Polyurethane (PU) is a polymer material with excellent synthesized performance, which is widely used in various fields, including synthetic leather, textile, coatings, building materials, electronics, etc. However, PU is typically flammable, and its combustion is accompanied by heavy melting and dripping of the material, which produces hazardous fumes and gases. Therefore, the flame-retardant modification of PU has received much attention.
Alfa Chemistry provides halogen-free flame retardants for PU, which are highly efficient, environmentally friendly and characterized by low smoke, non-toxicity and non-melt droplets. Our products can produce an expanding carbon layer during combustion to achieve thermal insulation, oxygen barrier, and prevent further spread of flame on the surface.
