UsesEdit. Thiocarbanilide is commonly used as a vulcanization accelerator for rubber, and as a stabilizer for PVC and PVDC. Its use as a vulcanization accelerator was discovered by BF Goodrich chemist George Oenslager.

Thiocarbamates can be synthesised by the reaction of water or alcohols upon thiocyanates (Riemschneider thiocarbamate synthesis): RSCN + H 2 O → RSC(=O)NH 2 RSCN + R'OH → RSC(=O)NR'H. Similar reactions are seen between alcohols and thiocarbamoyl chlorides such as dimethylthiocarbamoyl chloride; as well as between thiols and cyanates.

occupational exposures in the rubber-manufacturing industry


Occupational exposures in the rubber-manufacturing industry were considered by previous IARC Working Groups in 1981 and 1987 (IARC, 1982, 1987). Since that time new data have become available, which have been incorporated in this Monograph, and taken into consideration in the present evaluation.

general properties of elastomers

General Properties of Elastomers

Brasiliensis tree, native to Brazil. After the latex is processed, natural rubber becomes an elastomer with excellent mechanical properties. Natural Rubber has a typical service temperature range between –67° F and +180° F. ADVANTAGES: Natural rubber has excellent tensile, elongation, tear resistance, resilience, and electrical insulation.

Natural rubber

Some natural rubber sources, such as gutta-percha, are composed of trans-1,4-polyisoprene, a structural isomer that has similar properties. Natural rubber is an elastomer and a thermoplastic. Once the rubber is vulcanized, it is a thermoset. Most rubber in everyday use is vulcanized to a point where it shares properties of both; i.e., if it is heated and cooled, it is degraded but not destroyed.

The Manufacturing Process of Rubber | Sciencing

Natural Rubber. Natural rubber comes from latex, a milky substance produced by rubber plants. The Pilot Products manufacturing firm says that to tap the trees, rubber workers fasten cups to the trunk, then drive a spout into the bark. Latex spurts out under pressure and can run through the spout for 4 hours.

A dithiocarbamate is a functional group in organic chemistry. It is the analog of a carbamate in which both oxygen atoms are replaced by sulfur atoms. A common example is sodium diethyldithiocarbamate. Dithiocarbamates and their derivatives are widely used in the vulcanization of rubber.
