What kind of material is Pu board and what are its advantages?
Generally, the container houses and some logistics storage houses we see on the construction site are built with PU boards. Pu board, also known as polyurethane sandwich panel, has the advantages of beautiful atmosphere, energy saving and thermal insulation, long service life and so on. It is also a new type of energy-saving plate advocated and promoted by the state.
What material is Pu board?
Pu board, also known as polyurethane sandwich board, polyurethane composite board and polyurethane energy-saving board, is correctly referred to as polyurethane insulation sandwich panel for construction.
Pu panel is a bimetallic, single metal and non-metal composite board with polyurethane rigid foam as the insulation layer. It is usually used in the wall and roof enclosure system of industrial workshop, logistics warehouses and integrated houses.
Advantages of polyurethane sandwich panel
1. Low thermal conductivity, low thermal conductivity and good thermal insulation performance of polyurethane sandwich panel composite board, which is the best thermal insulation material.
2. Beautiful plate shape and convenient installation;
3. Polyurethane sandwich panel has good fire resistance.
4. Polyurethane sandwich board is non-toxic and tasteless.
5. Wide temperature range.
6. Waterproof and moisture proof.
Fire endurance of polyurethane sandwich panel
The combustion performance of polyurethane sandwich panel reaches grade B1 and the fire resistance is excellent. Therefore, the thickness of the wall can be reduced and the indoor usable area can be increased. Polyurethane is a kind of self extinguishing material, which is difficult to burn after adding flame retardant. Polyurethane will decompose only at high temperature, and its softening point is higher than 250 ℃.
