use:
Super accelerators for natural and synthetic rubbers and general accelerators for latex. It is especially used for butyl rubber which requires small compression deformation and nitrile rubber which requires excellent aging resistance. It is also suitable for EPDM rubber. Zinc oxide needs to be added as an active agent when used, and a small amount of stearic acid is generally required. This product is easy to disperse in rubber and is suitable for light-colored and bright-colored products. Mainly used for latex products, the general dosage in latex material is 0.3-1 part.
Physical properties:
White or light yellow powder, non-toxic and odorless. Soluble in dilute alkali, carbon disulfide, benzene, acetone and dichloromethane, slightly soluble in chloroform, insoluble in ethanol, carbon tetrachloride and ethyl acetate. Storage stability period of more than two years.
Package:
Polypropylene woven bag or kraft paper bag, lined with plastic film bag, net 25kg/bag.
