Carbon Black

As an indispensable addition to automobile tires, belts, vibration-control rubber, electric cable cladding, hoses, and rubber soles of shoes, etc. carbon black reinforces and strengthens the rubber used in these various products. Furthermore, carbon black is used widely as a colorant in printing ink, paints and resins. It is also used as conductivity-imparting filler.
