The plastic hollow balls, polyhedral (pp) hollow ball is conbined by two hemispheres which is composed of a a number of fan-shaped leaves . plastic hollow balls has has the advantages of high void ratio, low pressure drop, low mass transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer.It is widely used in petroleum and chemical,alkali chloride,gas and environmental protection industries with max. temperature of 150°. And plastic hollow balls can be made of PE, PP, PVC, PVDF, CPVC/
PP ( Polyhedral ) Hollow Ball specifications:
（Polypropylene material just for reference）
Material of could be PE,PP, HDPE, PVDF etc.
