Light-yellow or white Power crystals, bitterness, relative density is 1.42 g/cm3, soluble in alcohol, acetone and ethyl acetate, difficully soluble in gasoline petrol and dichloromethane, insoluble in carbon tetrachloride, benzene and water, non-toxic.

Applications:

Antioxidant MB can effectively protect the pollution of copper and deal with the bad effect of over-vulcanization. It has an acation of delay to the accelerator M, DM, TMTD, etc. There are better actions when it is used with antioxident . Change less in color, it can be used in wire, cable and transparent or color rubber products and it also can be used as heat stabilizer of polyethylene and polypropylene.

Storage:

Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.

Packing:

Coextruded paper bags lined with polyethylene film bags. Net weight 25 kg per bag.
