As a widely recognized silicone-based flame retardant in the polymer modification industry, DOW FCA-107 has long been valued by formulators for its reliable flame retardant efficiency, good compatibility with engineering plastics, and minimal impact on the mechanical properties of base resins. For years, it has served as a benchmark product in the flame retardant modification of PC and PC alloys, playing an important role in elevating the fire safety performance of electronic and electrical components, automotive interior parts, and household appliance housings.

However, with the global tightening of per- and polyfluoroalkyl substance (PFAS) regulations, traditional FCA-107 and its counterpart products have encountered an increasingly prominent compliance bottleneck. The residual trifluoromethanesulfonic acid (TFMS) and its salts introduced during the synthesis process fall under the restricted PFAS substance scope, making it difficult for modified materials to meet the latest PFAS certification requirements, which has become a major pain point for downstream manufacturers targeting export markets and high-end applications.

Developed as a high-performance silicone flame retardant directly benchmarked against FCA-107, SFR-Si907 is supplied in a free-flowing powder solid form, enabling easy dosing and dispersion in conventional compounding extrusion processes.

SFR-Si907 is recommended for flame retardant modification of polycarbonate (PC) and PC alloys such as PC/ABS, and also demonstrates excellent adaptability across multiple engineering polymer systems including polyamide (PA), polybutylene terephthalate (PBT), and polyphenylene oxide (PPO). This broad applicability allows material formulators to standardize their flame retardant inventory across different resin platforms.

The product delivers significant improvements in both flame retardant stability and flame retardant rating of modified compounds. It promotes the formation of a dense, continuous char layer during combustion, effectively isolating heat and oxygen transfer. In addition to its core flame retardant efficacy, SFR-Si907 also exhibits moderate smoke suppression performance, reducing smoke release density during material combustion and further enhancing the fire safety of end products.

The core technical breakthrough of SFR-Si907 lies in its upgraded synthesis catalyst system. By completely eliminating the use of trifluoromethanesulfonic acid and its salt catalysts in the production process, the product is inherently free of TFMS and its derivatives. This formulation design ensures that SFR-Si907 modified materials can readily pass mainstream PFAS regulatory certifications, fundamentally resolving the restricted substance issue that has troubled traditional FCA-107 equivalent products.
