Silica Aerogel Thermal Insulation Board

Introduction 

The common aerogel board material on the market is nano aerogel thermal insulation felt, a flexible thermal insulation material that combines aerogel in a flexible substrate through a special process.  In the past few decades, traditional thermal insulation materials have played great value in their respective fields, providing thermal insulation for the industry ,to reduce energy consumption for urban buildings. With the development of the times and the progress of science and technology, traditional insulation materials are increasingly unable to meet people's requirements for high efficiency and energy saving. So are there new thermal insulation materials to replace these traditional thermal insulation materials? That is Silica aerogel thermal insulation board.

The size of the pores of the silica aerogel insulation board is in the nanometer order, and its porosity is as high as 80-99.8%. The typical size of the pores is 1-100nm, the specific surface area is 600-1000㎡/g, and the material density can be as low as 3kg /m³.

The thermal insulation properties of aerogels are so good, precisely because aerogels have high porosity, so that the material is almost composed of long molecular chains. In this way, in the process of heat transfer, heat conduction is conducted along the molecular chain, and the heat transfer path is greatly elongated, resulting in the "infinite long path effect".

In fact, the silica aerogel insulation board also has a very obvious barrier to heat radiation and heat convection.

This comprehensive performance is the excellent thermal insulation performance of aerogel.
