Dithiodimorpholine (DTDM) is a white powder with a melting point of 174-176C and a density of 1.36 g/cm3. Let's well dissolve in dichloroethane, carbon tetrachloride, chloroform, benzene, ether. Handling hazard: combustible.
N-dithiodimorpholine (DTDM) can be used alone or together with sulfur. The joint introduction of 2% DTDM by weight of rubber makes it possible to reduce the sulfur content in the rubber mixture to 0.25-0.50% by weight of rubber. The resulting rubbers are characterized by a higher resistance to aging and a lower tendency to premature vulcanization. DTDM does not change the color of rubber and does not fade, which is especially important for rubber compounds based on butyl rubber, since sulfur is poorly soluble in butyl rubber, it fades strongly, deteriorating the quality of products.
N-dithiodimorpholine (DTDM) is also used in compounds based on rubbers SKD, SKI-3, SKN. It is especially effective with sulfenamides in mixtures of SKD and SKI-3 rubbers.
Dosage in mixtures based on natural rubber with active furnace blacks 1.0 - 2.0 wt. hours, and when using N-cyclohexyl-2-benzothiazolesulfenamide 0.25 - 1.0 wt.h. In rubber compounds intended for casting, it has also become widespread in combination with thiuram and sulfenamide.
