Properties:
Gray white powder (granule). The density is 1.26-1.32. soluble in benzene, CS2, methyl alcohol, acetone. chloroform, alcohol, insoluble in gasoer, acid and alkali with lower concentration.
Application:
NS Provides fast cure rate and high modulus development in NR, SBR, BR and blends. Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products low poison and high efficiency. It is good back up for NOBS. Be regarded as standard accelerator. NS widely used in all sorts of rubber products and tires,especially the meridian tires. The product is an exnt delayed accelerator with more delayed action and great curing rate and other advantages.
