Polytetrafluoroethylene bubble point film, also known as ptfe bubble point film, is generally made of polytetrafluoroethylene 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.
PTFE bubble point membrane is a polymer compound of tetrafluoroethylene. It is one of the materials with the best corrosion resistance in the world. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand other chemicals. All chemical reactions are insoluble in strong acids, strong bases, and organic solutions, and do not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
? is a polytetrafluoroethylene filter membrane manufacturer specializing in R&D, production and sales.
The polytetrafluoroethylene filter membranes we produce are all imported raw materials, with high uniformity, stable performance and good air permeability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
