Irganox B 1171 Blend of tris(2,4-ditert-butylphenyl)phosphite and N,N’-hexane-1,6-diylbis(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionamide)) Ciba Antioxidants >> Phenolic Antioxidants >> Phosphite Polyamides (PA) ADHESIVE IRGANOX B1171 is a blend of hindered phenolic antioxidant and a phosphite useful for the stabilization of polyamides and other polymers. 50% IRGAFOS 168 + 50% IRGANOX 1098. IRGANOX B 1171 is especially suited for the stabilization of polyamide molded parts, fibers and films. In polyamides, IRGANOX B 1171 provides excellent processing and long(term thermal stability, excellent initial resin color, and also improves light stability. IRGANOX B 1171 is superior to copper-based sustems used as stabilizers for polyamides with respect to color and resistance extraction. The product can be used in combination with other additives such as costabilizers, light stabilizers and other functional stabilizers. Blend of hindered phenolic antioxidant and phosphite. Used in adhesives. Provides very good processing and long-term thermal stability, very good initial resin color and resistance to extraction. Improves light stability. Can be used in combination with other additives such as costabilizers, light stabilizers and other functional stabilizers.
