PTFE plastic has more excellent chemical properties and stability comparing with other type of plastic.It is the most ideal material to make up anti-corrosion and sealing capacities which nonferrous metal and various alloys couldn’t solve.

Capacity of PTFE

1.Wide using range of temperature

PTFE can be used in high and low temperature -200 ~ +250 ℃

2.Excellent chemical stability

PTFE can resist to corroson of almost all organic and inorganic compounds except elemental fluorine, chlorine trifluoride and molten alkali metal. It has become the best ideal anti corrosion material in petroleum, chemical industry atomic energy etc.

3.Excellent electrical property

PTFE dielectric strength can be high to 30KV/mm.In 0.1mm film, the dielectric strength is 100KV/mm and the dielectric strength will not change with temperature.

4.Abnormal surface non-viscosity

PTFE has specific molecular structure, small surface polarity so it has no adhesion to normal materials. Its surface energy is only 18 dyne/cm. Due to this capacity, PTFE is widely used in the fields of textile, food paper and other light industry

5.Low friction coefficient and strong self-moisture .

PTFE plastic friction coefficient is only 0.04%. It is widely usded in shipping building, machinery, aviation and textile

Pall ring is a new type if chemical tower packing.It improves the distribution of gas and liquid. It has much higher surface area than Raschig ring.

PTFE Plastic Pall Ring Properties

1.High temperature resistance

PTFE plastic pall ring’s working temperature could be 250℃

2.High separation rate

PTFE pall ring has advange of large flux, small resistance, high separation efficiency and high working flexibility. Under samoe drop pressure,Pall ring working capacity is 50% higher than Raschig and can decrease half drop pressure. Pall ring increases 20% mass transfer efficiency.

3.Low temperature resistance

PTFE Pall ring has good machinery flexibility. It has 5% extensibility even when temperature down to -196℃

4.Corrosion resistance

PTFE pall ring is inert and resistant to strong acid and alkali for most chemicals and solvents. It can be applied to most of the water and various organic solvent.

5.Climate resistance

PTFE pall ring has best aging life

6.Nonhazardous

PTFE pall ring hasn’t any poison to organisms

On benefit of all above advantage, PTFE pall ring is widely used in serious installation including separation equipment, adsorption equipment and desuction unit, atmosphere decompression unit, desulphurization system, ethylbenzene separation unit, toluene separation etc.
