Introduction: White to slightly yellow powder, soluble in methanol and acetone, sparingly soluble in chloroform and ethyl acetate, insoluble in water, The product can exit in two different crystal modification(melting point at 200℃ and 230℃).

Applications:This product possesses the double structures of hindered phenol and acyl,and a function of anti-oxidation and metal deactivation. This product is a kind of metal deactivator, can be used either independently or together with antioxidant. It is applicable to polyethylene, polypropylene, polystyrene, polyamide, polyester, and especially to the antioxidant used in phenolic resin. It is effectively preventing the polymeric substance from self-oxidation caused by transition metal ion (the remains of the catalyst). More efficient if it is added to the polymeric substance used in insulated electric wire and cable .The perfect melting nature makes it easily to mix with and into the substance mentioned above and other polymeric substance system without any dispersing problem. The general dosage is of 0.1-0.5 share.
Storage: Product this chemical properties steady, have special to be it require. Should be damp proof and insulating against heat to store.

Packaging: cardboard boxes with plastic liners, net weight: 25Kg / box.
