Description
We mix nano-scale silica materials with some additives and use dry molding technology to make a micro-porous structure of high-efficiency thermal insulation board. It has a lower thermal conductivity than still air, excellent thermal insulation performance in high temperature environment, and obvious energy saving effect.
