In the process of forming a film from resin, the polytetrafluoroethylene microporous membrane is subjected to extrusion, biaxial stretching, heat setting, etc., and will undergo varying degrees of dissociation and orientation under the action of external forces, resulting in deformation.
Deformation causes changes in the entire structural system of the polymer. The type and size of the change are related to the properties and processing conditions of the polymer. The influencing factors include molecular weight, initial state of the polymer, stretching temperature, stretching direction, and deformation. rate and deformation size.
This change directly affects the structure and performance of the film.
The polytetrafluoroethylene microporous membranes produced are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity. We have a complete set of advanced production line equipment to ensure quality.
