Heat Resistance

Heat resistance is a measure of the thermal endurance of plastic materials. It describes the ability of a test specimen to retain its shape up to a specified temperature under a specified load or to deform only within specified limits at a specified test temperature.¹

The heat resistance can be determined according to various standardised test methods such as Vicat and the Heat distortion temperature.

The UL Thermoplastics Testing Center can carry out the following heat resistance tests for you.

 

Heat resistance test methods Standards
Vicat DIN ISO 306
ASTM D1525
Heat distortion temperature DIN EN ISO 75
ASTM D648
JIS K7207
