Polyether Polyols Used for sandwich panel systems for the production of polyurethane foam that ensures safe and sustainable structures with very high fire resistance and excellent thermal insulation properties.
Fire behavior of building materials and building components. Classification of fire behavior of building materials and building components. Classification of building materials
A Class: non-combustible materials
– A1 Class: without organic content,
– A2 Class: with organic content
B Class: combustible materials
– B1 Class : Flame Retardant
– B2 Class: Normal Flammability (self–extinguishing)
– B3 Class: Easily Flammable (not usable in Industrial Buildings)
The classification of polyurethane foam in a polyurethane sandwich panel is determined by the raw material used in the foaming machine when manufacturing rigid PU foam. In most countries, the PU of the Sandwich panel must pass the classification of B2.
There are two production lines for manufacturing PU sandwich panels, and the materials of Polyether Polyols Used for Sandwich Panel are different,
Continuous PU/PIR Sandwich Panel Line
Discontinuous Polyurethane Sandwich Panel Line
Areas Of Usage
Pitched Roofs
Flat Roofs
Facades
Insulation boards
Cold storage room panels
Refrigerated Containers
