Occupational allergic contact dermatitis in Singapore
Chromate was mainly found as an impurity in cement in the construction industry. It was a predominant industry in Singapore in the early and mid-1980s. Personal protective equipment, like rubber gloves and boots used by construction workers, probably accounted for the high prevalence of rubber allergy among construction workers.

Rubber Compounding - an overview | ScienceDirect Topics
Accelerators of vulcanization are classified into organic and inorganic types. Organic accelerators are known to the rubber industry for over a century. Their use in rubber compounding has become universal. Some examples of organic accelerators are hexamine, mercapto-N-cyclohexyl benzothiazole sulfenamide, sodium diethyl dithiocarbamate, tetramethylthiuram disulfide, tetramethylthiuram monosulfide, etc.

Synthetic Rubber - an overview | ScienceDirect Topics
It does, however, require the use of colloids to avoid droplet coalescence. Finally, emulsion polymerization is carried out by adding the water-insoluble monomer to an aqueous solution of an emulsifier. The product is a water emulsion of polymer particles. Emulsion polymerization is used for synthetic rubber production.
