Properties:
It is off white powder or granule.The density is 1.26-1.32.Soluble in Chloroform, Benzene, Alcohol. Insoluble in water, gasoline, acid/alkali with lower concentration.
Applications
Provides fast cure speed and high modulus development in NR,SBR,BR and blends. Normally used Alone or with small quantities of ultra accelerator in tire compounds or industrial rubber products. Low poison and high efficiency. Can be used to effectively replace DM/DPG system. It may give equal modulus to CBS or NOBS when used at a 10% lower level. It is regarded as standard accelerator.
