PTFE membrane is a thin film with a microporous structure made from polytetrafluoroethylene raw materials through a series of professional processes such as rolling, extrusion, and biaxial stretching. PTFE membrane has a fibrous microporous structure with a porosity of over 85%. There are about 1.4 billion micropores distributed on each square centimeter of the film, with diameters ranging from 0.02 micrometers to 15 micrometers. PTFE membrane also has the following characteristics:

Chemical resistance: It exhibits extremely high resistance to a wide range of chemicals, whether acidic, alkaline, or organic solvents, and can maintain stability.
High temperature resistance: able to withstand temperatures up to 260 ° C without decomposition, very suitable for use in high-temperature environments.
Low friction: With an extremely low coefficient of friction, it is an ideal choice for applications that require low friction contact surfaces.
Hydrophobicity: It has significant hydrophobicity and can effectively repel moisture, making it suitable for use in filtration systems for water and air.
Biocompatibility: It has good compatibility with biological tissues and has been widely used in the medical and biopharmaceutical industries.
High strength: Its strength is extremely high, even exceeding that of steel wires of the same diameter, demonstrating its durability and stability.
Anti aging: It has good resistance to ultraviolet rays and excellent anti-aging performance, ensuring its long-term service life.
