Flame Retardants, Polypropylene (PP)

PPV2-6 V-2 Flame Retardant Masterbatch for Polypropylene (P/Br Synergistic)

PPV2-6 is a high-efficiency phosphorus–bromine synergistic flame retardant masterbatch designed for polypropylene. With ≥80 percent active content, it delivers UL94 V-2 at only 6 percent loading and can achieve UL94 V-0 at 3–10 percent depending on formulation and thickness. PPV2-6 offers excellent heat stability, no precipitation, and clean processing performance. Its imported compatibilizer carrier provides strong bonding and uniform dispersion in PP, ensuring reliable flame retardancy with minimal impact on mechanical properties.

Attributes

Key Features and Benefits
