PTFE gray base film is a new type of polymer material.
In terms of production technology, the technical requirements of this kind of membrane are much higher than those of ordinary materials; at the same time, in terms of quality, this membrane also has functional characteristics that other materials do not have.
Waterproof and breathable membrane (also known as Puwei waterproof and breathable membrane, PTFE membrane) is a new type of polymer waterproof material. It has breathable, waterproof and oil-proof functions due to its microporosity, hydrophobicity and oil repellency, and has been widely used. In medical, precision electronics, LED outdoor lighting, automotive lights, communications, chemical industry, security and other industries.
The crystallinity of PTFE gray base film is 55%~75%. When the temperature is greater than 327°C, the crystallization disappears and the product is completely transparent.
Because in the molecular structure of PTFE, the carbon atoms are surrounded by 4 fluorine atoms, it has a very high chemical stability and can withstand the erosion of many corrosive media, such as strong acids, strong bases, strong oxidants, grease, Ketones, ethers, alcohols, etc. have no effect on it even at high temperatures, so it has the reputation of the King of Plastics.
Widely used in chemical industry, machinery, bridges, electric power, aviation, electronics and other fields, it is one of the most ideal engineering materials in modern industrial civilization.
The ptfe gray base film produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, 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 company’s production process, and it fully complies with current environmental protection standards.
