HDT @0.46 Mpa (67 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 @ 0.46MPa the load value is 0.46 MPa (66 psi). Practically, the test bar is immerged in an oil bath that is heated and leads to a continuous increase of the bath temperature (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 an application. Still, HDT @ 0.46Mpa is often more accurate than HDT @ 1.8MPa. This last one being usefull when final parts are used under high mechanical loads.
