Dankai polytetrafluoroethylene (PTFE) products are widely used, classified as follows:
1. General Materials
All kinds of rods, tubes, plates, membranes, belts, ropes, packing, gaskets, and graphite, molybdenum disulfide, aluminum oxide, glass fiber, carbon fiber as filler, to improve the pure PTFE
mechanical properties of ene.
2. Anti-corrosion
Polytetrafluoroethylene membrane is a new material with a large number of pores in the vertical and horizontal two-way stretching. It can be combined with other fabrics to make smoke solid-phase anti-corrosion filter bags or good anti-corrosion
Water-permeable, windproof and warm rain gear sportswear, cold-proof clothing, special protective clothing and light tents, pharmaceutical air compressed air, sterile filtration of various solvents and electronic industry
Filtration of high purity gases.
(1) Pipes and fittings: pure PTFE pipe; PTFE lined pipe; wrapped glass steel pipe; steel composite flange;
(2) chemical container lining: PTFE lined kettle; PTFE lined tank; PTFE lined tower;
(3) Heat exchanger;
(4) Corrugated telescopic pipe;
(5) the main parts of the valve and pump;
(6) Steel wire reinforced full pressure hose;
(7) Filter materials.
3. Sealing class
(1) Static seal: sandwich gasket; seat belt; elastic sealing belt;
(2) Dynamic seal (preparation of packing, ring seal):V-shaped seal body-used for shafts, piston rods, valves; Turbo pump seals; PTFE and rubber composite
Sealing ring; telescopic mechanical seal with bellows.

4. Load bearing category
(1) Filled PTFE bearings, used in food and chemical papermaking, textile machinery;
(2) porous copper impregnated fluorine plastic metal bearings, can be used under high temperature and high pressure dry friction, vacuum conditions;
(3) The bearing lining made of composite fabric blended with PTFE fiber and glass fiber or other fibers of PTFE fiber bearings is used for low speed and high load;
(4) Fill PTFE piston ring, guide ring, machine tool guide rail and bridge slider.
5. Insulation
(1) Class C insulation materials for wires and cables;
(2) Sheath of the stator and rotor water pipe and thermocouple of the double water internal cooling turbine generator;
(3) Microwave insulating materials for high-frequency and ultra-high-frequency communication equipment and radar;
(4) Insulating materials for printed circuit board and motor and transformer (including gas transformer);
(5) Insulating materials for air conditioners, electronic furnaces, various heaters and sulfur hexafluoride circuit breakers.
6. Anti-sticking
(1) The PTFE glass cloth coating layer on the hot roller of the sizing machine-can avoid the sticky roller phenomenon formed by the chemical slurry, and greatly improve the production rate and billet.
(2) the food industry's microwave drying conveyor belt-compared with other materials of the conveyor belt does not absorb microwave energy, non-stick because of the electricity saving, clean advantages.
(3) heat sealing sleeve anti-sticking material for polyethylene bag sealing;
(4) Anti-sticking coating-used for kitchen pots, baking molds for baking bread, frozen food storage trays, electric iron holders, and copier rollers.
7. Temperature resistance
(1) the driving device of the microwave oven, such as the coupling and roller of the microwave oven;
(2) temperature-resistant accessories of various refrigerators, air conditioners, oxygen generators and compressors;
(3) Used in the oven tray when the silicon raw material is cleaned and dried, the material is laid on the surface of the tray to avoid contact between the silicon raw material and the metal, and it can also resist high temperature, acid and alkali.
The effect.
8. Other categories
(1) the human body substitute artery, vein, heart membrane;
(2) Endoscope, forceps catheter, trachea;
(3) Other medical equipment such as tubes, bottles and filter cloths.
