Rubber chemicals are specialized additives that enhance the performance, durability, and processing of natural and synthetic rubber. They include accelerators to speed vulcanization, antioxidants and antiozonants to protect against oxygen, ozone, and heat, and curing agents like sulfur or peroxides to create cross-links in polymer chains. Plasticizers improve flexibility, fillers such as carbon black or silica add strength, and processing aids help mixing and shaping. These additives give rubber products properties like elasticity, tensile strength, weather resistance, and abrasion resistance. Used in tires, conveyor belts, seals, hoses, and footwear, they are increasingly chosen for eco-friendly and low-toxicity performance.
