It can be processed into a shell and tube or curved panels according to customer requirements.

In addition to ordinary calcium silicate insulation boards, we also supply high-density calcium silicate boards:

There are generally two common types of high-density calcium silicate boards: glass fiber calcium silicate board (common type) and carbon fiber calcium silicate board (high temperature type), both of which have high compressive strength and a density above 800, but the specific The density can be customized according to customer requirements. N-14 is a glass fiber high-density calcium silicate board, and N-17 is a carbon fiber high-density calcium silicate board. The glass fiber high-density calcium silicate board is the common type in the high-density calcium silicate board, and the carbon fiber is the high-temperature type, which has better thermal shock resistance.
