About orion engineered carbons
Orion Engineered Carbons (OEC) is one of the world’s leading suppliers of carbon black. The products advantage is demonstrated in applications like Printing, Coatings, Polymer, Material Rubber Goods, Rubber and Batteries. OEC produces a broad range of carbon blacks using five different production technologies that include high-performance specialty gas blacks, acetylene blacks, furnace blacks, lamp blacks, thermal blacks and after treatment processes to modify them. Orion operates 14 global production sites and has approximately 1,425 employees worldwide.
Reinforcing Carbon Black for Tire Treads & Mechanical Rubber Goods
CORAX® N375 is a high-performance reinforcing carbon black specifically engineered for rubber compounds requiring exceptional mechanical strength and durability. Classified as an improved amorphous carbon black, it delivers significantly enhanced abrasion resistance compared to standard grades — a critical performance parameter in applications subject to intense mechanical stress, friction, and dynamic loading.
With a CAS number of 1333-86-4, CORAX® N375 belongs to the N300 series of carbon blacks, a grade family recognized in the rubber industry for its balanced combination of reinforcement, processability, and wear performance. Its particle size and structure make it particularly effective at building strong polymer-filler networks within the rubber matrix, resulting in compounds with superior tensile strength, tear resistance, and long-term durability under demanding service conditions.
Primary applications include tire tread and subtread compounds — where abrasion resistance directly impacts tread life and rolling performance — as well as highly stressed mechanical rubber goods such as conveyor belts, industrial hoses, seals, and vibration damping components. Its performance profile makes it a preferred reinforcing filler in both passenger car and commercial vehicle tire formulations.
From a regulatory and compliance standpoint, CORAX® N375 holds registrations across all major global chemical inventories, including REACH, TSCA, AICS, DSL, IECSC, EINECS, ENCS, KECI, NZIoC, PICCS, and carries HSNO approval — ensuring seamless market access across Europe, North America, Asia-Pacific, and New Zealand. Distributed by Safic-Alcan, it is available to rubber compounders and tire manufacturers worldwide.
