Plastic Random Packings
Plastic tower packings are made from polyethylene(PE),polypropylene(PP),reinforced polypropylene(RPP),polyvinyl chloride (PVC),chlorinated polyvinyl chloride(CPVC)and polyvinylidene fluoride(PVDF),They have a strong resistance to chemical corrosion, large void space and fluid capacity, low pressure drop, energy saving, low operation cost, light in weight and easy to be load and unload, and reusable. They are available for stripping, absorbing and washing in low temperature of 60-150C in the tower in chemical, petrochemical, alkali chloride, coal gas and environmental protection industries.
