MASTERBATCH FOR RUBBER COMPOUNDINGFEATURES:
– Low concentration in final compounds,
0.1 to 0.3 phr typical
– Improved mechanical properties
– Better wet grip & abrasion resistance
– Lightweighting (formulation & design)
– Lower rolling resistance
– Reduced heat build up
– Strong increase of electrical conductivity
