The mechanical properties of PTFE in a wide temperature range of -196 to 260, which is characterized by high temperature and low temperature, are maintained.
Chemical corrosion resistance and weathering resistance of the alkali metal, except for the melting
of the alkali, PTFE is almost free from any chemical reagent. Such as in concentrated sulfuric acid, citric acid, hydroelectric acid, even in aqua regia in boiling, the weight and performance did not change, almost insoluble in all solvents, only in more than 300 DEG C is slightly soluble in total alkane (about 0.1 g / 100g). PTFE does not absorb moisture, does not burn, the oxygen, ultraviolet radiation are very stable, so has excellent weather resistance.
The dielectric constant and dielectric loss of the electric properties of PTFE in a wide frequency range are very low, and the breakdown voltage, the volume resistivity and the arc resistance are both high.
Insulation: the impact of the environment and frequency, the volume resistance of 1018 ohm cm,
medium loss is small, high breakdown voltage.
High and low temperature resistance: the effect of temperature is small, wide temperature range,can use the temperature of -190~260 DEG C.
Self - lubricating: with the smallest friction coefficient in plastics, it is an ideal oil - free lubricating material.
The surface is not sticky: the known solid materials can not adhere to the surface, is a surface can be the smallest of solid materials. Resistance to atmospheric aging, radiation resistance and low permeability: long-term exposure to the atmosphere, surface and performance remains the same.
Non - Burning: the limiting oxygen index is below 90. Mechanical properties of ptfe. Has very low surface energy.
