Hazard Statements: Dust may cause respiratory irritation. Off-white pellet form reduces immediate risk of airborne release compared to powder.
Precautionary Statements: Avoid breathing dust. Wear protective gear during bulk handling or mechanical processing. Store in a cool, dry, well-ventilated area.
Chemical Name: Melamine cyanurate
CAS Number: 37640-57-6
Content: 98–100% by weight
Additives: Minor pelletizing agents, if any (less than 2% by weight, proprietary, not classified as hazardous)
Molecular Formula: C3H6N6•C3H3N3O3
Inhalation: Remove to fresh air if dust is inhaled. Seek medical attention for any breathing difficulties.
Skin Contact: Wash area thoroughly with plentiful water and mild soap. Remove contaminated clothing.
Eye Contact: Rinse eyes gently with water for several minutes, lifting eyelids. Consult medical help if irritation persists.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Drink water to dilute, seek medical advice if larger quantities consumed or stomach discomfort noticed.
Other: Show MSDS and product label if medical attention required.
Suitable Extinguishing Media: Use water spray, foam, dry chemical or carbon dioxide.
Unsuitable Extinguishing Media: Do not use high-pressure water stream which may spread spilled material.
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, and traces of cyanuric acid may release above 300°C.
Protective Equipment for Firefighters: Use full protective gear including self-contained breathing apparatus.
Other Fire Info: Product by itself is not readily combustible; may aid combustion if involved in a fire with strong heat sources.
Personal Precautions: Avoid breathing dust and contact with eyes or skin. Use gloves and dust mask for large spills.
Environmental Precautions: Keep pellets out of drains, soil, and surface waters.
Spill Clean-up: Scoop or vacuum pellets into suitable containers for reuse or disposal. Wash down spill area with water if significant dust produced.
Disposal for Cleanup: Place collected material in appropriate tightly sealed containers, reuse if not contaminated, dispose following Disposal Considerations.
Precaution for Safe Handling: Handle with good industrial hygiene practices. Use local exhaust ventilation if processing produces dust.
Storage Conditions: Store in tightly closed containers away from moisture and incompatible substances like strong oxidizers and acids.
Other Storage Tips: Stack bags or drums properly to avoid instability. Ensure storage area remains cool and dry to minimize caking and potential clumping.
Occupational Exposure Limits: No established regulatory limits, treat as nuisance dust (e.g., OSHA PEL: 15 mg/m³ total dust, 5 mg/m³ respirable dust).
Engineering Controls: Provide adequate ventilation, especially during pellet transfer, grinding, or blending.
Eye Protection: Use chemical safety goggles if dust formation is likely.
Hand Protection: Wear chemical-resistant gloves (nitrile, PVC, latex).
Respiratory Protection: Use particulate filter mask (N95 or higher) if dust exceeds nuisance thresholds.
Other Protective Measures: Wear long sleeves and closed-toe shoes to reduce skin exposure.
Appearance: Off-white, opaque pellets
Odor: Odorless
pH: 5.0–7.0 (saturated solution)
Melting Point: >300°C (decompose before melting)
Boiling Point: Not applicable
Flash Point: Not flammable under test conditions
Solubility: Slightly soluble in water, insoluble in most organic solvents
Relative Density: About 1.5–1.8 g/cm³
Vapor Pressure: Negligible at room temperature
Other Properties: No explosive or oxidizing properties detected
Chemical Stability: Stable at ambient temperature and pressure under recommended storage.
Decomposition: Prolonged heating above 300°C produces ammonia, carbon oxides, and nitrogen oxides.
Reactivity: Non-reactive under normal use and storage.
Incompatible Materials: Avoid strong oxidizers, acids or alkalis for prolonged periods; decomposition may occur.
Hazardous Polymerization: Will not occur under ordinary conditions of use.
Acute Toxicity: Low oral and dermal toxicity (LD50 oral (rat) >5000 mg/kg, not expected to cause acute systemic effects).
Skin Corrosion/Irritation: Non-irritating under standard handling.
Eye Irritation: Dust may cause mild mechanical irritation.
Respiratory Sensitization: Dust may cause temporary irritation to upper respiratory tract.
Chronic Effects: Repeated exposure to dust may aggravate respiratory conditions.
Carcinogenicity: Not classified as carcinogenic by ACGIH, IARC, NTP, OSHA.
Mutagenicity: No mutagenic effects found in available studies.
Reproductive Toxicity: Not identified in laboratory reports.
Ecotoxicity: Not expected to present significant hazard to aquatic or terrestrial organisms at normal release levels.
Persistence and Degradability: Not readily biodegradable, but expected to slowly degrade abiotically in environment.
Bioaccumulation: No evidence for bioaccumulation; log Kow estimated <1.
Mobility in Soil: Low solubility results in low mobility.
Other Adverse Effects: Avoid uncontrolled release as bulk material may persist and interfere mechanically with soil or water systems.
Waste Disposal Methods: Collect and reuse or send to authorized landfill or incinerator that complies with local, regional, or national laws.
Container Disposal: Rinse, crush, and recycle or dispose of containers in accordance with environmental regulations.
Do Not: Dump large quantities in drains, sewers, or surface waters.
Other: Consult local authorities or a certified waste disposal contractor for guidance regarding specific disposal needs.
UN Number: Not classified as dangerous for transport.
Transport Hazard Class: Not regulated.
Packing Group: Not applicable.
