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:Prevulcanisation 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 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.
