ColorCom Black CB234 is recommended to be used in the tread rubber of tires for heavy lorries, for ordinary cars, and the rubber products required for high strength and high wear resistance.

The rubber filled with CB234 provides better wear resistance intensity than filled with CB220 and CB330, CB234 is about 10% wear resistance intensity higher than CB220, especially shows well wear resistance under strong pressure. CB234 is good process ability, glossy and flat surface after crushed, which fits for all kinds of rubbers, while it could easily get heated, and high hysteresis loss.

Packing: 20kg/Bag or 500kg/Bag with pallet.
