Shape: this product is white powder.No smell, but bitter taste.Specific weight 1.42. Soluble in ethanol, acetone and ethyl acetate, insoluble in petroleum ether, dioxomethane, insoluble in carbon tetrachloride, benzene and water.Storage stability is good, not pollution of the second anti - aging agent.
Usage: this product is used as the antioxidant of natural rubber, diene synthetic rubber and latex. It can also be used in polyethylene.It has protective effect on oxygen, weather aging and static aging, and it can also effectively protect copper damage and overcome the adverse effect caused by excessive sulfur during crystal vulcanization.This product can be used alone or in combination with other anti-aging agents (such as DNP, AP and other non-polluting anti-aging agents) to achieve obvious synergistic effect.This product is easy to disperse in rubber, does not change color in sunlight, slightly polluting.When used alone, the dosage is generally 1-1.5 parts, when the dosage is more than 2 parts, will produce clear frost phenomenon.In latex foam rubber dosage for 0.5 parts.Because this crystal has a bitter apple, not suitable for food contact in rubber products.
Package :25kg woven plastic bag, paper plastic coincidence bag, kraft paper bag.
Storage: it should be stored in a cool, dry and well-ventilated place.Packaging products should avoid direct sunlight rabbit, valid for 2 years.
Description: this product can be made according to customer requirements for ultrafine powder.
