By Liz White, UT contributing editorWarrington, UK-Solvay Caprolactones has a new caprolactone product on the market, CAPA 7203, which it says is designed for use in special elastomer applications.Made using Solyay’s propriety technology, the CAPA 7203 material is a block caproloactone polycarbonate copolymer.
