The service temperature you mentioned should refer to the glass transition temperature of plastics. The glass transition temperature refers to the temperature at which the polymer molecular chain begins to move. The macro performance is the service temperature. When the temperature is higher than the glass transition temperature, it is somewhat soft (this is the same as the concept of thin and soft materials). The service temperature of PC, PVC and PA can exceed 70 °

Long term high temperature use has a certain impact on aging resistance.
