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