　　Properties: White or light yellow powder, non-toxic, odorless, soluble in dilute alkali, carbon disulfide, benzene, acetone and methylene chloride, slightly soluble in chloroform, insoluble in ethanol, carbon tetrachloride and ethyl acetate.

　　Uses: Super accelerator for natural rubber, synthetic rubber and general accelerator for latex. It is especially suitable for butyl rubber requiring small compression deformation and nitrile rubber requiring excellent aging resistance. It is also suitable for EPDM. When using zinc oxide as an active agent, a small amount of stearic acid is generally required. Because it is non-toxic, odorless, non-polluting, does not change color, and is easily dispersed in rubber, it is suitable for light-colored and brilliant-colored products. In the United States, PZ has been approved by the Food and Drug Administration (FDA). It has obvious effect in products such as EPDM and butyl rubber. Mainly used in latex products, the general dosage in latex materials is 0.3-1 parts.

　　Packing: composite paper bag lined with plastic film bag, net weight 25KG.
