Hazards: Dust may irritate respiratory tract, mild irritation expected on contact with eyes or prolonged skin exposure, not expected to present long-term hazards under typical industrial use. Avoid dust cloud formation.
Main Components: Ammonium Polyphosphate (40-60%), Melamine Polyphosphate (15-30%), Aluminum Diethylphosphinate (10-25%)
Other Ingredients: Fillers (such as talc, up to 10%), minor dispersants and stabilizers (less than 2%)
Impurities: Usually below detectable limits; data available per batch on request.
Common Blend Ratios: Gradients adjusted according to application.
Inhalation: Move to fresh air, seek medical help if discomfort continues, provide oxygen if breathing is difficult
Skin Contact: Wash with soap and water, remove contaminated clothes, consult physician if irritation appears
Eye Contact: Rinse immediately with plenty of clean water, hold eyelids open, continue rinsing for 15 minutes
Ingestion: Seek immediate medical attention; rinse mouth, do not induce vomiting unless directed by medical personnel
Suitable Extinguishing Media: Dry chemical, water spray, foam, carbon dioxide
Unsuitable Media: Direct streams of water may scatter powder
Special Hazards: Combustion releases phosphorus oxides, nitrogen oxides, ammonia, carbon monoxide and dioxide, avoid inhalation
Firefighting Equipment: Standard full protective gear and self-contained breathing apparatus recommended
Personal Precautions: Wear suitable PPE: gloves, goggles, dust mask or respirator
Spill Procedures: Clean up dry spill with vacuum or shovel; avoid raising dust, ventilate area
Environmental Precautions: Prevent runoff to surface waters, sweep into containers for disposal
Handling: Use with local exhaust ventilation, avoid handling open powders, keep away from food and drinks, wash hands thoroughly after handling
Storage: Store in tightly closed containers, keep cool and dry, protect from moisture, separate from strong oxidizers and acids, store away from incompatible substances
Incompatibilities: Strong acids, alkalis, oxidizers; moisture can degrade product performance
Occupational Exposure Limits: No standardized workplace limits for these additives though treat as nuisance dust (<10 mg/m³ total dust)
Engineering Controls: Local exhaust or process enclosure where possible
Personal Protection: Nitrile gloves, dust-proof goggles, NIOSH-approved respirator for dust
Hygiene Measures: Change clothes before leaving work, avoid eating and drinking in work area
Appearance: White to off-white fine powder
Odor: Odorless to faint chemical smell
pH: 5.0 - 8.5 (10% aqueous solution)
Melting Point: Decomposition above 300°C
Solubility: Insoluble in water, dispersible in polymer matrix
Density: 1.5 - 1.9 g/cm³
Flash Point: Not applicable, product will not burn in solid state
Decomposition Temperature: 280°C and above
Volatility: Non-volatile
Chemical Stability: Stable at room temperature and under normal handling; prolonged exposure to humidity can trigger slow hydrolysis
Hazardous Reactions: Violent reaction with strong oxidizers or strong acids
Decomposition Products: Phosphorus oxides, nitrogen oxides, carbon oxides, small amounts of ammonia on burning
Conditions to Avoid: Heat, open flames, moisture, strong oxidizers, acids
Acute Toxicity: Expected to be low by oral and dermal routes based on published data for main ingredients
Skin Corrosion/Irritation: Mild irritation possible on prolonged contact
Eye Damage/Irritation: Mild but reversible irritation
Respiratory Irritation: Dust may cause irritation for sensitive individuals
Carcinogenicity: Not classified as carcinogenic to humans (IARC/OSHA/ACGIH)
Sensitization: Not expected to cause sensitization
Chronic Health Effects: No significant chronic toxicity data for these flame retardants in animal studies
Special Care: Monitor for dust-related symptoms in routine health checks
Ecotoxicity: Data suggest low toxicity to aquatic life at predicted environmental concentrations, avoid contaminating waterways
Persistence and Degradability: Not readily biodegradable, possible slow hydrolysis in moist soils
Bioaccumulative Potential: Not expected to bioaccumulate
Mobility in Soil: Low; product binds to soil particulates
Other Adverse Effects: No known significant effects or critical hazards in standard environments
Waste Procedures: Dispose in accordance with local, regional, national regulations; send to licensed incinerator or landfill
Packaging: Rinse empty packaging, recycle or dispose as appropriate for material type
Special Procedures: Don’t mix with incompatible waste, avoid releases to environment, keep drums closed
