PTFE bubble film is commonly known as the “King of Plastics”. It has excellent physical and chemical properties such as high and low temperature resistance, strong acid resistance, strong alkali resistance, and oxidation resistance. It has great advantages in electronics, food, medical, biological products and other industries.
Take the common ultrafiltration process as an example. The separation mechanism is mainly sieving: there are micropores on the surface of the membrane. When the fluid flows through the surface of one side of the membrane, some smaller molecules pass through the membrane with part of the solvent to the other side. , forming dialysate, while the macromolecules are trapped on the original side to form a retentate, thereby achieving the purpose of separating macromolecular solutes from small molecule solutes and solvents.
Polytetrafluoroethylene bubble point film, also known as ptfe bubble point film, is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, which is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.1μm to 0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
The polytetrafluoroethylene bubble point film 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.
