Process conditions of polytetrafluoroethylene microporous membrane

Polytetrafluoroethylene microporous membrane is a dense and porous film made by mechanically stretching fibers and puffing them under certain process conditions.

The membrane can have billions of micropores per square inch.

Polytetrafluoroethylene microporous membranes are generally divided into the following categories: air filtration membranes, which can be used for atmospheric dust removal, air purification, etc., and are the best filter materials for various vacuum cleaners, air filters, and purification equipment; waterproof and moisture-permeable microporous membranes Porous film, which is characterized by good windproof and warmth retention, is widely used in medical, fire-fighting, anti-virus, water-immersed clothing and outdoor sleeping bags and tents; polytetrafluoroethylene bubble-point film, this film is coated on various fabrics and On the base material, it becomes a new type of filter material. The membrane has small pore size, about 0.2-0.5μm, uniform distribution and large porosity. It can filter all dust particles including bacteria while maintaining air circulation, achieving advanced purification and For the purpose of ventilation, it is widely used in pharmaceutical, biochemical, microelectronics and laboratory consumables and other fields.

The polytetrafluoroethylene microporous membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some poles with a diameter of 0.1um-0.3um For fine particles, the filtration level can reach H13-U16.

In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.

The company’s products are widely used in various fields. The company has always implemented the purpose of “quality first, reputation first” to provide users with high-tech, high-quality, high-performance, and high-level products.
