Types and applications of polytetrafluoroethylene microporous membranes:
1. Polytetrafluoroethylene air filter membrane: with a thickness of about 0.01mm and an air permeability of 60-80L/m2.s, it has smooth surface, chemical resistance, air permeability without water permeability, high air permeability, flame retardancy, high temperature resistance, acid and alkali resistance, non-toxicity, etc. It is widely used in various industrial furnaces for smoke removal and filtration in chemical, steel, metallurgy, carbon black, power generation, cement, waste incineration, and other industries.
2. Polytetrafluoroethylene purification filter membrane: with a thickness of 0.02-0.03mm and a bubble point of ≥1kg/cm2 (5.3m/s 127Pa), it is widely used in pharmaceuticals, biochemistry, microelectronics, and laboratory consumables. It is also used for air purification in dust-free workshops, laboratories, ventilation equipment, purification equipment, medical electronics, and other industries.
3. Polytetrafluoroethylene clothing membrane: with a thickness of about 0.03-0.05mm, a moisture permeability of ≥10000g/m2.24h, and a static water pressure of ≥150kPa, it is widely used in sports clothing, cold-proof clothing, special clothing for firefighting, public security, medical care, and biohazard prevention, as well as shoes, hats, gloves, sleeping bags, tents, etc.
4. Polytetrafluoroethylene composite membrane: solvent-based PU is coated on the surface of PTFE microporous membrane using our unique technology to form a microporous film with hydrophobic and oil-repellent functions. It has the characteristics of corrosion resistance, high temperature resistance, aging resistance, high precision, and ultra-filtration, and is widely used in clothing fabrics, smoke removal and dust removal, purification and sterilization, and other fields.

PTFE Lined Tee

Polytetrafluoroethylene (PTFE), commonly known as "Plastic King", is a high molecular polymer produced by polymerizing tetrafluoroethylene monomer, with a chemical formula of (C2F4)n. It has excellent heat and cold resistance and can be used for long periods of time at -180～260ºC. This material has the characteristic of being resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristic of being resistant to high temperatures, and its friction coefficient is extremely low, so it can be used as an ideal coating for cleaning the inner layer of water pipes in addition to its lubricating function. On October 27, 2017, the International Agency for Research on Cancer of the World Health Organization released a preliminary reference list of carcinogens, and PTFE was listed in the third category of carcinogens.

It has no true melting point and slowly decomposes above 450℃, directly becoming gas. At 327℃, the mechanical strength suddenly disappears. It is insoluble in any solvent. It is not corroded by any substance except for reacting with molten alkali metals. Even if boiled in hydrofluoric acid, aqua regia, fuming sulfuric acid, or sodium hydroxide, it does not undergo any changes.
PTFE is a white, odorless, tasteless, and non-toxic powder, commonly known as "Plastic King". It has excellent chemical stability, corrosion resistance, sealing performance, high lubricity, non-stickiness, electrical insulation, and good aging resistance. It is heat-resistant and can be used at a working temperature of up to 250℃. It is also cold-resistant and has good mechanical toughness at low temperatures. Even at a temperature of -196℃, it can maintain a 5% elongation rate. It is corrosion-resistant and exhibits inertia to most chemical drugs and solvents, and can withstand strong acids, alkalis, water, and various organic solvents. It has good weather resistance and has the best aging life among plastics. It is highly lubricated and has the lowest friction coefficient among solid materials. It is non-adhesive and has the smallest surface tension among solid materials, and does not adhere to any substance. It is non-toxic and has physiological inertness, and can be implanted in the human body for a long time as an artificial blood vessel or organ without any adverse reactions.
