Properties: White or light yellow powder, granular. The density is 1.26-1.32. Soluble in benzene, methylene chloride, carbon tetrachloride, ethyl acetate, acetone, ethanol, dissolved gasoline, do not dissolve in water, acid, dilute alkali solution.
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.
Packaging: 25kg plastic woven bag, paper with plastic film bag, Kraft paper bag or jumbo bag
Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 1 year
Note: The product could be ultra fine powder based on customer accurate requirement.
