The anti-corrosion materials, ptfe products


Tetrafluoroethylene products consists of ptfe resin, with mold after cold pressing sintering, it has excellent corrosion resistance, good self-lubrication and adhesion. So the products resistance to almost all chemical medium, and with wear-resisting, withstand voltage, low coefficient of friction properties. It is widely used in petroleum, chemical industry, metallurgy machinery, traffic in many fields such as medicine, food, electric power.

Ptfe classification

Anti-corrosion class

1. Pipes and fittings: pure ptfe tube; Ptfe lining tube; Wrap a glass steel pipe; Steel composite flange (2) chemical container liner: ptfe lining kettle; Ptfe lined with groove; Ptfe lined with tower; 3. Heat exchanger 4. Corrugated pipe 5. A major part of the valve and pump 6. Steel wire enhanced full pressure hose 7. Filter material.

Ptfe membrane through two-way stretch, there were a large number of pores, is a kind of new materials, and other fabric composite, it can be made into smoke solid-phase anticorrosive filter bag or good waterproof breathable, windproof, warm rain gear uniforms, winter coat, special protective clothing and lightweight tents, pharmaceutical, various kinds of solvents of sterile compressed air with air filter and filter of high purity gas in the electronics industry.

Seal type

1. Static seal: sandwich gasket; Take a strip; Elastic sealing strip; 2. The dynamic seal (packing, ring seals) : V -- for shaft, piston rod, valve seal body; Within the turbine pump seal; Teflon and rubber compound sealing ring; Mechanical seal with a corrugated pipe scalable.

Bearing load class

1. The filled ptfe bearing used in food chemical papermaking, textile machinery

2. The porous copper impregnated fluorine plastic metal bearing, the dry friction at high temperature and high pressure, vacuum under the conditions of normal use;

3. Ptfe fiber bearing ptfe fiber and glass fiber or other bearing liner made of fiber blended fabric, used for low speed high load;

4. The filled ptfe piston rings, oriented ring, machine tool guide rail and bridge the slider

Insulation class

1. The C level of wire and cable insulation materials; 2. The double water cooled turbo generator stator and rotor water diversion pipe and thermocouple sheath; 3. High frequency, ultra high frequency communications equipment and the radar microwave dielectric materials; 4. The printed wire board, motor and transformer transformer (including gas) insulation materials; 5. Air conditioning, electric furnace, all kinds of heater and sulfur hexafluoride circuit breaker of insulating materials

Anti-sticking class

1. The ptfe glass cloth on the sizing machine hot roll cladding - can be exempted from chemical pulp formation sticking phenomenon, greatly improve the production rate and quality of fabric, not soluble in strong acid, strong alkali and organic solvents

2. The food industry of microwave drying of conveyor belt, compared with other materials transportation with do not absorb microwave energy, not sticky, so there is power saving and clean

3. The polyethylene bag sealing of a thermal set of anti-sticking materials;

4. The anti-sticking coating -- for kitchen pot, pan baked bread, frozen food storage tray, iron on the palm, duplicator clamp roll

Temperature tolerance class

1. The microwave drive gear, such as microwave connecting shaft, roller;

2. All kinds of refrigerator, air conditioner, oxygen generator, compressor and heat-resistant parts

3. When applied to the silicon raw material drying after cleaning the oven tray, bedding in the tray with the material can avoid the silicon raw material with the metal contact surface, also can have the effect of high temperature resistant, anti acid and alkali

Other classes

1. The human body substitute heart arteries, veins, membrane;

2. The endoscope, clamp catheters, trachea

3. Other tube, bottle, filter cloth and other medical equipment.
