Properties: This product is white powder. Odorless, but bitter. Specific gravity 1.42. soluble in ethanol, acetone and ethyl acetate, insoluble in petroleum ether, dioxane, insoluble in carbon tetrachloride, benzene and water. Good storage stability, is not polluting the second antioxidant.
Uses: This product is used as an antioxidant for natural rubber, diene synthetic rubber and latex, and can also be used for polyethylene. It has protective effect against oxygen, weather aging and static aging, and can also effectively protect against copper damage and overcome the adverse effects caused by sulfur during crystallization vulcanization. This product can be used alone or well with other antioxidants (such as DNP, AP and other non-contaminating antioxidants) to obtain obvious synergistic effects. This product is easy to disperse in rubber, does not change color in sunlight, and is slightly polluting. When used alone, the dosage is generally 1-1.5 parts, when the dosage exceeds 2 parts, the phenomenon of frost will occur. The dosage in latex foam rubber is 0.5 parts. Because this crystal has bitterness, it is not suitable for use in rubber products in food contact.
Packing: 25kg plastic woven bag, paper-plastic heavy bag, kraft paper bag.
