DTDM is the offering body of the sulphur. It will release a percentage of 27 active sulphur in the temperature of vulcanization; It will produce a high connecting effect to the rubber, part or whole replace the sulphur, so make the active sulphur gain an ideal physical machine function. That makes up half effective structure rubber tesist not only fatigue but also oxidation. According to DTDM’s special chemical structure in the vulcanization temperature, in addition to release active sulphur, so that make the rubber produce a high connecting function, morphlinyl, which has the second amine structure feature. This kind of free radical can not only resist heat and oxygen, but also delay coking time, so that speed up vulcanization. So, DTDM has a performance of vulcanized agent ,promoter, anti oxidantand prevent coking comprehensive effect. So many rubber products manufacturers including domestic and overseas pay attention to DTDM.
