luyang high temperature microporous back up hard board

Description

Microporous Hard Board

Is composed of fine powder and fibrous materials, and formed by special compressing process. The average pore size is equal to or less than the mean free path of air molecules at standard atmospheric pressure. So the board has a lower thermal conductivity than the still air, which is ideal high temperature insulation material. The Hard board has certain strength and covered by aluminum foil, PE foil.
