4-Biphenylol Diphenyl Phosphate CAS 17269-99-7

① Acts 4-Biphenylol diphenyl phosphate as a halogen-free flame retardant plasticizer for engineering plastics (PC/ABS, mPPO) and epoxy resins, enhancing flame resistance and thermal stability in electronic enclosures and automotive interior parts production.

② Serves 4-Biphenylol diphenyl phosphate CAS 17269-99-7 as a stabilizer and compatibility agent for PVC and polyurethane, improving processing workability and mechanical properties in wire & cable insulation and building material manufacturing.

③ Functions as a reactive flame retardant intermediate for high-performance polymers, introducing phosphorus-containing groups to boost char-forming ability and fire safety in advanced material synthesis.

Store 4-Biphenylol diphenyl phosphate CAS 17269-99-7 at 5-30℃ in sealed HDPE/amber glass drums in cool, dry, well-ventilated area, away from open fire, strong oxidants, strong acids and direct sunlight. Wear nitrile gloves, safety goggles and dust mask; avoid inhalation, skin/eye contact & ingestion (mild irritant). Reseal tightly post-use to prevent oxidation and moisture absorption. Dispose via licensed hazardous waste channels; transport as non-hazardous solid, avoid high-temp exposure, keep away from oxidants, moisture-proof packaging required.

4-Biphenylol diphenyl phosphate CAS 17269-99-7 is a low-toxic white crystalline solid with excellent thermal/hydrolytic stability, non-flammable, low volatility and no self-polymerization risk under normal storage. Biphenyl-phosphate structure provides high phosphorus content and rigid aromatic skeleton; halogen-free formulation meets environmental standards (REACH), good compatibility with various polymers, cost-effective for industrial production with stable batch quality, and it maintains material mechanical properties while imparting flame retardancy.
