We are able to supply special formats and special thicknesses on request. We will be pleased to manufacture stampings, milled parts or cuttings according to your drawings.
The classification temperature should not be conflated with the maximum use temperature – especially if physical conditions such as tensile or pressure loads play a part. Generally, lower temperatures should be used for high temperature insulation. In these cases, our company’s engineering department will be happy to advise. Heat transfer calculations for this material can also be obtained from our engineering department.
