Applications

PUREstab 1098 is especially suited for the stabilization of polyamide molded parts, fibers, and films. Its use is also recommended in other polymers such as polyacetals, polyesters, polyurethanes, adhesives, elastomers as well as other organic substrates. is recommended for use in polyamide molded articles, fibers, and films at concentrations of 0.05% to 0.5% depending on the polymer type, method of incorporation, application, and degree of stability required.

PUREstab 1098 can also be used during polyamide polymerization in concentration range from 0.05% to 0.2% to to provide protection of polymer color properties in subsequent fabrication, spinning, or finishing operations. When PUREstab 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. It can be used in combination with other additives, such as costabilizers (e. g. phosphites, thioethers, hydroxylamines), light stabilizers (e. g. UV absorbers, hindered amines), and other functional stabilizers.
