Overview
Langfang Fenghan exterior wall composite polyurethane fireproof insulation board manufacturer's customers are full of praise for a series of advantages such as flexible layout. The fire retardant performance of "composite thermosetting materials" is equivalent to that of A inorganic flame retardant materials. Polyurethane rigid foam is a new type of polymer material with excellent properties such as low bulk density, low thermal conductivity, high closed cell rate, and corrosion resistance.

Polyurethane insulation boards should be widely stored in a series of cool, ventilated, and dry places, and should not be directly exposed to the sun. They can also be placed in plastic drums, and when placing them in plastic drums, they must be sealed inside to prevent air leakage or opening lids casually. Even when opening the lid, it should be sealed at all times. Regularly sealing the lid or opening it will result in a layer of different substances on the surface. When opening the lid, there is a series of water vapor in the air, all of which can reach the surface.

1. Polyurethane insulation board has high structural strength and stable physical and chemical properties, without the loose cracking of rubber powder polystyrene particle insulation mortar and the dry shrinkage cracking of closed cell perlite vitrified microsphere insulation mortar.
2. Polyurethane insulation board has good heat resistance and dimensional stability, with a safe operating temperature of up to 120 ℃, while EPS and XPS boards only have a temperature of 70 ℃; The dimensional stability is also more than twice as good as XPS boards, with a dimensional coefficient change rate of ≤ 1%.
3. Polyurethane insulation board is easy to stick with cement-based mortar, and there is good compatibility between the two. EPS and XPS boards are difficult to adhere firmly and must be treated with surface interface agents before they can be adhered. Therefore, the polyurethane insulation board has a good bonding effect and good structural stability after the system is formed.
4. Polyurethane rigid foam is not afraid of fire, and forms a flame-retardant carbonized layer after combustion, preventing further combustion of flames. EPS and XPS boards shrink and melt into liquids when exposed to fire, and cannot form a carbonized flame retardant layer, which can easily lead to the spread of fire.
