ColorCom Black CB326 is recommended to be used in the tread rubber for tires of high strength, low-heated including all-terrain vehicle tires, it also fits for conveyor belts, airproof products, and other rubber products of high quality.

The rubber filled with CB326 has high stretching intensity, highly resisting avulsion, high wear resistance, and high strength. CB326 has better tensile stretch than other high abrasion furnace black (HAF), but it is weaker on the stress at definite elongation, and nearly the same stretching intensity. However, it's hard for CB326 to disperse when used in rubber, and it would lead to decrease the stretching intensity, the wear resistance intensity, and the fatigability.

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