Characters:white to off-white powder (particles), the relative density of 1.29. Can be dissolved in benzene, acetone, chloroform, carbon disulfide, slightly soluble in ethanol, ether, carbon tetrachloride, insoluble in water, gasoline or dilute alkali, and water Total heat generated dimethylamine and carbon disulfide. Of the respiratory tract and skin stimulation.
Uses:TMTD in the majority of sulfur vulcanized elastomer used as a single promoter, vice accelerator and sulfur donor. TMTD scorch easily, curing speed, in the absence of an effective cure system of sulfur and sulfide produced excellent flat period, with good heat aging and resistance to compressive deformation. In the non-carbon black vulcanized rubber with good color retention. For EPDM, TMTD is a valuable associate promoter. Vulcanization process in the CR and N, N ethylene thiourea with, TMTD can be used as delay agent.
Packing:25kg plastic woven bag, Paper bag, kraft paper bags.
Storage:should be stored in a cool dry, well-ventilated place. Packaged products should avoid direct sunlight, valid for 2 years
