Features of foamed polyurethane insulation board-1

Foamed polyurethane insulation board is one of the many types of insulation board building materials. It is mainly a high-quality building material produced by the polyurethane insulation board production line by combining polyurethane foam technology and aerosol technology. In fact, there are many kinds of insulation boards. The biggest advantage of foamed polyurethane insulation boards is the foaming characteristics. There are two processes, physical and chemical, in the production process. So, let's take a look at what are the characteristics of foamed polyurethane insulation board?

Many people know that the foamed polyurethane insulation board has fireproof, waterproof and corrosion resistance properties, but its detailed characteristics are not familiar. Let's share it with everyone here.

Product Advantages:

1. Polyurethane material has a stable porosity structure and basically a closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average life of rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. Under normal conditions of use during the life of the structure, the structure will not be damaged under dry, humid, or electrochemical corrosion, and due to external factors such as the growth of insects, fungi or algae, or the destruction of rodents.

2. Low thermal conductivity and good thermal performance

The raw material used for the insulation board is polyurethane. The density of polyurethane is greater than 35-40kg/m³, and the thermal conductivity is very low, only 0.018-0.024w/(m.k), which is the lowest thermal conductivity of the current insulation materials. Perhaps many people can hardly imagine the low thermal conductivity of foamed polyurethane insulation board. In fact, the reason for its low thermal conductivity is its polymer material. Professional production using polyurethane insulation board production line, so as to better maintain the thermal conductivity of polyurethane.

3. Moisture-proof and waterproof performance

The moisture-proof and waterproof performance of the foamed polyurethane insulation board has a closed cell rate of more than 90%, which means it will not absorb water. In actual construction applications, everyone will know that the waterproof performance of the foamed polyurethane insulation board is very good, the wall will not seep water, and will not affect the humidity of the indoor environment. It can maintain the indoor environment well and create a comfortable life for people. The waterproof advantage of foamed polyurethane insulation board is mainly due to the characteristics of its polyurethane and the high standard technology of the polyurethane insulation board production line.
