  Properties: It is light yellow powder (granule) with a little osmyl and taste bitter. M.P.: 171℃ above. The density is 1.42-1.52 Soluble in ethyl acetate, ethanol, solution of NaOH and Na2C03, insoluble in benzene, water and gasoline. Good storage stability. lower explosion limit is 21g/m3

  Application: Mainly for the IR, NR, SBR, NBR, HR, and EPD system is currently a major acidic curing agent, curing with a medium speed, and other curing agents such as CY DM and CY TMTD alkaline curing agent can be achieved with higher activity, the curing temperature is low, easily dispersed in rubber, no pollution, mainly used in the manufacture of tires, various power belts, conveyor belt, belt, shoes and other industrial rubber products, but can not be used as food ingredients. MBT's use vulcanized rubber, which is relatively low modulus, but good anti-aging properties to obtain a faster cure speed and high modulus, can be used to help promote agents, such as:.. ZBEC, ZDEC, TMTD or DPG in EPDM and butyl rubber vulcanization, MBT is in many existing conventional cure system component, MBT may also be used for latex foam vulcanization system.

  Packing:25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag

  Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years.

  Warmth Notes: The product could be ultrafine powder based according to user needs.
