In the construction field, flame retardants are widely used in the production of various building materials, such as foamed plastics and insulation materials. Using flame - retardant insulation materials can improve the overall fire - resistance rating of buildings and meet national building fire - prevention standards. UV absorbers are also widely used in various building materials, including paints, plastics, and adhesives, to ensure the longevity and durability of structures exposed to sunlight.

DXFR®640 produced by Danxia New Materials contains no surfactants, so it does not affect the foaming pore size of EPS and suspension polymerization. It has no TBBPA residue and is environmentally friendly. With low free bromine residue, it does not damage the extruder and does not affect the color of the substrate. It is suitable for EPS and XPS.
