HB Chemical



Accelerators are a class of rubber chemicals which are added to a compound to increase the speed of vulcanization. The type of accelerators can be broadly classified as a primary or a secondary accelerator. This classification is based on the role they play in a given formulation, but further refined into “chemical groups” based on their functionality (example: sulfenamides vs. thiazoles). With over 50+ commonly used accelerators, let HB chemical find one that fits your use and function.
