Temperature Resistance

Maximum Operating Temperatures of Plastics

There are two ways in which Maximum Operating Temperatures are quoted. One is the Intermittent Peak or spike temperature, and the other is the Continuous Use temperature.

The figures below are for continuous use, above which Plastics lose their mechanical properties at a rate closely related to the dynamic stress on the part.
