Temperature limits

Upper temperature limits for Microtherm® products

Microtherm® is a high temperature insulation that performs better than still air over its full working temperature range.

The working temperature limits that we quote for continuous exposure are defined as the maximum measured temperature at which the insulation shrinks less than 2 % in the dimensions perpendicular to the direction of pressing, in a furnace under full soak conditions according to all of ASTM C356, ISO 2477 and EN 1094-6.

This is an extremely demanding performance requirement. In most applications with single sided heating, Microtherm® may withstand higher temperatures but we will not guarantee its performance as so many different factors can have an influence.

*** Although the upper continuous exposure limit for Microtherm® Super A according to the test procedures referred to above is 1150 °C (2102 °F), in some situations it may be possible for the insulation to withstand a maximum intermittent exposure temperature of 1200 °C (2192 °F).
