Flame Retardants, Red Phosphorus

FRP-8050 Microencapsulated Red Phosphorus Flame Retardant Masterbatch

FRP-8050 is a microencapsulated red phosphorus flame retardant masterbatch designed for engineering polymers that require high flame-retardant efficiency, strong electrical insulation and halogen-free performance. It uses advanced microencapsulation and an imported compatibilizer carrier to deliver excellent dispersion, thermal stability and long-term mechanical integrity. At low addition levels of 8–10 percent, FRP-8050 achieves UL94 V-0 at 2.0 mm while maintaining smooth surface quality and a high CTI of 600 V. It is ideal for halogen-free wire and cable compounds, electrical components, automotive parts and industrial engineering plastics.
