china Teflon PFA Insulation: Not affected by the environment and frequency, the volume resistance can reach 1018 ohm·cm, the dielectric loss is small, and the breakdown voltage is high.
High and low temperature resistance: little change in temperature, wide temperature range, usable temperature -190~260℃.
china Teflon PFA self-lubricating property: It has the smallest friction coefficient among plastics and is an ideal oil-free lubricating material.
Surface non-stick: None of the known solid materials can adhere to the surface, and it is a solid material with the smallest surface energy.
china Teflon PFA Resistance to atmospheric aging, radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and properties remain unchanged.
Incombustibility: The oxygen limit index is below 90.
china Teflon PFA mechanical properties
Its friction coefficient is extremely small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface. And because the fluorine-carbon chain intermolecular force is extremely low, PTFE is not sticky. china Teflon PFA maintains excellent mechanical properties in a wide temperature range from -196 to 260 °C. One of the characteristics of perfluorocarbon polymers is that it does not become brittle at low temperatures. Chemical and Weather Resistance PTFE is virtually uncorrupted by chemicals other than molten alkali metals.
