Product Description
Product Details
Introduction
KT-FR-C303 composite flame retardant for polyurethane is a nitrogen-phosphorus composite, low-smoke expansion flame retardant. After adding this product, the polyurethane coating will foam and expand on the coating surface when it is thermally cracked or burned to form a porous carbon layer. The carbon layer plays a role in heat insulation, oxygen isolation, flame retardancy and can prevent the generation of molten droplets.
When the flame retardant decomposes, it can also produce a large amount of non-combustible gas, dilute the oxygen concentration around the burning material, and play a good synergistic role with the carbon layer formed during combustion to achieve a flame retardant effect.
It also has excellent thermal stability and processing performance, and is an ideal, efficient and environmentally friendly flame retardant.
