YINOX 1098 is recommended for use in polyamide molded articles, fibers, and films at

concentrations of 0.05-1.0% depending on the polymer type, method of incorporation,

application, and degree of stability required. It is easily dispersed into the polymer by conventional extrusion compounding techniques. The product may be incorporated during the polyamide polymerization at concentrations of 0.05-0.20% to provide protection of polymer color properties in subsequent fabrication, spinning, or finishing operations. When YINOX 1098 is incorporated prior to or during the polyamide polymerization, reaction conditions and chain terminator concentration may require adjustment to

compensate for the presence of the antioxidant. Suggested use concentrations for YINOX 1098 in polyacetals, polyesters, polyurethanes,saturated and unsaturated rubbers range from 0.05-0.5% depending on the substrate and the stability required. The product can be used in combination with other additives such as costabilizers (e.g. phosphites, thioethers, hydroxylamines, lactones), light stabilizers (e.g. ultraviolet absorbers,hindered amines), and other functional stabilizers. The effectiveness of blends of YINOX 1098 with Ciba IRGAFOS ? 168 (YINOX B 1171) or with YINOX  12 is particularly noteworthy.
