PTFE film
★Use above 200℃
PTFE film
Polytetrafluoroethylene (abbreviated PTFE)
Due to the special process temperature of 200~300ºC, few materials can withstand this temperature condition.
PTFE has very excellent chemical properties.
Corrosion resistance: Able to withstand the effects of all strong acids, strong bases, strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and molten strong alkali.
Insulation: not affected by environment and frequency, resistivity up to 1018 ohm·cm, small dielectric loss, high breakdown voltage.
High and low temperature resistance: Little effect on temperature, wide temperature range, usable temperature -190~300 ℃.
Self-lubricating: It has the smallest friction coefficient among plastics and is an ideal oil-free lubricating material.
Surface non-stickiness: No known solid material can adhere to the surface. It is a solid material with the smallest surface energy.
Atmospheric aging resistance, radiation resistance and low permeability: after long-term exposure to the atmosphere, the surface and performance remain unchanged.
Non-flammability: Oxygen limiting index below 90
We can provide PTFE membrane materials of different thicknesses and sizes to meet customer needs
