PP balls are commonly used in flow-control and water-treatment systems requiring lightweight and corrosion-resistant plastic balls.
PP balls are manufactured from polypropylene materials with low density and good chemical resistance.
Compared with metallic balls, PP balls provide lightweight performance and good corrosion resistance, making them suitable for float balls, check valves and chemical dosing applications.
PP balls also offer low water absorption and stable performance in many water-treatment and chemical environments.
PP balls provide good chemical resistance in many aqueous and mild acid/alkali environments. Chemical compatibility should be confirmed for applications involving organic solvents or elevated temperatures.
