HOFNIL- Red Phosphorus Master Batch
HOFNIL- Red Phosphorous concentrate is a halogen free flame retardant additive based on red-phosphorus particularly suitable for polyamide articles. It is a free-flowing and dust-free masterbatch in pellets physical form which makes it very easy to handle, accurately to dose and safely to process allowing high consistency in the quality of the final article.
HOFNIL- ZB (Zinc Borate)
(Melamine coated Ammonium Polyphosphate II)
HOFNIL-ZB (Zinc Borate) is a boron-based versatile flame retardant widely used in polymers, plastics, and rubber compounds due to its ability to release water at high temperatures, aiding in fire suppression. It is effective in enhancing the fire resistance of materials such as PVC, polyolefins, elastomers, polyamides, and epoxy resins.
HOFNIL-FR 255
(Melamine Cyanurate-Based Flame Retardant for Polyamides)
HOFNIL-FR 255 is a high-purity melamine cyanurate (MCA) flame retardant additive designed for polyamide (PA6 and PA66) systems. It functions via a synergistic nitrogen-based mechanism, releasing non-flammable gases and promoting char formation during combustion.
Compared to halogenated systems, MCA offers superior thermal stability, low toxicity, and excellent electrical insulation properties, making it a preferred choice for engineering plastics used in safety-critical applications. HOFNIL-FR 255 provides reliable UL94 V-0(for unfilled) & UL94 V-2(glass filled) performance in thin-wall nylon components while maintaining mechanical integrity.

HOFNIL- FR 264
HOFNIL-FR 264 is a blend of halogen-free intumescent flame retardant specifically designed for use in polyolefins, particularly polypropylene (PP) and its copolymers. This white, odorless, and tasteless powder is known for its high efficiency and environmental safety. It is often utilized in conjunction with other flame retardants such as Melamine Cyanurate (MCA) or Melamine Polyphosphate (MPP) to enhance its flame-retardant properties. The intumescent mechanism of HOFNIL-FR 264 allows it to form a protective char layer when exposed to heat, thereby preventing the spread of flames and reducing the release of toxic gases. Its nitrogen and phosphorus composition contributes significantly to its effectiveness, making it a preferred choice for applications requiring stringent fire safety standards.
HOFNIL- FR A2
(Ammonium Polyphosphate II)
HOFNIL-FR A2(Ammonium polyphosphate II) is a widely used flame retardant known for its effectiveness and versatility across a range of applications. It is particularly valued in industries such as paints, coatings, textile and polymer manufacturing due to its ability to enhance fire resistance in materials. FR A2 is a polymeric compound composed of ammonia and polyphosphoric acid.
HOFNIL- FR A2M
(Melamine coated Ammonium Polyphosphate II)
HOFNIL-FR A2M is a widely used flame retardant known for its effectiveness and versatility across a range of applications. Melamine Coated Ammonium Polyphosphate combines ammonium polyphosphate with a melamine coating. This coating enhances the thermal stability, water resistance, and overall performance of the flame retardant in various applications. It features extremely low water solubility, is completely insoluble in organic solvents, non-hygroscopic, non-flammable, and has improved powder flowability.
