Development status of thermal insulation materials industry

The pros and cons of thermal insulation materials are mainly determined by the thermal conductivity of the materials. The harder the heat transfer of the material (ie, the smaller the thermal conductivity), the better the thermal insulation performance. In general, the common feature of thermal insulation materials is that they are lightweight and loose. It is porous or fibrous, and conducts heat insulation by air that does not flow inside.

Insulation cotton is generally installed under the hood of a car. It is a kind of cotton product that can play a heat insulation effect. It has the characteristics of high temperature resistance, non-flammability, low thermal conductivity, etc. It is widely used in industrial insulation cotton. Fiber is produced by processing materials such as fiberglass and glass wool. Such products can be processed further, and can be combined with aluminum foil and fiberglass cloth to make it more widely used.
