The PTFE microporous filter membrane produced by the biaxial extension technology has a porosity of 80-95%, and the uniformity of the pore size is quite uniform. The filter area of each filter element is as high as 0.9m2. The PTFE filter element has high flow and pressure. Low difference and long service life.
Industrial filter types include PP filter, winding filter, winding filter, activated carbon filter, folding filter, membrane filter and high flow filter, absolute folding filter, metal filter, activated carbon Filter element, PP pleated filter element, winding filter element, filter bag. Each filter element uses different filter materials to ensure the chemical compatibility of various industrial fluids in the process. PTFE microporous filter membrane is one of the filter elements commonly used in the industry. The company provides diversified choices for PTFE filters.

PTFE related introduction
The PTFE membrane is made of expanded polytetrafluoroethylene (English: Polytetrafluoroethylene, abbreviated as PTFE), commonly known as "Plastic King", and the brand name Teflon (the Chinese translation of the trademark varies from place to place: Mainland China is translated into Teflon, Hong Kong is translated into special Teflon, translated as Teflon in Taiwan, and Teflon in textbooks) is made, because of its very good chemical compatibility, it is widely used in industrial filter products. PTFE can maintain good filtration characteristics in 123°C (253.4°F) autoclave sterilization or EO fumigation environment. Suitable for strong acid, strong base, organic solvent, ventilation or air filtration applications.
