| introduction | diethyldithiocarbamate tellurium, referred to as TDEC, belongs to dithiocarbamate rapid vulcanization accelerator. it is a super accelerator with particularly high activity. it is commonly used in fast vulcanization and low-temperature vulcanization products and can be directly added into rubber without causing scorch. For example, it is used in natural rubber, EPDM rubber, butyl rubber and styrene butadiene rubber, which can not only improve its vulcanization efficiency, reduce energy consumption, but also improve the foaming uniformity and mechanical strength of products. TDEC is mainly used in seals and other industries downstream of the rubber industry, especially in high-end rubber products. |
| Origin | In 1912, the Germans Hoffman (Fritz Hofmann), Debrook (K.Delbrhck) and Baogman (M.Bogmann) discovered that dithiocarbamate can be used as a vulcanization accelerator. However, TDEC in this kind of products was also discovered and applied abroad in the early days, and the specific discovery time has not been known yet. |
| apply | as supervulcanization accelerator for natural rubber and styrene butadiene rubber. It is usually used with thiazole and sulfinamide accelerators, because it does not stain or pollute, and can also be used as a main accelerator for continuous vulcanization. Can directly add rubber without causing scorch, fast vulcanization speed, can increase tensile strength. Mainly used in the manufacture of air bags (inner tube, water tire), combined with thiuram and thiazole accelerators, which can increase the vulcanization speed. The addition amount of vulcanizing agent is 2-4%, and the addition amount of accelerator is 0.5-2%. |
| product characteristics | among all dithiocarbamate accelerators, TDEC has a long scorch resistance time. TDEC is free of contamination and does not fade. The main accelerator can be used in some continuous vulcanization applications. The addition of TDEC can reduce the Mooney viscosity of rubber, improve the fluidity of the compound and improve the processing technology. When TDEC is used to manufacture articles in contact with food, it shall refer to Class 4 regulations in BgVV XXI. TDEC is not yet regulated in FDA-food contact applications. |
| use | mainly used to manufacture airbags (inner tubes, water tires), extruded hoses, wire and cable insulation, adhesive tape and molded products, etc. |
