The pure product is colorless crystal and has no odor. Easily soluble in benzene, chloroform (230g/L), acetone (80g/L), carbon disulfide and other organic solvents, slightly soluble in ether and ethanol (<10g/L), insoluble in water (30mg/L), decomposed in acid. Color is white or light yellow powder.
Applications & Uses
The rubber accelerator TMTD is an excellent second accelerator for thiazole type accelerators. It can also be used together with other accelerators as accelerators for continuous vulcanization colloidal particles. Usually, it can also be used in combination with accelerator MBT(M). The vulcanization of butyl rubber is basically similar.
The accelerator is mainly used in the manufacture of tires, inner tubes, rubber shoes, medical supplies, cables, industrial rubber products, etc. It is used as a fungicide and insecticide in agriculture, and can also be used as a lubricant additive.

Tetramethylthiuram disulfide (TMTD) is a chemical compound with the CAS number 137-26-8, molecular formula C6H12N2S4, and a molecular weight of 240.43.
Q2: What are the main physical properties of pure TMTD?
The pure product is a colorless crystal with no odor. In commercial appearance, it is a white or light yellow solid powder with a melting point of 156-158 °C and a density of 1.43.
Q3: What are the solubility characteristics of TMTD?
TMTD is easily soluble in benzene, chloroform (230g/L), acetone (80g/L), and carbon disulfide. It is slightly soluble in ether and ethanol (<10g/L), and practically insoluble in water (30mg/L).
Q4: What are the primary applications of rubber accelerator TMTD?
It serves as an excellent secondary accelerator for thiazole-type accelerators and is used in manufacturing tires, inner tubes, rubber shoes, medical supplies, cables, and industrial rubber products.
Q5: Can TMTD be used in agricultural or non-rubber applications?
Yes, besides rubber manufacturing, TMTD is utilized as a fungicide and insecticide in agriculture, and it can also serve as a lubricant additive.
Q6: What are the recommended storage conditions for TMTD?
TMTD should be stored under an inert gas environment, such as argon, to preserve its stability and prevent chemical decomposition.
