Application of silicon raw materials cleaning and drying of the oven tray, with the material laid on the surface of the tray can be avoided to avoid the silicon raw materials in contact with the metal, but also to play a high-temperature resistant, acid and alkali effect. 1. Human body substitute arterial and venous blood vessels, heart membrane;
2. Endoscopes, clamp catheters, trachea;
3. Other tubes, bottles, filter cloth and other medical equipment.
Types and applications of PTFE microporous membrane
1. PTFE air filtration membrane: thickness of 0.01mm or so, air permeability 60-80L/m2.s, with a smooth surface, chemical resistance, air permeability, air permeability, large air permeability, flame retardant, high temperature, strong acid and alkali, non-toxic and other characteristics, are widely used in the chemical industry, iron and steel, metallurgy, carbon black, power generation, Cement, waste incineration and other industrial furnaces, such as flue gas dust removal filtration.
2. Polytetrafluoroethylene purification filtration membrane: thickness of 0.02-0.03mm, bubble point ≥ 1kg/cm2 ( 5.3m/s 127Pa), widely used in pharmaceutical, biochemical, microelectronics, and laboratory consumables and other fields; dust-free workshops, laboratories, ventilation equipment, purification equipment, medical and electronic industries such as air purification.
3. PTFE clothing film: thickness of 0.03-0.05mm or so, moisture permeability ≥ 10,000g/m2.24h, hydrostatic pressure ≧ 150kPa, widely used in sportswear, cold weather clothing, firefighting, public security, health care, anti-biochemical and other special garments; shoes, hats and gloves, as well as sleeping bags, tents and so on.
4. PTFE composite film: The solvent-based PU is applied to the surface of PTFE microporous film by our unique process to form a microporous film with hydrophilic and oil-repellent function. It has the characteristics of corrosion resistance, high temperature resistance, aging resistance, high precision and ultra-microfiltration. Widely used in clothing fabrics, smoke and dust, purification and sterilization.
