ptfe waterproof and breathable membrane is a new type of polymer waterproof material. It has breathable and waterproof functions due to its microporosity and hydrophobicity. It has been widely used in medical, precision electronics, automotive lights, communications, chemical industry, and security and other industries.
The waterproof and breathable membrane has excellent waterproof performance and is tightly covered to protect the building from water vapor and rainwater erosion.
Effectively ensure the insulation effect and durability of the building, making the building more energy-saving and environmentally friendly.
Under the auspices of the National Construction Engineering Quality Supervision and Inspection Center, a thermal test was conducted on an external insulation system that uses a waterproof breathable membrane combined with hanging net plastering.
The test results show that the thermal resistance value of the waterproof breathable membrane with a three-centimeter air layer can reach 0.307, which is equivalent to twice the general air thermal resistance value of the same thickness specified in the “Civil Building Thermal Design Code GB50176”. 43% of the EPS insulation board has a remarkable thermal insulation effect.
The pore size of ptfe waterproof and breathable membrane is small and uniform, the micropore structure is stable, the porosity can reach 80%~90%, and the filtration accuracy can reach above U15 level, or even reach U17 level.
The surface filtration efficiency reaches 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
It is a ptfe waterproof and breathable membrane manufacturer that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
