PTFE outdoor waterproof membrane is a new polymer waterproof and breathable material developed in recent years. In terms of raw material production and processing technology, the processing technology index of PTFE waterproof and breathable membrane raw materials is much higher than that of ordinary waterproof and breathable materials; at the same time, from the perspective of the quality of waterproof and breathable fabrics, PTFE waterproof and breathable membranes are also not available in other waterproof materials. The unique functional characteristics.
When the PTFE waterproof and breathable membrane is in the state of water vapor, because the water vapor particles are smaller than the membrane's pore size, it can be smoothly discharged through the micropores of the waterproof membrane to achieve the effect of ventilation. The water molecules are larger than the pore size of the membrane, and the surface tension of the water droplets acts in it, which can prevent the penetration of water and isolate the water from the outside so that the PTFE outdoor is waterproof membrane material has the function of waterproof and breathable. PTFE waterproof and breathable membrane can keep the human body dry and comfortable.
1. The high-temperature resistance effect is good, and the working environment temperature of the PTFE membrane can reach 250°C.
2. The low-temperature resistance effect is good, the toughness effect is good, and the PTFE waterproof and breathable membrane have high strength and mechanical toughness.
3. Good corrosion resistance, PTFE waterproof, and breathable membrane can show corrosion resistance to a large part of strong, active chemical substances and solvents and does not interact with various organic solvents.
4. The effect of high lubricity is good. PTFE membrane has good friction resistance among most waterproof and breathable solid materials.
