POLYPROPYLENE (PP) BALLS


Polypropylene balls are featured by a low weight, good mechanical characteristics and corrosion, fatigue and collisions resistance. They are resisting to heat and excellent electric insulators. They are floating into water. Additives can be added to avoid degradation phenomena causing to a long exposure at sun light (UV radiation absorption). It is a recyclable material. 

 

Applications

Low load bearings, special valves, check valves, flotage valves, fluid level indicators, carburetors, flow meters, chemical, medical and laboratory devices, blood transfusion kits.

Corrosion Resistance

Polypropylene balls are resisting into not concentrated acids, alkalis, alcohols, oils, greases and most inorganic compounds. Fair resistance in aromatic hydrocarbons, Polypropylene plastic balls are not resistant in contact with halogens. They provide corrosive phenomena even in presence of concentrated acids and oxidizing agents at high temperature.
