Durez® -ter S1019 is a homologous series of hydroxyl terminated, linear polyester diols for polyurethane applications. Durez® -ter S1019 polyesters are partially aromatic and contain long chain glycol segments, which lower ester group density in the polymer backbone. Although waxy solids at room temperature, they readily melt with moderate heat and are easily handled and processed. Polyurethanes based on Durez® -ter S1019 exhibit outstanding resistance to hydrolysis, heat aging and exterior exposure. Elastomeric products derived from this polyester series possess excellent mechanical strength and high resiliency. Availability of this polyester in a broad range of molecular weights permits the formulating chemist great latitude in product development and optimization.Information provided by Sumitomo Bakelite High Performance Plastics (sbhpp) |
