The raw material of the clean room FFU filter membrane is granular PTFE (polytetrafluoroethylene) resin?, which is a homopolymer of polytetrafluoroethylene. It is a microporous polytetrafluoroethylene film prepared through a special biaxial stretching process. .
It can be compounded on various fabrics and substrates using special processes to become a new type of filter material.
The pore size of the membrane is small, the distribution is very uniform, and the porosity is large. Therefore, the membrane can filter all dust particles including bacteria while ensuring air circulation, thereby achieving the purpose of advanced purification and ventilation.
?Clean room FFU filter membranes are all produced using imported raw materials to ensure finer, cleaner and better uniformity of molecular weight.
PTFE filter paper has stable chemical properties, high temperature resistance, corrosion resistance, water repellency, oleophobicity, etc., close to zero smoke emission rate, operating temperature can reach -150℃-250℃, and dust removal efficiency can reach 99.99% above.
The minimum pore size of the PTFE membrane can reach 0.3um, which can capture most solid particles and liquid droplets.
Therefore, it also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids.
?The product is your ideal choice. We always win the smile of every customer with our sincere heart. We sincerely welcome friends from all walks of life at home and abroad to visit our company and negotiate business for common development.
