Microporous Insulation Flex

Product Description

Flamebor Flex is a relatively thinner, microporous insulation rigid panel that still has ultra-low thermal conductivity at a limited thickness. High density, good mechanical properties and compressive strength. Designed for steel mills with high compressive strength and low thermal conductivity. High density, good mechanical properties and compressive strength. Designed for steel mills with high compressive strength and low thermal conductivity.

Less than or equal to 10mm thickness, with a certain flexibility, encapsulated in aluminum foil bag, after vacuuming, the surface is clean and can be bent to a certain extent. It is mainly composed of fumed silica mixed with fiber reinforced material, which has rigidity and unity. It has very low thermal conductivity, which makes the product small thickness and light weight, which is conducive to space optimization and weight reduction. It can effectively improve the energy efficiency of the working equipment.

Flamebor Flex offers 3 application temperature models 950℃、1000℃ and 1050℃. Other demands can also be customized.
