In the demanding world of materials science, the need for effective flame retardants is paramount, particularly in polymers used across various industries. Polymers are ubiquitous, forming the backbone of countless products from textiles to building materials and transportation components. However, their inherent flammability presents a significant safety challenge. This has driven continuous innovation in the field of flame retardancy, seeking solutions that are not only effective but also offer improved environmental profiles and performance characteristics. While traditional flame retardants have served their purpose, the evolving landscape of material requirements, stricter safety regulations, and increasing environmental consciousness necessitate the development of advanced alternatives.

NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-quality chemical solutions, including advanced flame retardants designed to meet these modern challenges. We understand that fire safety is not just a regulatory requirement but a fundamental aspect of product design and public protection. Our commitment is to provide materials that contribute to safer products without compromising on performance or sustainability goals. Among our portfolio, a noteworthy product gaining recognition for its unique capabilities is the DDP flame retardant.

DDP (Chemical name: [(6-Oxido-6H-dibenz[c,e][1,2]oxaphosphorin-6-yl)methyl]butanedioic acid) represents a significant step forward in flame retardant technology. It is characterized as a new type of phosphorus-containing flame retardant, delivered in a convenient white powder form. This classification highlights its modern design, moving beyond older technologies to offer enhanced performance in specific polymer applications. The chemical formula of DDP is C17H15O6P, and it is identified by CAS Number 63562-33-4. Its EINECS number is 1592732-453-0. As a fine powder, it is well-suited for incorporation into polymer matrices during processing.

One of the key strengths of DDP is its intended use as a copolymerization combination. This means it can be chemically integrated into the polymer chain, particularly in modified polyester systems. This copolymerization approach offers distinct advantages over simple additive mixing, as it can lead to more stable and long-lasting flame retardancy that is less prone to leaching or migration. When incorporated, the modified polyester exhibits improved hydrolysis resistance, a crucial property for materials exposed to moisture or humid environments. This enhanced durability ensures that the flame retardant properties are maintained over the product's lifespan.

Furthermore, DDP demonstrates excellent flame retardant properties through a mechanism that includes accelerating the droplet phenomenon during combustion. By promoting the formation of molten droplets that carry heat away from the flame front, it reduces the spread of fire. This mechanism, combined with its inherent phosphorus-based flame inhibition effects, contributes to a significantly improved limiting oxygen index (LOI), reported to be in the range of T30-32. A higher LOI indicates that the material requires a greater concentration of oxygen to burn, signifying enhanced flame resistance.

Beyond its technical performance, DDP is noted for having low toxicity and causing only small skin irritation, factors that are increasingly important for material handlers, manufacturers, and end-users, as well as for minimizing environmental impact. These characteristics make it a more favorable choice compared to some traditional halogenated flame retardants that have raised concerns regarding their environmental persistence and potential health effects.

The applications of DDP are diverse and target areas where stringent fire safety standards are critical, particularly when using modified polyester. It is well-suited for interior decoration in various high-risk environments. This includes applications in the automotive sector, where materials must meet strict fire safety regulations for occupant protection. Similarly, in shipbuilding and marine applications, DDP can contribute to creating safer interior spaces. Superior hotel interior decoration is another key application area, where fire safety is paramount for guest safety and regulatory compliance. Its effectiveness in these demanding applications underscores its reliability and performance.

The technical specifications for DDP powder are rigorously controlled to ensure consistent quality. The appearance is consistently a white powder. The assay, measured by HPLC, is specified at ≥99.0%. Phosphorus content (P) is ≥8.92%, confirming its active component. Impurity levels are kept low, with chlorine (Cl) at ≤50ppm and iron (Fe) at ≤20ppm. The melting point range is 188ºC to 194ºC, indicating its thermal stability and suitability for processing within typical polymer manufacturing temperatures.

Packaging for DDP is designed to protect the product's integrity and facilitate handling. It is supplied in 25 kg bags, utilizing a paper-plastic structure lined with aluminum foil packaging. This multi-layer packaging provides protection against moisture and other environmental factors. Proper storage is essential to maintain quality; DDP should be stored in cool, dry places, kept away from fire and moisture sources. These simple storage guidelines help ensure the product remains effective for use.
