Study shows azelaic acid gives excellent performance in urethane elastomers. The superior performance of Emery azelaic acid over other di­ basic acids has been repeatedly demonstrated in many polymer applications. And now in an ex­ tensive study at the Polymer Institute of the University of Detroit, the excellent perform­ ance of thermoplastic urethane elastomers based on azelaic acid has been shown as compared to other commercial elastomers.

of the elastomer. And when comparing thermoplas­ tic urethane elastomers derived from poly (e-caprolactone) glycol to those derived from poly (tetra methylene azelate) glycol, the azelate was found to have greater tensile strength (both at ambient temperatures and lower tempera­ tures) and equivalent torsional flexibility at low temperatures.

Azelates superior to adipates.

The unique odd-carbon structure of Emerox® 1144 Azelaic Acid makes it an ideal polymer grade acid for use in 6/9 nylon, high performance polyester adhesives and other applications requiring the highest purity dibasic acid. Put unique Azelaic Acid in your

The azelate elastomers topped those based on adipic in tensile strength, contribution to elonga­ tion and torsional flexibility at low temperatures. In addition, the azelates made a greater con­ tribution to hydrolytic stability

Ideal for other applications too.
