Select Accelerators for Rubbers - SpecialChem

Accelerator: An accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). Accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.
