Polyurethane is a kind of flame-retardant self-extinguishing material

Because polystyrene insulation board has excellent thermal insulation performance, it can reduce the thickness of the building’s outer protective structure and increase the indoor use area under the same thermal insulation requirements.

In addition, polyurethane foams when it burns. Its softening point can reach more than 250 degrees Celsius, and it decomposes only at higher temperatures.. Polystyrene Wholesale China CASCELL® HF Suppliers insulation board is fireproof, flame retardant and high temperature resistant. Can effectively prevent the spread of fire. Polystyrene insulation board has moisture-proof and waterproof performance.

Polyurethane is a kind of flame-retardant self-extinguishing material after adding flame retardant.Our company is a company specializing in the research and development of polystyrene insulation boards. Professional technology and high-quality services have won the love of new and old customers. Moreover, polyurethane does not generate harmful gases at high temperatures. Ash forms on the surface, and this layer of ash helps insulate the foam below.

Below we will introduce the excellent quality of polystyrene insulation board. Rigid polyurethane has a closed cell ratio of over 90%, which is a hydrophobic material and will not increase the thermal conductivity due to moisture absorption, and the wall will not see water
