MBT (M) is a 2-Mercaptobenzothiazole by Puyang Changyu Petroleum Resins. It is a major acidic curing agent for IR, NR, SBR, NBR, HR and EPD systems. It can be used with other alkaline curing agents such as CY DM and CY TMTD for higher activity. It provides medium curing speed, low curing temperature & easy dispersion in rubber. It is recommended for the manufacture of tires, various power belts, conveyor belts, belts, shoes and other industrial rubber products. MBT (M) is compatible with vulcanized rubber that offer faster cure speed & high modulus. It is also suitable to help promoting agents, such as ZBEC, ZDEC, TMTD or DPG in EPDM and butyl rubber vulcanization.

Hansen Solubility Parameters

[21.5, 14.1, 17.1]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with MBT (M). A practical determination of these HSP values would provide higher certainty.
