Polytetrafluoroethylene (ptfe) was first synthesized and discovered by DuPont in the late 1930s.
PTFE bubble point membrane is widely used in chemical industry, textile, papermaking, aerospace, petroleum, construction, food, medicine, machinery and marine operations.
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.
