Pom heat deflection temperature

WebHeat deflection temperature is used to determine short-term heat resistance and is equivalent to the temperature at which a standard test bar deflects a specified distance under a load. It distinguishes between materials that are able to sustain light loads at high temperatures and those that lose their rigidity over a narrow temperature range.
