Nurcacit TMTD PDR can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorch and gives fast cure rates. In sulfur less and EV cure system TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance. Good color retention is obtaining in non-black vulcanizates. TMTD is a valuable secondary accelerator for EPDM. In the vulcanization of polychloroprene rubber with N,N’-ethylene thiourea, TMTD may be used as a retarder.

Nurcacit MTT PDR used as vulcanization accelerator for chloroprene rubber, Injection-molded and technical extruded articles, profiles, hoses, seals, mills (rollers), cable sheeting, conveyor-belts based on CR. Possesses good module, age-resistance and advantageous compression set. Nurcacit MTT dispersed perfectly in compounds based on polychloroprene. As a result of its relatively low melting point (about 60 to 70 C), the material usually melts down and disperses without any problems. Because Nurcacit MTT is a powerful accelerator, it is best to incorporate it at the end of the mixing process together with ZnO. Particularly in compounds with a high rubber content, high viscosity or containing large amounts of active carbon black, MTT should be incorporated into the otherwise finished compound while it is being preheated for conversion.

Nurcacit MBTS PDR gives flat, moderately fast cures in nature and synthetic rubber. Also used in a wide range of general purpose rubbers. Non-staining/non-discoloring in “white” stock; act as a plasticizer/retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Exhibits better scorch safety than MBT.

Nurcacit TMTM PDR used as a secondary accelerator or as a booster for sulfenamides to achieve faster cure rates. TMTM is distinguished by very good processing safety in comparison with other thiurams. High curing activity and no discoloration. Unlike the thiuram dissulfides. TMTM will not produce cures in the absence of added elemental sulfur. It is an excellent accelerator for polychloroprene in association with DPG and sulpur.
