Hazard Statements: May cause skin and eye irritation. Dust can form explosive mixture with air. May cause respiratory irritation.
Precautionary Statements: Wear protective gloves and goggles. Use only in well-ventilated areas. Keep away from heat, sparks, open flames. Avoid breathing dust.
Other Dangers: Static discharge around fine particles. Prolonged inhalation may aggravate pre-existing lung conditions.
Chemical Composition: Polystyrene resin, Brominated flame retardant compound, Blowing agent (e.g. CO2, organic foaming agent), Minor additives (antioxidants, processing aids, pigment)
CAS Numbers: Polystyrene (9003-53-6), Brominated Compound (varies; typically 70156-74-6), Blowing agent (e.g. 75-28-5 isobutane)
Concentration: Polystyrene matrix up to 85%, Flame retardant from 10 to 20%, Blowing agent from 2 to 5%, Additives less than 3%
Impurities: Trace by-products from polymerization, residual monomers below legal limits
Inhalation: Remove victim to fresh air, keep at rest, seek medical attention for symptoms like coughing, shortness of breath
Skin Contact: Wash with soap and water, remove contaminated clothing. Do not apply solvents. Seek medical help for persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing, obtain medical advice.
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention if large amounts are swallowed or symptoms occur.
Suitable Extinguishing Media: Dry chemical powder, foam, CO2, water spray (not a direct jet)
Unsuitable Extinguishing Media: Do not use high pressure water jets as spread may occur
Special Hazards: Releases toxic and irritating fumes like hydrogen bromide, carbon monoxide, carbon dioxide during burning
Protective Equipment: Firefighters should wear full turn-out gear, self-contained breathing apparatus, protective gloves
Instructions: Move undamaged material away from fire zone safely. Cool exposed containers with water-spray. Contain contaminated run-off to avoid sewers.
Personal Precautions: Wear dust mask and gloves, avoid creating airborne dust, keep ignition sources away
Environmental Precautions: Prevent from entering drains, surface water, soil. Notify authorities in case of large spill.
Cleanup Methods: Sweep or vacuum up without raising dust, place in suitable containers for disposal. Use grounded tools. Wash spill area with water after material removal.
Safe Handling: Use explosion-proof equipment where dust is generated, ground all containers, avoid eating or drinking during use. Always use proper PPE.
Storage Conditions: Keep containers tightly closed, store in cool, dry place, away from flames, hot surfaces, oxidizing agents. Avoid exposure to sunlight and moisture.
Incompatible Materials: Strong acids, bases, oxidizers
Exposure Limits: No established limits for masterbatch; consult limits for specific components like brominated compounds, polystyrene dust
Engineering Controls: Local exhaust ventilation, dust extraction at sources, explosion-proof systems in dusty areas
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, flame-retardant clothing where needed, NIOSH-approved dust mask or respirator
Hygiene Measures: Wash hands before break or after use, change contaminated clothing, keep eating areas separate from work area

Odor: Faint aromatic or neutral
Odor Threshold: Not established
pH: Not applicable (solid polymer)
Melting Point: Above 100°C (polystyrene base)
Boiling Point: Not applicable
Flash Point: Above 450°C
Evaporation Rate: Not applicable
Flammability: Combustible at elevated temperatures
Explosive Properties: Dust may form explosible mixtures
Vapor Pressure: Negligible
Vapor Density: Not applicable
Solubility: Insoluble in water
Partition Coefficient: Not determined
Viscosity: Not applicable
Decomposition Temp: Begins decomposing above 250°C
Chemical Stability: Stable under normal temperatures and storage. Avoid strong heat and flames.
Possible Reactions: Polymer decomposition at high temperatures forming smoke, toxic gases such as HBr, CO, CO2
Conditions to Avoid: Exposing to open flame, static discharge, high temperatures
Incompatible Materials: Strong oxidizers, acids, bases
Hazardous Decomposition: Hydrogen bromide, brominated organic fumes, polystyrene monomer fragments
Acute Toxicity: Low toxicity for general use; dust inhalation can irritate respiratory tract; brominated additives exhibit possible organ toxicity on repeated exposure
Skin Corrosion/Irritation: May cause mild irritation or reddening, especially from dust
Eye Irritation: Can cause temporary inflammation, tearing
Inhalation Risks: Repeated or prolonged exposure may aggravate asthma or bronchitis
Sensitization: Not known to sensitize skin, but caution advised for pre-existing eczema
Chronic Effects: Studies on brominated compounds point to thyroid disruption, elevated cancer risk with long-term, high-level exposure
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No direct evidence for finished product; possible for some brominated flame retardants if overexposed
Aquatic Toxicity: Brominated flame retardants toxic to aquatic life with long-lasting impacts
Persistence/Degradability: Polystyrene highly persistent in environment; not readily biodegradable
Bioaccumulative Potential: Flame retardants and polystyrene can accumulate in organisms and up the food chain
Mobility in Soil: Granular solid; risk of surface run-off in pellet form, slow leaching
Other Effects: High risk of microplastic pollution from manufacturing waste; possible food web impacts
Waste Disposal: Avoid dispersing pellets to environment, collect spillage promptly. Dispose of in accordance with local, state, national regulations, preferably by incineration in permitted facility.
Container Handling: Empty containers may retain residues; treat as hazardous. Do not reuse containers for food or drink.
Recycling Possibility: Recycle if possible in appropriate plastic streams; do not landfill where local bans exist.
Special Precautions: Do not incinerate in open air due to toxic fume risk.
UN Number: Not regulated unless containing classified hazardous flame retardant
Transport Hazard Class: Varies by region and brominated compound content
Packing Group: Usually not applicable
Marine Pollutant: Yes, due to brominated compounds
Special Transport Precautions: Avoid generating dust during loading/unloading; use proper labeling
Shipping Label: Provide emergency contact, hazard symbol if classified
Environmental Risk: Prevent spillage to water during transit.
Safety, Health, Environmental Regulations: Subject to REACH, OSHA Hazard Communication Standard, TSCA regulations for listed ingredients
Labeling Requirements: Warning statements for skin/eye irritant, environmental hazard
Restrictions: May face bans or strict reporting under Stockholm Convention for specific brominated flame retardants; RoHS compliance may exclude certain additives
Other Rules: Local authorities may have specific limits for dust emissions, microplastic discharge, or flame retardant thresholds in final product slabs
Worker Protection: PPE regulations apply in manufacturing and handling sites as per regional labor safety law
