Product Overview

Eco-Friendly Phosphorus-Based FR Coating Additive

Violet Phosphorus intumescent flame retardant

The FlamEL® RFL series is a phosphorus-based intumescent flame retardant - a liquid additive based on violet phosphorus.

Proprietary encapsulation solves the hydrolysis problem of conventional intumescent flame retardants and delivers excellent thermal stability, widening the processing window. Its high phosphorus content gives outstanding FR performance even at low dosage.

FlamEL® RFL is a phosphorus intumescent FR additive for paint, polyurethane, synthetic leather, and fiber. A high loading of violet phosphorus is held by proprietary encapsulation for hydrolysis resistance, thermal stability, and low volatility.

Recommended Processing

  • Add to paint and coatings to impart flame retardancy

Available Forms

  • Liquid (odorless, transparent)

FlamEL® RFL Series Features

  • High phosphorus content
  • Excellent hydrolysis resistance: proprietary encapsulation vs. conventional intumescent FRs solves the persistent hydrolysis problem
  • Thermal stability and low volatility: overcomes the low processing-temperature limit of conventional intumescent FRs and extends the processing window
  • Non-toxic and environmentally responsible
  • High performance at a low dose (strong cost efficiency)

Key Applications

  • FR additive for paint
  • FR additive for PUD coatings and PU foam (Hard, Soft)
  • FR coatings for leather, fiber, and wood

Technical Features

Mechanism

Proprietary encapsulation against oxygen radicals prevents hydrolysis, and polymerization is induced through oligomeric ethyl ethylene
