Flame Retardants

FRP-950-1 Microencapsulated Red Phosphorus Flame Retardant Masterbatch

FRP-950-1 is a high-performance microencapsulated red phosphorus flame retardant masterbatch designed for engineering polymers that require durable, halogen-free fire protection. It contains ≥80 percent red phosphorus and uses a high-compatibility polymer carrier to ensure strong dispersion, low migration, and long-term stability. FRP-950-1 achieves UL94 V-0 at 2.0 mm with only 3–7 percent additive loading while maintaining mechanical strength, surface appearance, and thermal processing performance.

Attributes

Key Features and Benefits

• High red phosphorus content (≥80 percent) delivers strong flame-retardant efficiency.
• Low addition level (3–7 percent) achieves UL94 V-0 at 2.0 mm.
• Microencapsulated construction prevents oxidation and improves storage stability.
• Kindle temperature ≥360 °C supports PA, PBT and PET processing conditions.
• Fine particle size (~2500 mesh) ensures uniform dispersion in polymer melts.
• Excellent compatibility with PA, PET, PBT and selected polyolefins.
• Non-blooming, low-migration performance supports long-term durability.
• Low moisture absorption improves handling and reduces processing defects.
• Halogen-free and compliant with RoHS, REACH and ISO quality standards.
• Clean, dust-free pellets improve safety and compounding hygiene.
