Thermosetting polystyrene board is a very lightweight insulating material with many outstanding features and wide applications. It uses polystyrene particles as raw materials and is processed by heating and compression, so it has a high density and good thermal insulation performance. Let's introduce the relevant content of thermosetting polystyrene board.

First of all, thermosetting polystyrene board has excellent thermal insulation performance. Due to its high density and few voids, it has a low thermal conductivity coefficient and can insulate heat. Moreover, thermosetting polystyrene board also has good compressive strength and can maintain good insulation performance even when bearing weight.

Secondly, thermosetting polystyrene board has a long service life. Because its material structure is stable and not easily affected by external factors, it can be used for a long time without aging. At the same time, thermosetting polystyrene board can also resist moisture ingress and is not affected by humid environment, which further extends its service life.

In addition, thermosetting polystyrene board also has excellent flame retardant properties. When a fire occurs, thermosetting polystyrene board can play a role in heat insulation and flame retardancy, slow down the spread of fire, and provide a time window for escape. This feature makes thermosetting polystyrene board widely used in the construction industry.

In short, thermosetting polystyrene board is an insulating material with excellent performance and wide application. Its excellent thermal insulation performance, long service life and flame retardant ability make it widely used in the construction industry, power industry and other fields. In the future, with the continuous development of science and technology, it is believed that thermosetting polystyrene board will show its unique charm in more fields.
