Product Introduction

HDFR-03 is a halogen-free flame retardant specifically developed for materials such as PA6, PA66, PET, and PBT. It appears as a white powder with excellent thermal stability, high flame-retardant efficiency, and low addition levels. The product offers good compatibility and dispersion with base materials, with no exudation, and exhibits outstanding physical and electrical properties. Its flame-retardant mechanism operates through both condensed and gas phases, achieving flame retardancy by expanding and cross-linking upon exposure to fire. This forms a stable foamed carbon layer and an oil film on the material surface, acting as a protective barrier. The carbon layer is uniform and dense, providing excellent thermal and oxygen insulation without dripping. The flame retardancy rating reaches UL94 V-0 (1.6mm).

Technical Parameters

• Effective Substance Content: 99.8%
• Density: 1.36 g/cm³
• Melting Point: ≥300°C
• Decomposition Temperature: >350°C
• Heating Loss: ≤0.3%

Product Advantages

1. Environmentally friendly and halogen-free.
2. Excellent thermal stability and high flame-retardant efficiency.
3. Uniform and dense char formation, no dripping or exudation.
4. Exceptional physical and electrical properties.

Product Application

HDFR-03 is suitable for both glass fiber reinforced and non-reinforced PA6, PA66, PET, and PBT flame-retardant materials. It exhibits excellent thermal stability, high flame-retardant efficiency, uniform and dense char formation, no dripping, and no exudation, showcasing superior physical and electrical properties.

Recommended Addition Levels

• For PA6/PA66/PET/PBT reinforced materials with +30GF, an addition level of 11-12% is recommended.
• For non-reinforced materials, an addition level of 12-13% is recommended.
  It achieves a UL94 V-0 (1.6mm) vertical burning test rating with no dripping.
