Microporous insulation is a very high thermalefficiency material which has a thermal conductivity lessthan that of still air. These materials, consisting of finediameter heat resistant particles, reinforcement fibers,and high temperature radiation blockers, address the pri-mary modes of heat transfer in a novel way compared totraditional refractories.

2 These components are appropri-ately sized and configured to create a microporous struc-ture. This structure limits the number and movements ofair particles, and creates a material of exceptionally lowthermal conductivity. At elevated temperatures, the radia-tion blockers are employed to minimize radiation heattransfer by again proper sizing and materials offer benefits in industrial applica-tions including: Minimizing heat lossrelates simply to energy saving, orreheat issues. For example, steel ladles containing back-up microporous insulation have substantially less solidi-fied steel remaining in the ladle after the casting processis complete, which requires reheating. Consistency of operating temperatures may result in amore consistent final product or an easier process to reg-ulate and control.

3 Minimum space requirementsfor an equivalent tem-perature drop across the insulation component, microp-orous material may need as little as 1/4the thicknesscompared to traditional fibrous material (at elevated tem-peratures).
