In recent years, various ptfe products and derivatives produced by ptfe waterproof breathable membrane manufacturer have unknowingly entered people’s lives. As a new type of functional Materials have many excellent and outstanding properties among many materials.
In security products, outdoor security guns need to pass the IP67 waterproof standard. In outdoor high-temperature environments, the gas inside the gun will expand and contract. According to the established gas law formula pv=nRT, The volume of gas inside the gun remains unchanged, and as the temperature increases, the air pressure will also increase. This will cause the internal air pressure to be greater than the external air pressure. The horn will be affected by the air pressure, and the vibration amplitude of the diaphragm will become smaller, and the sound will also become smaller.
ptfe waterproof and breathable membrane manufacturerWaterproof and breathable membrane is made of polytetrafluoroethylene material through special processes such as mixing, extrusion, extrusion, calendering and biaxial stretching. The porosity of the membrane can reach more than 88% or even higher, and the membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um. The high-efficiency filter paper has high and low temperature resistance (-200℃ -260℃), it will not age, split or discolor after long-term use and has strong weather resistance.
It is a polytetrafluoroethyleneptfe waterproof and breathable membrane manufacturer that specializes 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.
