Product Information
DTDM 4,4′-Dithiodimorpholine Rubber Auxiliaries. It can be used as vulcanising agent and accelerator for Natural Rubber and synthetic rubber. When it is used as vulcanising agent, the active sulphur can only be decomposed under the vulcanising temperature, so it is safe to use this product and no scorching phenomenon will occur. The vulcanisation speed is slow when it is used alone, but it can be increased when it is used together with thiazoles, thiurams or dithiocarbamates and other accelerators. Although salicylic acid can promote the decomposition of the product and accelerate the speed of vulcanisation, but it can make the physical properties of vulcanised rubber decline. When it is used as accelerator, due to the high effective sulphur content of the product, the amount of sulphur can be appropriately reduced. When using this product, the rubber does not spray frost, pollution, discolouration. When used in effective and semi-effective vulcanisation system, the resultant vulcanised rubber has good heat resistance and ageing resistance.

Product Properties: White needle-like crystal. Relative density 1.32-1.38, soluble in benzene, carbon tetrachloride, slightly soluble in acetone, gasoline, insoluble in ethanol, ether, insoluble in water. Decomposed by inorganic acid or inorganic alkali. Stable storage at room temperature. Non-toxic, with fishy odour. Touching the skin or mucous membrane can cause strong and persistent pungency.
Product Usage: It can be used as vulcanising agent and accelerator for natural rubber and synthetic rubber. It is easy to be dispersed without spraying, contamination or discolouration. When used in effective and semi-effective vulcanisation system, the resultant vulcanised rubber has good heat resistance and ageing resistance. It can release active sulphur under vulcanisation temperature, the effective sulphur content is 27%, it is safe to operate, the vulcanisation speed is slow when it is used alone, it can improve the vulcanisation speed when it is used with thiazoles, thiurams and dithiocarbamates. It is especially suitable for Butyl Rubber, mainly used in the manufacture of tyres, butyl inner tubes, adhesive tapes and heat-resistant Rubber Products, also used as bitumen stabilizer for highways.
Packing: 25kg plastic woven bag, paper-plastic bag, kraft paper bag.
Storage: It should be stored in a cool, dry and well-ventilated place. Packed products should be kept out of direct sunlight, valid for 1 year.
Company information
The company's main import and export products include
(1)Petrochemicals:The chemical isolated or derived from petroleum or natural gas.Petrochemicals are everywhere and are integral to modern societies. They include plastics, fertilisers, packaging, clothing, digital devices, medical equipment, detergents, tires and many others. They are also found in many parts of the modern energy system, including solar panels, wind turbine blades, batteries, thermal insulation for buildings, and electric vehicle parts.
(2)Catalysts And Auxiliaries：A catalyst is a substance that changes the rate of reaction in a chemical reaction while its own composition and quality remain unchanged after the reaction. A catalyst that speeds up a reaction is called a positive catalyst (Positive Cata-lyst), and one that slows it down is called a negative catalyst (Negative Catalyst) or retardant. Generally speaking, catalysts are positive catalysts.
Auxiliary agent refers to the industrial and agricultural production, especially in chemical production, in order to improve the production process, improve product quality and yield, or to give the product some unique application performance, usually need to add some auxiliary chemicals. It is a large class of important auxiliary raw materials in chemical production, can give the product with special properties, improve the use of finished products; can accelerate the speed of chemical reaction, improve product yield; can save raw materials, improve processing efficiency, widely used in the chemical industry.
