MELAMINE
Chemical Name: Melamine (1,3,5-Triazine-2,4,6-triamine)
CAS No.: 108-78-1
Application: Key component in intumescent flame retardant (IFR) systems for polymers, coatings, and textiles.
Function: Acts as a blowing agent and nitrogen source, promoting char formation and gas release to suppress combustion.
Item | Index |
Purity,% | ≥99.8% |
Moisture,% | ≤0.1 |
PH value | 7.5-9.5 |
Ash content,% | ≤0.03 |
Color,APHA | ≤20 |
Turbidity,Degree | ≤20 |
Property | Value/Description |
Decomposition Temp. | ~350°C (releases NH₃, CO₂, and H₂O gases) |
Nitrogen Content | 66.6% (highly effective for gas-phase flame inhibition) |
Synergistic Use | Combined with acid sources (e.g., ammonium polyphosphate) and char-forming agents (e.g., pentaerythritol). |
Char Expansion | Forms a porous, insulating carbonaceous layer under heat, blocking oxygen and heat transfer. |
Eco-Friendly: Halogen-free, low smoke, and low toxicity.
High Efficiency: Low loading required (typically 10–30% wt. in polymer matrices).
Thermal Stability: Compatible with processing temperatures up to 300°C.
Versatility: Suitable for polypropylene (PP), polyethylene (PE), polyurethane (PU), epoxy resins, and coatings.
Example IFR System:
Melamine: 20–30% (blowing agent)
Ammonium Polyphosphate (APP): 50–60% (acid source)
Pentaerythritol (PER): 10–20% (carbonization agent)
Performance:
UL-94 Rating: V-0 to V-1 (self-extinguishing).
LOI (Limiting Oxygen Index): >28% (significantly reduces flammability).
Polymer Compounding:
Pre-dry melamine (2–4 hours at 80°C) to avoid moisture interference.
Mix with APP and PER in a twin-screw extruder (processing temp. 180–220°C).
Optimize dispersion for uniform char formation.
Coatings:
Blend with epoxy/polyester resins and fillers (e.g., TiO₂).
Apply via spraying or brushing; cure at 150–200°C
Handling: Use PPE (gloves, goggles) to avoid dust inhalation.
Storage: Keep in a dry, cool place (<30°C) away from acids.
Regulatory: Complies with REACH, RoHS, and IEC 60754-1 (low halogen).
Standard: 25 kg woven bags with moisture-resistant lining.
Custom: Available in bulk or tailored packaging.
