Outdoor lamp covers are subject to changes in ambient temperature and pressure. Temperature changes, dust, dirt and moisture will have a considerable impact on the electronic components of outdoor lighting lamps. In order to solve this problem, people have developed ptfe waterproof breathable membrane this material.
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 dots of the non-woven fabric itself, but the obvious overlapping dots. .
Tear off 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.
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%, and the fiber filament diameter can reach 0.1um-0.3um nanometer level. Therefore, the surface has a good filtration function and uses physical principles to filter particles in the air.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
The ptfe waterproof and breathable membrane produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of the ptfe membrane; it adopts American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
