Properties Its industrial product is light yellow to brown powder, the
density is 1.26~1.32g/cm3, soluble in benzene, chloroform, carbon disulfide, acetone,
methanol, alcohol, difficultly soluble in gasoline, insoluble in
water, dilute acid and dilute alkali solution.
Applications A delayed action accelerator of vulcanization for natural and
synthetic rubber. The speed of vulcanization is similar to CBS’s,
but it’s delaying is larger than the CBS. There is little pollution
and the color is changeless. It can be used as rubber products of
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.
