Tyre manufacturing depends heavily on controlled and consistent vulcanization to achieve strength, durability, flexibility, and long service life of finished tyres. Rubber accelerators play a vital role in reducing curing time, improving crosslink formation, and ensuring uniform physical properties throughout the rubber compound. Without properly selected accelerators, tyres may suffer from uneven curing, poor tensile strength, reduced abrasion resistance, excessive heat build-up, and inconsistent performance on the road.
Common accelerators such as ZDBC, ZDEC, MBT, MBTS, CBS, TBBS, and TMTD are widely used in tyre formulations based on specific processing and performance requirements. Some accelerators provide fast curing characteristics, while others offer delayed action for better scorch safety during mixing and processing. The correct balance of accelerators helps tyre manufacturers achieve optimal curing speed, strong bonding, and stable compound behavior.
In addition to accelerators, chemicals like DPG, PVI, TMQ, TDQ, and Zinc Oxide are essential in improving processing stability, ageing resistance, and overall compound consistency. Reliable supply of these rubber chemicals supports smooth production operations, reduces rejection rates, and ensures predictable tyre quality across batches.
