What is the polyurethane fireproof grade?
Polyurethane sandwich panels are generally fire-resistant B2, can also reach the B1 level, belonging to the B-level self-extinguishing
1) thermal conductivity of low polyurethane sandwich panel composite board thermal conductivity is small, good insulation properties, is the best insulation materials.
2) panel appearance, easy to install
3) Polyurethane sandwich panel fire resistance is good
4) Polyurethane sandwich board non-toxic and tasteless
5) use a wide temperature range
6) waterproof, moisture
Polyurethane sandwich panel shape beautiful, the overall effect is good, it sets load, insulation, fire, waterproof in one, and no secondary decoration, quick and easy installation, short construction period, comprehensive benefits, and has a good price advantage, Widely used, highly potential energy efficient building envelope materials, but also the Ministry of Construction to promote and promote a new energy-saving sheet.
Polyurethane sandwich panels are architectural polyurethane insulated sandwich panels, also known as anti-leakage sandwich panels, polyurethane rigid foam insulation board, polyurethane composite panels, PU board and so on. It is a wide range of uses, great potential energy efficient building envelope materials, but also the Ministry of Construction to promote and promote a new energy-saving sheet.
The building material is polyurethane foam as a composite layer of insulation layer, mainly used for industrial kitchen, logistics warehousing, integrated housing roof, maintenance system.
Anti-leakage sandwich panel, polyurethane rigid foam insulation board, polyurethane composite board, PU board, is the polyurethane sandwich panel of the popular argument, strictly speaking, should be building polyurethane insulated sandwich panels, in line with the national standard is GB / T 23932-2009, the alternative old standard is JC / T868-2000.
Polyurethane sandwich panel bond strength of not less than 0.09MPa, sandwich panel combustion performance to B1 level, bending capacity sandwich panel deflection Lo / 200 (Lo for the distance between the seat), the sandwich plate bending load Force not less than 0.5Kn / m2. The effective width of the plate is usually 1000mm, the length can be customized.
