Rubber Industry

Ultra-fine particulate fillers have been widely used as reinforcement in elastomers and all various rubber based products. The main and major fillers used in general purpose elastomers are carbon black, precipitated silica, clay , carbonates and specially precipitated calcium carbonate(PCC(  and also flame retardant fillers like  aluminium hydroxide.

Reinforcing properties of PCC

Reinforcing properties of PCC in elastomers is exemplified rather than Ground calcium carbonate and other particulate fillers.

Surface treatment of PCC

Surface treatment of PCC result in better interaction and make more compatibility between the fillers and polymer matrix and lead to improvement in final properties such ad mechanical behavior, wear and physical properties .
