The application of CBS accelerators in the field of synthetic rubber, especially SBR (styrene-butadiene rubber), has been widely recognized. Research data shows that CBS accelerator can significantly improve the tensile strength and wear resistance of SBR rubber. CBS accelerator plays a key role in the vulcanization process. It not only shortens the vulcanization time, but also improves the physical properties of the rubber. Specific research shows that by adding 1.5phr (100 parts of rubber contains 1.5 parts of accelerator) CBS accelerator, the tensile strength of the rubber increases by 20%, while the wear resistance increases by 15%. Market research shows that SBR rubber using CBS accelerator is widely used in automobile tires, industrial products and other fields. Its excellent performance occupies an important position in the fierce market competition. By comparing the effects of different added amounts of CBS accelerator on the performance of SBR rubber, the optimal dosage can be determined to achieve the best cost performance. This provides an important reference for companies in product positioning and pricing strategies. In summary, the application effect of CBS accelerator in SBR rubber is remarkable. This not only brings higher product quality to rubber product companies, but also provides end users with more durable rubber products.
