In recent years, the waterproof and breathable industry has achieved rapid growth worldwide. Driven by the rapid development of science and technology industry, ptfe waterproof and breathable membrane has also ushered in vigorous development.
In this industry, many companies are very optimistic about waterproof and breathable materials with broad development prospects, and have entered the market one after another.
People have long noticed that polytetrafluoroethylene (PTFE waterproof breathable membrane), which has the most outstanding comprehensive properties among polymer materials, has excellent high and low temperature properties, outstanding chemical stability, as well as good dielectric properties and hydrophobicity. It is an ideal membrane material for separating microparticles under some harsh conditions. However, the infusible and insoluble characteristics of PTFE make the technology of manufacturing its microfiltration membrane difficult to solve for a long time, limiting its application development.
PTFE waterproof and breathable membrane is made by 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.
It is located in Suzhou, a national high-tech industrial base, a national historical, cultural and scenic tourist city, and one of the important central cities in the Yangtze River Delta.
We have a professional polymer R&D team with strong R&D capabilities and multiple invention patent certificates and practical patent certificates.
It 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.
