Chemical Formula Of Rubber Auxiliaries

Where R 'is H and R is organic group; Or both R 'and R are organic groups; R 'and R can also be cycled by the accelerator M or its sodium salt, or by the accelerator DM, and cyclohexylamine (product is the accelerator CZ), dicyclohexylamine (product is the accelerator DZ), diisopropylamine (product is the accelerator DIBS), Mooline (product is the accelerator NOBS), tert-butylamine (product is NS) through different processes. Their vulcanization starts slowly, but the vulcanization speed is fast, known as a delayed rapid accelerator, mainly used in the production of large rubber products such as tires. In conventional formulations, the dosage is only two-thirds of the promoters M and DM (the usual dosage of promoters M and DM is 1 to 2 parts). In the so-called "semi-effective vulcanization" system (that is, the combination of low sulfur/high accelerator), the dosage is up to 3 to 5 parts (and 0.2 to 0.4 parts of sulfur), which can obtain good processing safety and improve the comprehensive properties of vulcanized rubber.
Thiuram is a rapid accelerator, mainly used as an auxiliary accelerator of thiazoles or sulfoamides.
Dithiocarbamate is a speeding accelerator, suitable for rapid vulcanization at room temperature, but also as an auxiliary accelerator.
