HBS is delayed action Sulphenamide Accelerator. Its produces vulcanisates of excellent quality whose
mechanical properties and ageing characteristics resemble those of boosted thiazole systems. It imparts high level
of tensile strength and modulus in rubber as compared to other sulphenamides and is thus a popular accelerator
for inner tubes. Typical dosage of Accicure HBS in rubber compounds usually varies from 0.5 – 1.5 phr although
in speciality EV systems even higher dosages are recommended.
HBS is suitable for mixes containing high loadings of reinforcing carbon blacks. Used in conjugation with RE, fast
curing yet very safe systems are obtainable.
Storage and Handling
