Henkel’s odd-chain EMEROX@Azelaic Acid (l-9 Nonanedioic Acid) is a natural-based, g-carbon, saturated,lOO% straight chain dibasic acid. It performs better than even-carbon dibasic acids by: ?? Improving flexibility; ?? Providing derivatives with lower melting points than even-chain acids; ?? Providing better solubility characteristics; and ?? Improving dye receptivity. Available Azelaic Acid grades: . EMEROX@ 1110 technical grade, with approximately 98% dibasic acid content, ?? EMEROX@ 1144 polymer grade, with a minimum 99.5% dibasic acid content. Applications include nylon engineering plastics and fibers; polyester fibers, films and adhesives; urethane elastomers and elastomeric fibers; lubricant basestocks; lithium complex greases; thermosetting polyester resins; epoxy flexibilizers; PVC plasticizers; and corrosion inhibitors.
