Polypropylene Hollow Balls
Introduction:
Plastic hollow ball is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP),
reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF).
It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact,
small specific gravity, highmass transfer efficiency and so on, and the application temperature in media ranges from 60 degree C to 150 degree C.
For these reasons it is widely used in the mining industry, petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry
and environmental protection, etc.
Sizes Available:
10mm, 20mm, 25mm, 38mm, 42mm, 46mm, 55mm etc.
