Applications： DDA is widely used in natural rubber and synthetic rubber, instead of pollution of toxic antioxidant, for rubber antioxidant, tensile strength, elasticity and flexible performance are improved. When using in common between RD and 4010 series antiager, can produce a good synergistic effect, improve the resistance to heat aging and tear properties of rubber, applicable to the manufacture tires, rubber hose, adhesive tape, rubber shoes and latex products, and other rubber products. Can also be used in polyethylene, polyamide, polypropylene and cellulose resin non-ferrous products, also can be used for all kinds of synthetic rubber stabilizer, DDA also can be regard oil products as antioxidant, also can match into antioxidant DFC - 34 products.
Package：Galvanized steel barrel, 200 kg/barrel.
Storage：Should be stored in a cool, dry and ventilated place, and it is strictly prohibited to fireworks, storage period of validity is one year, overdue after the inspection, still can use.
