ptfe waterproof breathable membrane manufacturer product process
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.
Among security products, outdoor security bolts need to pass the IP67 waterproof standard. In outdoor high-temperature environments, the gas inside the bolt will expand and contract with heat. According to The established gas law formula is pv=nRT. The volume of gas inside the gun remains unchanged. As the temperature increases, the air pressure will also increase. This causes the internal air pressure to be greater than the external air pressure. The horn is affected by the air pressure and the vibration amplitude of the diaphragm becomes smaller. , the sound becomes 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 key technical parameters of speed ratio, pressure ratio, operating temperature and other parameters, online control of air permeability, thickness and void ratio can be achieved based on the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation.
