Teflon waterproof and breathable membrane is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. Become a new type of filter material.
The technology of waterproof and breathable membranes was first introduced from European and American countries. However, the production processes of domestic products are diverse, and the quality of products from various manufacturers is uneven, failing to form a unified quality standard.
In fact, waterproof and breathable membranes mainly consist of three layers: PP spunbond non-woven fabric, polymer breathable membrane, and PP spunbond non-woven fabric.
The main function of spunbond non-woven fabric is to enhance tensile force and hydrostatic pressure and protect the middle layer (breathable film). Real breathability mainly relies on the polymer breathable film of the middle layer.
Teflon waterproof and breathable membrane is made of polytetrafluoroethylene material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
The porosity of this membrane can reach more than 88% or even higher, and this 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℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, Teflon waterproof and breathable membranes, Teflon membranes and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
