Uses
4,4'-Dithiodimorpholine is used as a vulcanizing agent and accelerator for natural and synthetic rubber, it features heat resistance, fatigue resistance, reduction resistance, non-blooming, and scorch prevention. The resulting rubber compound is non-blooming, non-polluting, colorfast, and easily dispersed. When used in effective and semi-effective vulcanization systems, the vulcanized rubber exhibits good heat resistance and aging resistance. It releases active sulfur at vulcanization temperature, with an effective sulfur content of 27%, ensuring safe operation. While its vulcanization speed is slow when used alone, it can be increased by combining it with thiazoles, thiurams, and dithiocarbamates. It is particularly suitable for butyl rubber, primarily used in the manufacture of tires, butyl inner tubes, rubber belts, and heat-resistant rubber products. It is also used as an asphalt stabilizer for highways.
