Rubber Additives plays a crucial role in the rubber manufacturing industry. Additives are used to improve the rubber quality, heat resistance, durability, prevent degradation, oxidation, accelerate reaction for reduce energy consumption, etc. There are many important types of rubber additives such as antioxidants, activators, anti-degradants, retardants, vulcanizing agents, blowing agents, tackifiers, and other special additives. Each type have its own specialty and features. Accelerators, vulcanizing agents and antioxidants are the major types used in the rubber industry.
Vulcanizing Agents are added to initiate or speed up the process of vulcanization, which improves its mechanical properties, making it more elastic and heat-resistant. The vulcanizing agents include insoluble sulfur, peroxides, tellurium, selenium, resinous compounds, and metal oxides. Vulcanizing agents also enhances the rubber strength.
Activators / Accelerators are used to speed up the chemical reaction between the rubber and vulcanizing agents and improvs the overall vulcanization process efficiency. These additives reduce the time needed for curing. Chemicals such as zinc oxide, stearic acid, polyester resins, sulfur, and various amines are used as activators and accelerators.
Retarders slow down the vulcanization process, which is required for delayed working times are required before the rubber sets. Chemicals prevent the rubber from curling too quickly, providing more flexibility during production. These chemicals include N-(cyclohexylthio) phthalimide, sulfenamide, salicylic acid, phthalic acid, benzoic acid and modified phthalic acid.
Rubber Additives Market Overview:
Global rubber additives market is driven by Asia pacific region with large application industry and growing end use industry in the region. China accounts for around 50% of the global rubber additives market. Tire is the major application of rubber additives contributing a dominating share of the global rubber additives market. Large automotive industry in Asia Pacific and increasing EV's market in the region is pushing the demand for improved tires. Rising demand for tires is bolstering the growth of the rubber additives market globally.
Eastman Chemical Company, Lanxess AG, NOCIL Ltd., Sumitomo Chemical, Sunsine Chemicals, Yanggu Huatai and Kemai are some of the top players of rubber processing chemicals.
