Properties: Gray--white powder (granule) with a little odor, no poison. The density is 1.31-1.34. Soluble in benzene, boluene, chloroform, CS2, CH2CL2 acetone, ethyl acetate, hardly soluble in alcohol, insoluble in water, gasoline, acid/alkali with lower concentration.
Application: CBS is a classical delayed action type accelerator, giving good scorch safety and a fast cure rate. can be used in NR, SBR and NBR. Suitable for use in rubber compound loaded with high amount of furnace black and gives vulcanizates high modulus and high tensile strength, good resistance to ageing. Especially suited for SBR when used alone or in combination with DPG, TMTD etc. Most active sulphenamide in EPDM. As it has bitter taste, it is not recommended for use in rubber products in contact with food and mouth.
Storage: To keep the bags tightly closed in a cool, well-ventilated place at 25℃ max, to place the goods on the dry wooden shelf at a height of 20cm min. And to avoid from moisture, sunshine, light and fires. The recommended max.shelf life is one year.
