Description

(9,10-Dihydro-9-Oxa-10-Phosphaphenanthrene-10-Oxide) Polymer With Styrene And .Alpha.-Methyl-Styrene CAS NO 68052-54-0 is a high-performance polymeric flame retardant based on the DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide) structure. This compound is engineered to provide exceptional flame retardancy and thermal stability without compromising the mechanical properties of the host polymer matrix. It is a critical additive for formulators and manufacturers requiring halogen-free, phosphorus-based flame retardant solutions that meet stringent safety and environmental regulations. Key industries that rely on this advanced material include electronics, construction, and transportation.

Application

• Flame Retardant for Engineering Plastics: Primary use in polymers like epoxy resins, polyesters, and polyamides (nylons) for electrical and electronic components (E&E).
• Printed Circuit Board (PCB) Laminates: Imparts high thermal stability and flame resistance (meeting UL94 V-0) to epoxy-based prepregs and laminates.
• Thermoset Composites: Used in fiber-reinforced composites for automotive, aerospace, and wind energy applications requiring fire safety.
• Wire and Cable Insulation: A key additive in halogen-free flame retardant (HFFR) compounds for power and communication cables.
• Adhesives and Sealants: Enhances the fire resistance of high-performance adhesives used in construction and transportation.
• Synthetic Fibers and Textiles: Applied as a flame-retardant finish or additive for technical textiles and protective clothing.
• Polyurethane Foams: Can be incorporated into rigid or flexible PU foams to improve fire performance in insulation and seating.
