HDT @1.8 Mpa (264 psi)

HDT stands for Heat Deflection Temperature or Heat Distorsion Temperature. Following the ASTM D 648 (which is equivalent to the ISO 75) the HDT is the temperature at which a given polymer test bar will be bended of 0.25 mm under a given load. In the case of the HDT @ 1.8 MPa the load value is exactly 1820 kPa, which is commonly referenced as 1.8MPa (264 psi). Practically, the test bar is immerged in an oil bath that is heated in such a way that the increase of the bath temperature is continuous (usually 2°C per minute).<br> The deflection temperature is also sometimes called the 'deflection temperature under load' (DTUL). This temperature gives an estimate of the service temperature a given polymer can withstand. However this is only an estimate, and cannot predict how the final part will perform. Other settings like speed of the temperature increase or even part design will significantly influence the final thermal performance of a given part. Still, the HDT @ 1.8Mpa is often useful when predicting maximum service temperature of parts submitted to high mechanical loads.
