Using polytetrafluoroethylene (ptfe) suspended powder as raw material, it is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1μm to 0.5μm.
Generally, this film is laminated on various fabrics and substrates using special processes to become a new type of filtration PTFE bubble point membrane composite material.
During the production process, ptfe bubble point film composite materials can be optimized and combined with pressure ratio, speed ratio, operating temperature and other parameters. According to the pore-forming medium and ratio, the thickness, air permeability and moisture permeability can be achieved. and online control of void ratio to produce high-quality products with different functions and uses to meet the different needs of users.
Manufacturer’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.
And it has a full set of advanced production equipment and technology to ensure excellent production quality.
Using production and testing equipment imported from the United States to test the quality of PTFE film, it has also passed international SGS testing and certification, as well as ISI testing and certification.
