Polytetrafluoroethylene Products as Antiseptic Materials

Polytetrafluoroethylene Products as Antiseptic Materials

Summary

Tetrafluoroethylene products are made of PTFE resin and sintered by cold pressing of dies. They have excellent corrosion resistance, good self-lubrication and non-adhesion. Therefore, the products are almost resistant to all chemical media, and have the characteristics of wear resistance, pressure resistance, low friction coefficient and so on. It is widely used in petroleum, chemical and metallurgical machinery, transportation, medicine and food, electricity and many other fields.

Classification of PTFE

Preservative class

1. Pipeline and accessories: pure PTFE pipe; PTFE lined pipe; wrapped glass steel pipe; steel composite flange

2. Chemical container liner: PTFE liner; PTFE liner tank; PTFE liner tower;

3. Heat Exchanger

4. Corrugated telescopic tube

5. Main components of valves and pumps

6. Steel wire reinforced full pressure hose

7. Filter material. Polytetrafluoroethylene (PTFE) film is a kind of new material, which has a large number of air holes in it. When it is combined with other fabrics, it can be made into solid phase anti-corrosion filter bags of smoke and dust or good water-proof and ventilation-proof raingear sportswear, cold-proof clothes, special protective clothes and portable tents, compressed air for pharmaceuticals and various kinds of solubility. Sterile filtration of agents and filtration of high purity gases in electronic industry.

Sealing class

1. Static Sealing: Sandwich Gasket; Seating Belt; Elastic Sealing Belt;

2. Dynamic seals (compiled packing and ring seals): V-type seals - for shafts, piston rods and valves; internal seals of turbopumps; composite seals of PTFE and rubber; flexible mechanical seals with bellows.

Hollywood class

1. Filled PTFE bearings for food, chemical, paper and textile machinery

2. Porous copper impregnated fluoroplastic metal bearings can be used normally under high temperature, high pressure, dry friction and vacuum conditions.

3. Bearing liner made of PTFE fiber bearing, PTFE fiber and glass fiber or other fiber blended composite fabric, for low speed and high load;

4. Filling PTFE piston rings, guide rings, machine tool guides and Bridge sliders

Insulation class

1. Class C insulating materials for wires and cables;

2. Sheaths of stator and rotor draft pipes and thermocouples of dual-water internal-cooled turbogenerator;

3. Microwave insulation materials for high-frequency and ultra-high-frequency communication equipment and radar;

4. Printed circuit board and insulation material of motor and transformer (including gas transformer);

5. Insulation materials for air conditioners, electronic furnaces, heaters and sulfur hexafluoride circuit breakers

Anti sticking class

1. Polytetrafluoroethylene Glass Cloth Coating on Sizing Machine Hot Roller - It can avoid sticking roll phenomenon caused by chemical size, greatly improve production rate and grey cloth quality, and is insoluble in strong acid, strong alkali and organic solvents.

2. Microwave Drying Conveyor Belt in Food Industry - Compared with conveyor belts of other materials, it does not absorb microwave energy and does not stick, so it has the advantages of saving electricity and cleaning.

3. Anti-sticking material of heat-sealing sleeve for polyethylene bag sealing;

4. Anti-sticking coating - used for kitchen pots, bread baking dies, frozen food storage trays, electric iron brackets, copier rollers

Temperature tolerance

1. Driving and driving devices of microwave oven, such as coupling and roller of microwave oven;

2. Temperature-resistant fittings of refrigerators, air conditioners, oxygen generators and compressors

3. The oven tray used for drying silicon raw material after cleaning can avoid the contact between silicon raw material and metal by paving on the surface of the tray. It also has the effect of high temperature resistance and acid and alkali resistance.

Other classes

1. Substitution of human arteries, veins and membranes;

2. Endoscope, forceps, trachea;

3. Other medical devices such as tubes, bottles and filter cloth.
