You need to improve your efforts to communicate. I do not know, nor will I guess which type of insulation you need to know about.

If you don't understand what the manufacturer is telling you, come back here and ask us for an explanation of the manufacturers terms.

Is it electrical, wall, pipe, thermal, vibration, or other form of insulation?
What are the operating conditions expected?
