Durez® -ter S1049 is a homologous series of hydroxyl terminated polyester diols designed for application in polyurethanes. Durez® -ter S1049 is a fully saturated material based on aliphatic dibasic acid and mixed glycols containing some pendant alkyl groups. Polyesters in this series are low melting, soft, waxy solids, which are easily maintained in the molten state. This limited crystallinity is designed to combine processing ease with high performance in urethanes. Availability of this polyester in a broad range of molecular weights permits the formulation chemist great latitude in product development and optimalisation.Information provided by Sumitomo Bakelite High Performance Plastics (sbhpp) |
