Carbon Black N234 (HAF-HS)
CAS Number: 1333-86-4
Carbon Black N234 is a high-abrasion furnace (HAF-HS) carbon black with higher structure than N220 and N330, delivering superior abrasion resistance, traction, and wet grip performance in tire tread compounds. Its higher surface area and structure provide better reinforcement and improved compound stiffness compared to standard HAF grades. N234 is widely specified in passenger car tire tread formulations requiring both durability and performance.
