The replacement of sulfur donors The commonly used dithiodimorpholine (DTDM) and N-oxydiethylenethiocarbamoyl-N'-oxydiethylenesulfenamide (OTOS) are A secondary amine based sulphur donor crosslink system. They are usually used in semi-vulcanized systems with a small amount of sulfur, because the sulfur-donating cross-linking system has the advantages of good Sulfur-return su ne oxygen resistance. enti ɛsɛ sɛ wɔpaw akwan foforo ma wɔn su.
