Flame Retardant Grade B
Flame Retardant Grade: Good fire resistant capability, high pre-expansion ratio and high strength of products; they are mainly applicable to thermal and cold insulation materials of buildings;
Product Details
-
High flame retardancy
The flame retardancy reaches B2 level, with an oxygen index of 30, meeting the requirements for building fire protection.
-
High foaming ratio
The high foaming ratio results in the lightest at 5g/l, making the material lighter while maintaining excellent insulation and cushioning properties, thereby enhancing the product's cost-effectiveness.
-
Wide application scope
It is widely used in building exterior wall insulation, cold chain logistics, sandwich panels and other fields, providing high-quality solutions for various industries.
