Safe Vulcanisation System for Heat Resistant Natural

EV systems are those where a low level of sulphur (0 3 – 0 8 phr) and a correspondingly high level of accelerator (6 0 – 2 0 phr) are used for achieving an extremely high heat and reversion resistance in the rubber vulcanisates [1 2 3] In the CV systems the sulphur dosage is high (2 – 3 5 phr) and correspondingly the accelerator level is low (1 0 - 0 4 phr) The CV systems
