Antioxidant
AO-K
AO-K is a novel multifunctional antioxidant or heat stabilizer for nylon products. By incorporating many beneficial functions into its special molecular structure, AO-K work as high efficient and long term stabilizer with low level in the nylon resin, and remain its highly reducibility even at extremely high temperature during processing and daily use. The advantages of the AO-K was confirmed by the highly stability of the pressure of nylon melt, the excellent extruding stability and the outstanding performance of nylon products. Besides, in terms of the textile industry, AO-K can prevent the broken of silk during spinning process.
