Common Vulcanization Accelerators

Thiazoles. Thiazoles are some of the most widely used primary vulcanization accelerators. They have improved scorch safety and allow for cure at quite high temperatures with short curing time and broad vulcanization plateau. Due to their versatility, they are used for a wide variety of rubber products.

SULFUR VULCANIZATION OF NATURAL RUBBER FOR BENZOTHIAZOLE

1. Formation of MBTS from MBS. — On heating MBS at vulcanization temperatures from 140 to 180 oC, the S-N bond in the accelerator dissociates, liberating free amine and 2-mercap- tobenzothiazole (MBT) as shown below for a generic benzothiazolesulfenamide.

Vulcanization

Vulcanization (British: vulcanisation) is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other (synthetic) rubbers via various means.

Accelerant

Secondary. In vulcanization of tire compounds they are used as small addition to sulfenamides to boost the speed and state of cure. They have a very fast vulcanization speed and therefore, next to boosters in tire compounds they are used as main accelerator in EPDM compounds and in latex compounds.

VULCANIZATION ACCELERATORS

vulcanization accelerators Organic accelerators are mainly used to reduce the reaction time of rubber vulcanization or usage of vulcanizing agent and we are supplying thiuram series with very fast vulcanization speed, sulfenamide series with relatively fast speed, and guanidine series with medium speed.

Vulcanization of rubber [SubsTech]

Dr. Dmitri Kopeliovich Vulcanization of rubber is a process of improvement of the rubber elasticity and strength by heating it in the presence of sulfur, which results in three-dimensional cross-linking of the chain rubber molecules (polyisoprene) bonded to each other by sulfur atoms. There are two general types of rubber:
