Polytetrafluoroethylene can be formed by compression or extrusion; it can also be made into an aqueous dispersion for coating, impregnation or fiber making. PTFE is widely used in high-temperature, corrosion-resistant materials, insulating materials, anti-adhesive coatings, etc. in the atomic energy, aerospace, electronics, electrical, chemical, machinery, instrumentation, instrumentation, construction, textile, food and other industries.
Polytetrafluoroethylene is widely used in various applications requiring acid and alkali resistance and organic solvents. It is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoic acid (PFOA), is considered to be likely to be carcinogenic.
The main role of the expanded polytetrafluoroethylene raw material belt is 100% polytetrafluoroethylene as raw material, which has a micro-elastic fiber and a network of expanded structure. The expanded polytetrafluoroethylene raw material belt has the characteristics of good toughness, high longitudinal strength and easy deformation in the transverse direction. It is ideal for sealing on discs and threads. However, it cannot be used in contact with high concentrations of oxygen or liquid oxygen.
