Application:
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.
Doesn’t produce the carcinogenic nitrosamine during the rubber vulcanization, so achieved a wide application in radial tire and green tire industry.
