Ang materyal nga makunhuran ang temperatura sa vulcanization o mubo ang oras sa vulcanization human madugangan ang compound sa goma nga gitawag nga fulcanizing accelerator {}
In addition to the binder, the promoter can activate the vulcanizing agent and accelerate the crosslinking reaction between the vulcanizing agent and the rubber molecule to shorten the vulcanization time, reduce the vulcanization temperature, increase the yield and reduce the production cost.
