1. PTFE Expanded Sheet itself has no toxic and side effects, but one of the raw materials used in the production process, perfluoroammonium ammonium (PFOA), is considered to be likely to have carcinogenic effects.

　　PTFE Expanded Sheet hydraulic seals, sealing rings, gaskets, PTFE hydraulic seals, and gaskets are made of floating convergent PTFE epoxy resin rubber and plastic products. Compared with other plastics, polytetrafluoroethylene is resistant to solvent corrosion, and it has been widely used as rubber seals and filling materials.

　　2. Polytetrafluoroethylene expansion board does not adhere - it is a small interfacial tension in solid raw materials, and does not adhere to all chemical substances. Its physical function is very small, and its frictional resistance is only 1/5 of that of high-pressure polyethylene. It is perfluorinated Key features of the carbon spray finish. And because the interaction force between the fluorine-carbon chain molecular structure is extremely low, PTFE is not sticky.

　　3. PTFE Expanded Sheet has no harmful substances - it has physiological plasticity, and it has no side effects when it is embedded in the body as artificial blood vessels and organs for a long time. Electrically functional PTFE has low relative permittivity and dielectric loss over a wide frequency range, and high breakdown field strength, surface resistivity, and electrical isolation heat resistance.
