Antioxidant MB refers to a specific type of antioxidant compound commonly used as a rubber additive to prevent or delay the aging process of rubber products. The "MB" in its name likely denotes a particular chemical structure or derivative—while detailed chemical information may vary, it is typically associated with 2-Mercaptobenzimidazole (also known as MBMI or MBI), which has the chemical formula C7H6N2S and a CAS number of 583-39-1.
2-Mercaptobenzimidazole functions as a sulfur-containing antioxidant, providing protection against oxidative degradation caused by heat, oxygen, and other environmental factors. It is effective in inhibiting the formation of free radicals, thereby slowing down the degradation process in rubber compounds. Antioxidant MB is especially useful in applications where rubber is exposed to high temperatures or aggressive environments that accelerate aging.
This compound is often used in the manufacturing of tires, belts, hoses, and other rubber goods where maintaining the physical properties and extending the service life of the product are crucial. Its effectiveness can be further enhanced when used in combination with other antioxidants, leveraging synergistic effects to improve overall performance.
As an antioxidant, it contributes to maintaining the flexibility, strength, and elasticity of rubber items over time, reducing the risk of cracking, hardening, or loss of function due to oxidative damage.
