Physicochemical properties:
This product is a widely used high-reinforcing furnace black carbon black with high structural strength, and its wear resistance is between super-wearing furnace black and high wear-resistant furnace black.
Uses: It is used for tread rubber such as heavy tires and passenger tires, as well as rubber products requiring high strength and wear resistance, such as high-strength conveyor belts and industrial rubber products.
Usage and function:
This product is suitable for all kinds of rubber, giving the rubber material good tensile strength and tear strength, and has certain conductivity, but the heat and hardness are higher.
