With the improvement of environmental protection concepts, PTFE composite materials are also developing in the direction of environmental protection. It is understood that with the fierce market competition, people have developed different types of filter membranes for customers to choose from, making them stand out in the market competition.
On the surface, there are obvious pressure points on both sides of the waterproof and breathable membrane. That is because the production process is through hot pressing and lamination. Please note that it is not the dot pattern of the non-woven fabric itself, but the obvious overlap. stippling. Tear open the waterproof and breathable film. First, the middle polymer layer should be a milky white and soft waterproof and breathable layer. Because it is compounded by hot pressing, there should be pressure points on this layer of film.
Polytetrafluoroethylene composite material has a fibrillar microporous structure, a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5 μm, this film is coated on various fabrics and substrates with a special process, and can become a new filter material. The membrane has small pore size, uniform distribution, and large porosity. It can filter including bacteria while maintaining air circulation. All dust particles are removed to achieve advanced purification and ventilation.
It is a polytetrafluoroethylene composite material manufacturer specializing in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the combination of key technical parameters such as speed ratio, pressure ratio, and operating temperature, the air permeability, thickness, and void ratio can be adjusted online according to the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation.
