The technology of waterproof and breathable membranes was first introduced from European and American countries. With the development of the times, there are many waterproof and breathable membrane products today. The one we want to talk about here is ptfe waterproof and breathable membrane.
We are a manufacturer specializing in the production of polytetrafluoroethylene membrane materials. Our company has a complete set of domestically advanced production lines. Our company can produce products according to user requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
On the surface, there are obvious pressure points on both sides of the ptfe waterproof and breathable membrane. That is because the production process is through hot pressing and compounding. Please note that it is not the dot pattern of the non-woven fabric itself, but the obvious overlapping points. Pattern.
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.
In addition, gently press the non-woven fabric and membrane with your hands. If there is a sticky feeling, you can conclude that it is adhered by hot melt glue, then this is a fake waterproof and breathable membrane.
Because the hot melt adhesive is adhered even at room temperature, the three layers of material will soon bubble and separate and peel off automatically.
The ptfe waterproof and breathable membrane materials produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of the ptfe membrane; using Production and testing instruments imported from the United States test the quality of PTFE film, and have passed international SGS testing and certification, as well as ISI testing and certification.
