In recent years, as the purification engineering industry has begun to focus on two-way acceptance standards for product quality and stability, clean room filter materials have made outstanding contributions to some high-level purification environments.

Pharmaceutical industry process water is divided into drinking water, softened water, pure water (i.e. deionized water, distilled water) and water for injection.

The water used for preparation production starts from tap water, and further adopts pure water (including deionized water and distilled water) and water for injection. More importantly, it also stipulates the cooling water for sterilization pots and sterilized products.

Usually raw water for industrial use is tap water, which is obtained by coagulation, precipitation and chlorination of natural water in water plants. However, measured by industrial standards, it still contains many impurities, mainly including dissolved inorganic and organic matter. , fine particles, colloids and microorganisms, etc.

Polytetrafluoroethylene (PTFE) material, commonly known as the “King of Plastics”, is a polymer compound polymerized by tetrafluoroethylene. It has excellent high temperature resistance, oxidation resistance, alkali resistance, hydrophobicity, and non-adhesion performance.

The clean room filter material is prepared through a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity, small and uniform pore size. Therefore, the polytetrafluoroethylene microporous membrane can be used under low resistance. Can achieve higher efficiency.
