Dibromoneopentyl Glycol (CAS NO : 3296-90-0)

Dibromoneopentyl glycol (DBNPG) is a highly specialised, reactive brominated flame retardant engineered with a unique neopentyl structure that isolates its two chemically stable aliphatic bromine atoms from thermal degradation, allowing it to withstand high-temperature polymer processing without releasing corrosive byproducts. Featuring two primary hydroxyl groups, DBNPG acts as a bifunctional monomer rather than a migratory additive; it chemically integrates directly into polymer backbones during polycondensation, eliminating the risk of additive leaching while providing structural permanence and excellent ultraviolet and light stability. Predominantly utilised in the polyurethane industry to formulate Class I and Class II rigid foams for thermal insulation panels, in the electronics sector to manufacture dimensionally stable, flame-retardant unsaturated polyester and epoxy resins for printed circuit boards (PCBs), and in the automotive and aerospace industries to produce lightweight, fire-resistant thermoset composites and interior structural components that comply with stringent flame, smoke, and toxicity (FST) safety standards. As a premier global DBNPG supplier offering high-purity Dibromoneopentyl glycol, we guarantee dependable supply, consistent quality, and a robust regulatory package including complete DBNPG CoA, TDS, and seamless international logistics coordination.
