Nowadays, Teflon waterproof and breathable membrane materials are used in many places. It can be said that its application fields are very wide.
Compared with ordinary waterproof and breathable materials, this material has more excellent and outstanding performance, which is also unmatched by other materials.
Teflon 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.
The main advantages of Teflon waterproof and breathable membrane are as follows: 1. It has good high temperature resistance. The temperature of the working environment where the waterproof breathable membrane is used can reach 250°C.
Good low temperature resistance and good toughness.
Two: High lubrication effect, good corrosion resistance effect, ptfe waterproof breathable membrane can show resistance to most chemicals and solvents, strong acids, alkalis and various organic solvents.
