Antioxidant 1098 Chemical Properties,Uses,Production

Characterization

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

Applications

Antioxidant 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.

Features/benefits

Antioxidant 1098 provides excellent processing and long-term thermal stability as well as excellent initial resin color. The product is superior to copperbased 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.

Description

Antioxidant 1098 is in the form of white-like white powder, with good compatibility with the material, low volatility, and little effect on the color of the material before and after aging.1.jpg

Chemical Properties

Antioxidant 1098 is one of the most used phenolic antioxidants in PA6. Methanol does not show any absorption above 250 nm. The spectrum of the Irganox 1098 solution in methanol shows a maximum of 277 nm. An extinction coefficient for Antioxidant 1098 (at 277 nm) in methanol of 3560 L mol-1 cm-1 was obtained. An extinction coefficient of Antioxidant 1098 in polyamide 6 of 3330 L mol-1 cm-1 (at 277 nm) was obtained, which is slightly lower than the determined extinction coefficient of Antioxidant 1098 in methanol[1].
