Primary accelerator for NR and SBR: 1.0-2.0phr with 2.0-3.0phr sulfur; for IIR: 0.5-1phr with 0.5-1.5 TMTD-80 and 1-2phr sulfur.
MBT is a quasi-ultrafast, multi-functional accelerator which has longer flat vulcanization period to provide excellent physical and mechanical
properties for vulcanizates. It is an anti-scorcher for sulfurless rubber compounds but a vulcanization retarder for CR compounds.
Alkaline accelerators such as aldehyde-amines and guanidines and others such as thiurams and dithiocarbamates can activate MBT.
