            Application

MBTS can be used as fast accelerator in NR, IR, BR, SBR, NBR and EPDM. Secondary accelerators are usually required for synthetic rubbers. Having critical curing temperature higher than MBT, MBTS can prevent premature curing and scorching.During the first stage of vulcanization, it gives a long delayed action and keeps the rubber compound soft for a long period of time. This is the most characteristic feature of MBTS. When such a delayed action is required, it is recommended to use In combination with basic accelerators such as TMTD and DPG for safe processing. Can be used in almost all types of rubber products except those in contact with food, as the rubber products after vulcanization develop bitter taste.
