does not adhere to anything.


Non-toxic - with physiological inertia, as long-term artificial blood vessels and organs implanted in the body without adverse reactions.


Anti-aging - Irradiation resistance and low permeability: long-term exposure to the atmosphere, the surface and properties remain unchanged.


Non-flammable - oxygen limit index below 90.


Acid and alkali - insoluble in strong acids, bases and organic solvents (including magic acid, that is, fluorine antimony sulfonic acid).


Anti-oxidation - can withstand strong oxidizer corrosion.


Insulation - Excellent electrical performance, ideal for Class C insulation, a newspaper thick layer can block 1500V high voltage. Its electrical insulation is not affected by temperature. Dielectric constant and dielectric loss over a wide frequency range are low, and the breakdown voltage, volume resistivity and arc resistance are high.


Acid-base - neutral.

Established in 1989, Zhejiang Deqing Conceptfe Plastic Products Co., Ltd,named  Deqing Tonghe Plastics Research Institute before,is now developed into leading and professional manufacturer of polytetrafluoroethylene (PTFE) and other engineering plastics from Zhejiang province and become a member of China Plastic Association and Fluorine Plastics Processing Committee.
