Polytetrafluoroethylene waterproof breathable membrane, the English abbreviation is ptfe waterproof breathable membrane. This material is known as the “King of Plastics” and its Chinese trade names are “Teflon”, “Teflon”, “Teflon”, “Teflon”, “Teflon”, etc.
It is a polymer compound made of tetrafluoroethylene and has excellent chemical stability, corrosion resistance and other characteristics.
Suzhou New Material Technology Co., Ltd. is a high-tech enterprise specializing in the research, development and production of ptfe waterproof and breathable membrane technology. The company adheres to the quality policy of “keep improving and strive for excellence” and continues to innovate in product development and production. It occupies a dominant position in the market with its unique and stable performance.
The company’s R&D center has always been committed to carrying out industry-university research cooperation on polytetrafluoroethylene film products with domestic universities and colleges. After years of painstaking research and development, it not only has strong R&D strength, complete testing methods and advanced experimental equipment, but also It has attracted a large number of outstanding technical talents and developed a series of PTFE microporous membranes and derivative products that exceed those of its domestic counterparts. The results have been fruitful and it has gradually become one of the leaders in the domestic environmental protection filtration industry.
PTFE waterproof and breathable membrane 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.
