Description

Bis(2-Hydroxyethyl) (6H-Dibenz[C,E][1,2]Oxaphosphorin-6-Ylmethyl)Succinate p-Oxide is a high-performance, halogen-free organophosphorus compound widely recognized for its flame-retardant properties. This product is engineered to provide exceptional thermal stability and compatibility within polymer matrices, making it a critical additive for enhancing fire safety without compromising material integrity. It is primarily sought after by manufacturers in the polymer, plastics, and textile industries for producing inherently flame-retardant materials.

Application

• As a reactive or additive flame retardant in polyurethane (PU) foams, including flexible and rigid types.
• Enhancing the fire resistance of unsaturated polyester resins (UPR) and epoxy resin systems.
• Formulation of flame-retardant coatings, adhesives, and sealants for construction and electronics.
• Production of fire-safe synthetic fibers and textiles for protective clothing and furnishings.
• Use in engineering thermoplastics and thermosets for electrical and electronic components (E&E).
• Development of halogen-free, environmentally compliant flame-retardant masterbatches and compounds.
