Melting range: 225-227℃  Ash: ≤0.1%  Volatiles: ≤0.5% Physical Properties: white crystal  powder  Assay: ≥98%

Chemical name:

N,N`-Bis(3-(3,5-di-tert-butyl-4-hydroxyle-phenyl)propionyl)hydrazine

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

Applications: The product possesses the double structures of hindered phenol and acyl, and a function of anti-oxidation and metal deactivation. It 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. This product is effectively preventing the polymeric substance from self-oxidation caused by transition metalion(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 into the substance mentioned above and other polymeric substance system without any dispersing problem. The general dosage is of 01-0.5share. In polyolefin filled with TALC, it can be used as an effective stabilizer for processing and final use.As an effective anti-extraction stabilizer in the finished product(synthetic or natural rubber latex), especially in the NBR fuel and gasoline hoses.
