CAS No. 31570-04-4 Phenolic Antioxidants ANTIOXIDANT 1098 , IRGANOX 1098

Description:

FUNDAOX 1098, a sterically hindered phenolic antioxidant, is an efficient, nondiscoloring stabilizer for organic substrates such as plastics, synthetic fibers, adhesives, and elastomers, and is particularly effective in polyamide polymers and fibers.

Applications:

FUNDAOX 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.

FUNDAOX 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.

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 FUNDAOX 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 FUNDAOX 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 FUNDAOX 1098 with FUNDAOX 168 (FUNDAOX B-1171) is particularly noteworthy. Performance data for FUNDAOX 1098 alone and in combination with other additives is available in a variety of substrates.

Competitive Advantage:

FUNDAOX 1098 provides excellent processing and long-term thermal stability as well as excellent initial resin color. The product is superior to copper-based systems used as stabilizers for polyamides with respect to color and resistance to extraction. It has excellent compatibility with polyamides and other substrates and low volatility.
