s Technological advancements by our research and development have improved the hydrolytical stability of Polyester PBT compounds. After exposing these products to 85°C, at 95% relative humidity forlSOO hours, the % retention of notched Charpy impact strength, tensile strength improved by 20% over the standard heat stabilized products. Even more significantly, the retention of ultimate elongation and tensile strength was improved by greater extend even over two fold.
