ptfe black base tape film is made of polytetrafluoroethylene as raw material, using special technology, and is calendered and extruded It is a microporous membrane made by two-way stretching and other methods. It is also a new type of polymer waterproof material.
Lower-quality waterproof and breathable membranes are made of glue and have a certain degree of breathability. However, when the temperature exceeds 45 degrees Celsius, the breathability will gradually be affected until it disappears. A preliminary judgment can be made when the two types of breathable membranes come into contact. The hot-pressed composite waterproof breathable membrane usually has the origin of hot pressing. The product does not feel sticky when pressed, while the glue-laminated product does not have hot-pressed composite points.
PTFE black base tape film is a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, calendering, extrusion, biaxial stretching and other methods. It has a microporous structure with staggered fibers, high porosity, and a pore size in the range of 0.1 μm-10 μm. It can intercept solid particles and colloidal particles in gas or liquid. The pore size is small and uniform, resulting in higher efficiency with lower resistance. This film is coated on various fabrics and substrates using a special process to become a new filter material.
It is a manufacturer of ptfe black base film environmentally friendly materials that specializes in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements.
