In the evolving landscape of material science, the demand for enhanced safety and fire resistance in various applications is paramount. One key chemical compound making significant contributions to this field is 2,2-Bis(bromomethyl)-1,3-propanediol, commonly known by its acronym DBNPG or as Saytex FR-1138. This highly effective reactive flame retardant is indispensable for manufacturers aiming to meet stringent fire safety standards across a diverse range of products.

DBNPG (CAS No. 3296-90-0) presents as a white powder with a molecular formula of C5H10Br2O2. Its exceptional purity, typically greater than 98.0%, combined with a high bromine content exceeding 60%, makes it a powerful agent for inhibiting combustion. The compound's melting point, consistently above 109.5°C, further underscores its thermal stability, a crucial characteristic for flame retardants integrated into materials subjected to elevated temperatures.

The versatility of DBNPG is evident in its wide array of applications. It primarily functions as a reactive flame retardant, meaning it chemically integrates into the polymer matrix rather than merely being an additive. This integration provides long-lasting fire retardant properties that are less susceptible to migration or loss over time. It is extensively used in thermosetting polyester resins, where it imparts superior flame retardancy while minimizing thermal discoloration and maintaining excellent light stability. This makes it an ideal choice for durable and aesthetically sensitive applications.

Furthermore, DBNPG is particularly well-suited for rigid polyurethane foam. Its high bromine content facilitates easy binding with polyurethane, significantly improving the foam's flame retardant rating. This is increasingly critical in industries moving towards more environmentally conscious formulations, as DBNPG is widely adopted in free-CFC foam systems, contributing to both safety and environmental responsibility. Beyond these primary uses, DBNPG finds utility in other plastic auxiliary agents, including applications in the formulation of specialized paints, lubricants, and plasticizers, contributing to the overall integrity and safety profile of these materials.

For industries seeking to procure this essential flame retardant, understanding the procurement process is key. When looking to buy DBNPG, it's vital to connect with a reliable supplier who can guarantee product quality and consistent supply. The typical packaging for DBNPG is a 25KG paper-plastic composite bag, ensuring safe and efficient transport. For competitive price inquiries, prospective buyers are encouraged to reach out directly to reputable chemical manufacturers. Whether you are looking to purchase for large-scale industrial use or specific research and development needs, a direct dialogue with a qualified supplier is the best way to secure your requirements and ensure optimal product performance and adherence to safety protocols.
