Description of Accelerator

• Thiram is a fungicide, ectoparasiticide, and animal repellent. It is used to prevent fungal diseases in seed and crops. It is also used as an animal repellent to protect fruit trees and ornamentals from damage by rabbits, rodents and deer. It is effective against Stem gall of coriander, damping off, smut of millet, neck rot of onion, etc. Thiram has been used in the treatment of human scabies, as a sun screen and as a bactericide applied directly to the skin or incorporated into soap.

What is Tetramethylthiuram Disulfide?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Tetramethylthiuram Disulfide   which has developed particularly rapidly in recent years. Do you know about Tetramethylthiuram Disulfide?
• The official answer：Tetramethylthiuram disulfide (accelerator TMTD) is a general-purpose accelerator for natural and synthetic rubber and is also widely used in agriculture as a fungicide and seed soaking agent. Industrial synthesis mainly includes peroxide synthesis [1], air oxidation synthesis, in addition to the use of sodium hypochlorite as an oxidant, and the use of electrophoresis to synthesize accelerator TMTD processes have also been reported. The chemical book above synthesis methods generally has the disadvantage of the high cost of synthetic products. Concerning relevant literature, dimethylamine and carbon disulfide are proposed as raw materials. The process route of synthesizing accelerator TMTD with hydrogen peroxide as oxidant and water as solvent has obtained higher yield (98%) and better product quality (reaching international first-grade level), while effectively reducing the environmental pollution.

What’s the application of Tetramethylthiuram Disulfide?

• It is a broad-spectrum protective fungicide with a residual effect period of about 7d. It is mainly used to treat seeds and soil to control powdery mildew, black spike disease, and rice seedling blight of cereal crops, and can also be used for some fruit trees and vegetable diseases. If you use 50% wettable powder 500g to mix the seeds, it can control rice blast, rice, and flax leaf spot disease, barley, and wheat black spike disease. The product as a pesticide is usually called foeman, mainly used to treat seeds and soil to control gram cereal powdery mildew, black spike disease, and vegetable diseases. As a super accelerator for natural gum, synthetic gum, and latex, it is usually called accelerator TMTD, which is the representative of Tyuram vulcanization accelerator and accounts for 85% of the total products of the same kind. As a super accelerator for natural rubber, diene synthetic rubber, II, R, and EPDM, it is the one with the highest utilization rate. The vulcanization accelerator is very strong, but when no zinc oxide is present, it does not vulcanize at all. Used in the manufacture of cables, wires, tires, and other rubber products use as a super accelerator for natural rubber, synthetic rubber, and latex used as a post-activation accelerator for natural rubber, maleic rubber, butyl rubber, isoamyl rubber use for rice, wheat, tobacco, sugar beet, grapes, and other crop pest control, can be used for seed dressing, soil treatment use suitable for natural rubber, synthetic rubber, latex, and can be used as a vulcanizing agent. It is a good second accelerator of thiazole accelerator and can be used with other accelerators as an accelerator of continuous vulcanization rubber. It is used as a super vulcanization accelerator in the rubber industry, often used with thiazole accelerator, also can be used with other accelerators as an accelerator of continuous rubber. It can be used as a vulcanizing agent because free sulfur will be decomposed slowly above 100℃. The aging resistance and heat resistance of the products are very good. It is suitable for natural rubber and synthetic rubber. It is mainly used in the manufacture of tires, inner tubes, rubber shoes, cables, and other industrial products. Used as fungicide and insecticide in agriculture, also used as lubricant additive.
