Polymer melting temperature chart
WebDSC is a useful tool for studying this phenomenon known as “physical aging”. The initial DSC heating scan of physically aged polymers commonly reveals an endothermic peak near the trailing edge of the Tg step-change. This peak is referred to as the “enthalpy of relaxation” or “enthalpic recovery” (ΔH R ). WebIn general, polyurethane can be used in the temperature range of -62°C to 93°C (-80°F to 200°F). Special formulations can extend polyurethane’s performance reach to as high as 150°C (300°F).
