PVC vs. PP Cooling Tower Fill — Which Is Better for Your Application?

PVC (Polyvinyl Chloride) and PP (Polypropylene) are the two most common materials used for cooling tower fill production. PVC is known for its high thermal performance and flexibility, while PP offers superior temperature resistance and chemical durability. Choosing the right material depends on water quality, tower type, and environmental conditions.

In Japan, cooling towers in urban environments typically prefer PVC fills due to their high efficiency in moderate climates. Meanwhile, in Korea’s heavy industries and chemical plants, PP fills are favored for their resistance to harsh water conditions and higher operating temperatures. However, both markets struggle with balancing material performance and price — especially when relying on imports from Western brands.
