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.
The melting point of ptfe waterproof and breathable membrane is 327 degrees Celsius, the decomposition temperature is 415 degrees Celsius, and 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.
? is a fluorine material film manufacturer integrating production, sales and customization.
