Product Description

Specialized nanometer calcium carbonate for rubber

The RNR series nano and subnano active calcium carbonate has good compatibility with rubber, which is mainly used to fabricate tires, rubber tubes, rubber belts, oil seals, auto parts, and other rubber products.
The RNR series products can be used in the rubbers such as NR, BR and SBR, making the rubbers easy to mix, disperse, and be soft. It can improve the rubber's machinability and fluidity, and make it more smooth, more tensile, more strengthened and less permanent deformation, which have better bending and tearing strength resistances.  These products could replace or partially replace the carbon black or white carbon black, providing a good reinforcing material for the light colored rubbers.
