PTFE ultra-wide membrane is a microporous membrane made of polytetrafluoroethylene as raw material and formed through a special process of expansion and stretching. Nowadays, it has been used as a basic material and is used in a wide range of applications.
PTFE is a semi-crystalline polymer. Its crystals are composed of parallel-arranged folded chains to form lamellae, and then the lamellae are accumulated to form a ribbon-shaped polycrystalline polymer. There is a viscous amorphous part between the lamellae and the lamellae.
The interaction between PTFE molecular chains is weak, and the activation energy of the ribbon-like structure to form fibers is only 11.3KJ/mol, which is only several times the ambient temperature. Therefore, under the action of external stress, the ribbon-like structure can easily be pulled out of particles and become micro-particles. Fiber.
PTFE ultra-wide film is mainly produced by mechanical stretching of PTFE material.
PTFE (polytetrafluoroethylene) is a highly crystalline polymer polymerized with tetrafluoroethylene as a monomer.
It is a white waxy thermoplastic similar to polyethylene (PE).
It has excellent high temperature resistance and low temperature resistance. The melting point is 327 degrees Celsius and the decomposition temperature is 415 degrees Celsius. It can be used for a long time in the range of 200 to 260 degrees Celsius.
PTFE material is highly hydrophobic, has low surface energy, and has good non-adhesion. It is easy to remove dust accumulated on the surface of the material, so it can be rinsed with water to restore its performance, achieve reuse, and greatly extend its service life.
The ptfe ultra-wide membrane produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane; it adopts American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
