PTFE biaxially stretched film is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.
The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.
PTFE biaxially oriented film has been successfully used in a wide range of industrial fields, such as separation of special metal ions from liquid phase, industrial water treatment, plasma separation, battery separator, pharmaceutical separation, chemical product purification, drug release, Human organs, moisture-permeable and breathable materials, and the membrane market share of its products has accounted for a considerable proportion in various countries around the world.
With the continuous expansion of microporous membrane application fields and the improvement of application requirements, it can be foreseen that various microporous membrane products have great development prospects in the domestic and even international markets, and the promotion and development of new microfiltration Membrane technology and realizing the localization of products have great practical significance and economic benefits.
?Manufacturers use imported raw materials to produce materials with finer molecular weight, cleaner and better uniformity. They have a complete set of domestically advanced production lines to produce products with better quality.
