The selection of flame retardants is a critical decision for product manufacturers, impacting safety, performance, regulatory compliance, and environmental footprint. For decades, halogenated flame retardants have been widely used due to their perceived cost-effectiveness and efficacy. However, a closer examination reveals significant drawbacks that have led to a paradigm shift towards alternatives like Bisphenol A bis(diphenyl phosphate) (BDP).

Traditional halogenated flame retardants, such as brominated compounds, typically function by scavenging free radicals in the gas phase during combustion. While this can be effective, it often comes with undesirable side effects. During burning, halogenated compounds can release toxic and corrosive gases, posing risks to human health and damaging sensitive equipment. Furthermore, many of these compounds are persistent environmental pollutants.

In contrast, BDP, a halogen-free phosphate ester, operates through different mechanisms, primarily char formation in the condensed phase. When exposed to heat, BDP promotes the creation of a stable carbonaceous char layer on the surface of the polymer. This char acts as a physical barrier, insulating the underlying material from heat and oxygen, and preventing the release of flammable volatile gases. This mode of action offers several distinct advantages:

• Reduced Toxicity and Corrosivity: Unlike halogenated flame retardants, BDP does not produce toxic or corrosive combustion byproducts. This makes it a safer choice for both manufacturing environments and end-user applications, particularly in confined spaces like electronic devices or vehicles.
• Environmental Friendliness: As a halogen-free compound, BDP avoids the environmental persistence and bioaccumulation issues associated with some halogenated alternatives. This aligns with the growing global demand for sustainable chemical solutions.
• High Thermal Stability: BDP's superior thermal stability allows it to withstand the high processing temperatures often required for engineering plastics such as PC/ABS and mPPO. Traditional flame retardants can sometimes degrade or volatilize under such conditions, compromising their effectiveness.
• Low Volatility and Hydrolytic Stability: BDP's low volatility minimizes material loss during processing and use, ensuring consistent performance. Its excellent resistance to hydrolysis further guarantees long-term effectiveness, even in humid conditions.
• Synergistic Potential: While BDP is highly effective on its own, it can also synergize with other flame-retardant additives, potentially allowing for lower overall additive loadings while achieving desired performance levels.
