New ptfe waterproof and breathable membrane production process

Today I would like to introduce a new type of material to you, which is ptfe waterproof and breathable produced and developed by the company. membrane. Let’s take a closer look below.

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 compounding. Please note that these are not points on the non-woven fabric itself. lines, but very obvious overlapping dots. Tear open 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.

PTFE 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. on, becoming a new type of filter material. The membrane material has a small pore size, approximately 0.2-0.5μm, evenly distributed and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve advanced purification and ventilation purposes.

It is a fluorine material film manufacturer integrating production, sales and customization. The company has advanced PTFE membrane production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
