MBT-75

Characteristics and Applications

An general-purpose accelerator for natural and synthetic rubbers, boasting excellent dispersibility during rubber compound mixing. It delivers rapid acceleration for natural rubber and common sulfur-vulcanized synthetic rubbers, featuring short scorch time and a wide vulcanization plateau. The resulting vulcanizates have a relatively low modulus yet good aging resistance and are non-staining. Combined with thiurams, dithiocarbamates, aldamine and guanidine accelerators, it achieves faster vulcanization rate and higher modulus. It can also function as a vulcanization retarder and anti-scorch agent in neoprene rubber and sulfurless vulcanization systems. It is not suitable for manufacturing rubber articles intended for food contact. It is mainly used for rubber products such as automotive sealing strips, inner tubes and conveyor belts.
