Properties: Specific gravity: 1.25--1.35. Soluble in acetone, benzene, toluol, diethyl ether, ethyl acetate, hot CCl4 and hot alcohol, slightly soluble in gasoline, insoluble in derosene and water.
Application: Pre-vulcanisation inhabitor. 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.
Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag.
Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 1 years when stored under normal conditions.
