The Critical Role of Chemicals in Rubber Processing: Enhancing Quality and Performance
Rubber Processing Chemicals The rubber industry relies heavily on chemicals to process natural and synthetic rubber into various usable forms. From latex to finished tires and other rubber goods, chemicals play a crucial role at every stage of rubber manufacturing and compounding. Some of the main types of rubber processing chemicals used include: Accelerators and Vulcanizing Agents One of the most important processes in rubber manufacturing is vulcanization - the chemical process that converts raw, stretchy rubber into a strong, durable material through the addition of sulfur or other curatives. Accelerators are chemicals added to control and speed up the rate of vulcanization. Common accelerators include mercaptobenzothiazole, sulfenamide and guanidine compounds. Vulcanizing agents like sulfur provide the reactivity necessary for vulcanization to occur by forming cross-links between polymer chains. Other vulcanizing agents beyond sulfur include organic peroxides and resin sys...
