     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.
