Rubber auxiliary MBT

Product Information:

Specification

Typical Properties

It is yellow powder with little osmyl and taste bitter. The density is 1.42-1.52.it is soluble in ethyl acetate, ethanol, solution of NaOH and Na2CO3, insoluble in benzene, water and gasoline.Lower explosion limit is 21g/m3.

Recommended Applications

In NR compounds, MBT based vulcanization systems exhibit less reversion upon overcure than other systems. Vulcanizate obtainedwith MBT tend to have a relatively low modulus but very good aging properties.

To achieve a faster cure and a higher modulus. MBT can be boosted by the use of secondary accelerators, such as

ZBEC, ZDEC, TMTD or DPG.

For the vulcanization of EPDM or IIR rubbers, MBT is a well established component of many existing vulcanization systems. MBT also finds application in latex form cure systems. It is non-staining and non-discoloring.

Handling and Storage recommendations

Store MBT in a cool, dry, well-ventilated area, avoiding exposure of the packaged product to direct sunlight. Usually the shelf time is 24 months while the recommend use of time is within 12 months.
