Curing agent DTDM Chemical Name: 4-4' disulfide dimorpholine formula: C8H16N2O2S Molecular Weight: 236.27 CAS NO: 103-34-4 shape: white needle crystal. The relative density of 1.32-1.38. Soluble in benzene, carbon tetrachloride, slightly soluble in acetone, gasoline, insoluble in alcohol, ether, insoluble in water. In case of inorganic acids or inorganic alkali decomposition. Storage stable at room temperature. Non-toxic, there is fishy. Touching the skin or mucosa can cause a strong and lasting sense of spicy. Uses: It can be used as natural rubber and synthetic rubber curing agents and accelerators. FDA rubber non-blooming, no pollution, no color, easy to disperse. For efficient and semi-efficient vulcanization system resulting vulcanized rubber when good heat resistance and anti-aging properties. In the curing temperature to release active sulfur, sulfur content is 27% effective, safe operation, when used alone, slow curing, and thiazoles, thiuram and dithiocarbamate salt and used to improve cure speed. This product is especially suitable for butyl rubber, mainly used in the manufacture of tires, butyl tubes, tapes and heat-resistant rubber products, but also for asphalt highway stabilizer. Packing: 25kg plastic woven bags, paper bags coincidence, kraft paper bags. Storage: Should be stored in a cool, dry, well-ventilated place. Packaged products should avoid direct sunlight, valid for one year. Rubber vulcanizing agent DTDM in EPDM Application EPDM (EPDM) available sulfur vulcanizing agent more curing system DTDM, peroxides, quinone oxime and reactive curing resin or the like. Different curing system for vulcanized rubber crosslinks type, physical and mechanical properties will have a direct impact. Six flowers using peroxide vulcanizates have better thermal stability, but its performance is poor tear, combined with the peroxide curing agent DTDM produce higher prices, smell bad, so its application is subject to a certain extent. The sulfur vulcanization system operational safety, curing rate is moderate, comprehensive physical and mechanical properties of the curing agent DTDM good supply, is the most widely used EPDM rubber vulcanization system. But the use of sulfur vulcanization system prone products "blooming." When using DTDM as the vulcanizing agent, the vulcanization process types, DTDM will decompose to form a double bond active sulfur-based vulcanizing agent crosslinks DTDM Buying, thereby vulcanizates with good heat aging properties, and can be avoided by The amount is too high and causing products "blooming" of the problem.何顺雄 South China University of Technology, who studied systematically for EPDM DTDM curing characteristics, the cross-linking density affects the mechanical properties and thermal properties of the tiger. Sun Lijun, also systematically studied the common curing system, semi-efficient vulcanization system and an effective curing system types DTDM performance impact of aging EPDM rubber mechanical properties and heat resistance. They found through research. S = 0.5 parts in half the amount DTDM effective cure system increases, the EPDM rubber burning prolonged, with increasing amount DTDM, the mechanical properties of EPDM rubber has declined.
