How to improve the high temperature resistance of Ptfe Vent Membrane - Wuxi Sinceriend New Material Technology Co., Ltd.

The following are some methods to improve the high temperature resistance of Ptfe Vent Membrane:
1. Optimize raw materials
Select high-purity, high-performance PTFE resin as raw material. The higher the purity, the fewer impurities, and the less likely it is to have adverse reactions at high temperatures, which helps to improve the high temperature resistance of the breathable membrane. At the same time, an appropriate amount of high temperature resistant additives, such as certain ceramic powders, metal oxides, etc., can be added. These additives can form a stable high temperature resistant phase in the PTFE matrix and improve the thermal stability of the material.
2. Improve processing technology
During the production process, precisely control parameters such as processing temperature, pressure and time. For example, using appropriate sintering temperature and time, the PTFE molecules are fully crystallized to form a more stable microstructure, thereby improving its high temperature resistance. In addition, the use of a biaxial stretching process can orient the PTFE molecular chains in two directions, increase the intermolecular forces, and improve the strength and high temperature resistance of the breathable membrane.
3. Surface treatment
Surface treatment of Ptfe Vent Membrane, such as plasma treatment, chemical coating, etc. Plasma treatment can introduce some active groups on the surface of the breathable membrane, improve its surface properties, and enhance the bonding strength with other high-temperature resistant materials. Chemical coating can form a layer of high-temperature resistant protective film on the surface of the breathable membrane, isolating the influence of the external high-temperature environment on PTFE, and at the same time improving its wear resistance and corrosion resistance.
4. Composite structure design
Compound Ptfe Vent Membrane with other high-temperature resistant materials to form a multilayer structure. For example, compound with high-temperature resistant polymers such as polyimide and polyphenylene sulfide, and use the high-temperature resistance of these materials to enhance the overall high-temperature resistance of Ptfe Vent Membrane. Or compound a layer of metal foil, such as aluminum foil, copper foil, etc., on the surface of Ptfe Vent Membrane. Metal foil has good thermal conductivity and high-temperature resistance, which can quickly conduct heat away, reduce the temperature of Ptfe Vent Membrane, and thus improve its high-temperature resistance.
