The aim of this study was to investigate the clinical relevance of determination of the total amounts of residual accelerators in rubber gloves, using a previously described analytical procedure.
We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators. Below is a rubber accelerators list of products that we offer.
Properties Density :1.31~1.34g/cm3,Soluble in benzene, acetone, chloroform, a little soluble in alcohol, insoluble in water.. Applications Suitable for natural and synthetic rubber and latex, being a good secondary accelerator of kinds of thiazole, it is used with other accelerators to the continuous vulcanization.TMTD is regulated for use in articles in contact with food as specified under .
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a . (in the absence of accelerator). The process takes around 6 hours at 140°C . manufacture of open steam cured rubber products requiring faster onset of cure for better shape retention.
Can be used as a single tmtd accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates.

The present invention is conventional without using the sulfur and accelerator, and thus natural rubber immediately caused respectively by the presence of the latex protein promoter castle type 1 hypersensitivity and delayed type IV hypersensitivity of Health - which reduces the possibility of contact with the associated problems discloses compounds for producing thin elastic film comprising a .
WESTCO™ MBTS accelerator for rubber is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, WESTCO™ MBTS does not split off active sulfur during vulcanization. For use in natural and synthetic rubber processing.
applications for over a century. The rubber articles that are vulcanised using conventional accelerators such as tetra methyl thiuram disulphide (TMTD) are carcinogenic because of the production of nitrosamines (NA) during heating for the vulcanisation reaction. The nitrosamine producing TMTD has to be replaced with a safe accelerator.
