Properties: Gray white powder or granule. No smell but taste bitter. The density is 1.33. Soluble in alcohol, acetone, ethyl acetate, slightly soluble in petroleum ether, CH2Cl2, insoluble in CCl4, benzene and water. Good stabilization storage ability. As second antioxidant without poison.
Application: The product can be used for natural and synthetic rubbers. As it is secondary antioxidant, ever better effects can be developed when used together with other antioxidants. Furthermore, when it is employed in case of sulfurless vulcanization higher heat resistance can be obtained, it also serves as an accelerator of CR and heat sensitizing agent for latices. It is effective not only white and light colored articles, but also for rubber products of all types. But unsuitable for food processing.
Packing: In 25kgs bag.
Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct usnlight.. The validity is 2 year.
