NANO PRO™ Polypropylene Grinding Media 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.
Please note: chromatic appearance of the balls may be subject to variation.
Applications:
Low load bearings, special valves, check valves, floating 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, alcohols, oils, greases and
most inorganic compounds. Fair resistance in aromatic hydrocarbons, they are not resistant in contact with halogens. They provide corrosive phenomena even in presence of concentrated acids and oxidizing agents at high temperature.
