Properties: A little bitter taste. Specific gravity: 1.50--1.59. Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol.
Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining/ non-discolouring in " white" socks; use as a plasticiser and/ or retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT.
