Kuken cooling tower filler is made from PVC injection molding under high pressure,it has special structure form, not only certain stiffness, but some flexibility.
Due to good elasticity, the filler would chatter under the water-drop impact effect lead to some water drop rebound to above for water redistribution. 

acidproof
alkali-resisting
anticorrosion for the organic solvent
good performance of inflaming retarding
Increasing cross-sectional area
add water retention time
