Plastic Polyhedral Hollow Ball – High Temperature and Chemical Resistance

Plastic polyhedral hollow ball, also called multi-aspect hollow ball or polyhedral hollow ball packing, is a new type of high efficient random packing. It is made from heat resistant and chemical stable plastic material, such as PP, PE, PVC, CPVC and RPP. It is composed of two hemispheres to form a whole ball shape. Each hemisphere surface has several half fan-shape leaves, the upper and lower leaves are staggered arranged.

This design make the polyhedral hollow ball lighter weight, small wind and flowing resistance and good hydrophilic surface.

It is widely used in the sewage treatment, vacuum distillation and desulfuration of CO₂ in power plant and other applications.
