NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing material science through the provision of high-quality chemical intermediates. Central to this mission is our offering of 2,2-Bis(bromomethyl)-1,3-propanediol (DBNPG), a compound whose scientific properties make it indispensable in modern flame retardant technology. Understanding the science behind DBNPG helps elucidate its critical role in ensuring safety and performance across various industries.

DBNPG, identified by CAS 3296-90-0, is a white crystalline powder characterized by its high purity, often exceeding 98.5%. Its molecular structure (C5H8Br2O2) contains a significant percentage of bromine, approximately 60%. This bromine content is the key to its flame retardant capabilities. When a material containing DBNPG is exposed to heat or flame, the bromine atoms are released and interfere with the radical chain reactions that propagate combustion in the gas phase. This action effectively smothers the flame and prevents fire spread.

As a reactive flame retardant, DBNPG integrates chemically into the polymer matrix. This is a critical distinction from additive flame retardants. The hydroxyl groups on the DBNPG molecule can react with suitable functional groups in resins like polyesters and polyurethanes. This covalent bonding ensures that the flame retardant remains a permanent part of the material, resisting migration and leaching, which are common issues that can compromise the long-term effectiveness of additive flame retardants. This reactivity also contributes to maintaining the material's mechanical properties, as it becomes an integral part of the polymer backbone.

The impact of DBNPG on material properties extends beyond just flame resistance. Formulators often choose DBNPG for its contribution to high chemical resistance, minimal thermal discoloration, and excellent light stability. These attributes are vital for products that need to withstand harsh environmental conditions or maintain their appearance over extended periods. For instance, in the development of advanced CFC-free foam systems for polyurethane applications, DBNPG is a preferred component, enabling manufacturers to comply with environmental regulations while achieving superior fire safety performance.
