During the production process, the polytetrafluoroethylene bubble point membrane 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.
Polytetrafluoroethylene bubble-dot film is a dense, smooth and porous film made by mechanical biaxial stretching using a special process.
PTFE bubble point membrane has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is coated on various surfaces using a special process. On fabrics and substrates, it can become a new type of filter material. The membrane has small pore size, uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving the purpose of advanced purification and ventilation.
