(8)Properties:Its pure product is dust color oily liquid, becomes solid in winter. Relative density: 1.05-1.1 ,its freezing point is not lower than 20 οC . It dissolve in most of the solvents, does not dissolve in water. For it is easy to freeze and melt, so it is not good for packing and transportation, so usually use the white carbon black as the carrier to adsorb it; active ingredient content is generally 70%; stable in storage. (9)Main Uses: As the super accelerator and vulcanizing agent for natural rubber and synthetic rubber; active sulfur content is 7.5%. For this product is easy to disperse and it is pollution free and no crocking, so it is usually used for producing inner tube, rubberized fabric, rubber overshoes, rubber plug, industrial product, sealing product, etc. (10)Storage: Be sealed and stored in the shady and cool, dry and well ventilated place. Avoid the sunshine. (11)Packaging: Kraft paper bags lined with plastic film packaging bags weighing 25kg.
