Irganox® 1098 ED

Technical Datasheet | Supplied by BASF
Irganox® 1098 ED by BASF is a N,N’-hexane-1,6-diylbis(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionamide)). Acts as an antioxidant. Provides excellent processing and long–term thermal stability as well as excellent initial resin color. Irganox® 1098 ED is superior to copper- based with respect to color and resistance to extraction and has low volatility. It is compatible with polymers such as polyacetals, polyester, polyurethanes, polyamide, saturated and unsaturated rubbers. It is an efficient, non-discoloring stabilizer for organic substrates such as plastics, synthetic fibers and elastomers. It is especially suited for the stabilization of polyamide molded parts and films. Its recommended dosage rate in polyamide is 0.05-0.20% and in polyacetals, polyesters, polyurethanes, saturated and unsaturated rubbers is 0.05-0.5%.
