Properties: White crystal (granule). The density is 1.25-1.35. Soluble in acetone, benzene, toluol, diethyl ether, ethyl acetate, hot CCl4 and hot alcohol, slightly soluble in gasoline, insoluble in kerosene and water.

 

Applications: Pre-vulcanization inhibitor. Provide predictable scorch control in most Sulphur valcanisation. Improved cost performance through marginal stock recovery, single-stage mixing, higher processing and/or curing temperatures. Activity is linear and higher than most retarders. May cause bloom above 0.5 phr. It is the anti-scorching agent for both natural and synthetic rubber.

 

Package: 25kg plastic woven bag, paper with plastic film bag, kraft paper 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.
