Suitable Extinguishing Media: Water spray, dry powder, foam, or carbon dioxide
Unsuitable Extinguishing Media: High-pressure water streams may cause dust-laden air
Special Hazards: Thermal decomposition can produce carbon monoxide, carbon dioxide, acetic acid, and hydrocarbons
Protective Equipment: Self-contained breathing apparatus, full protective gear for firefighters
Fire & Explosion Sensitivity: Product is not highly flammable, yet dust layers can pose explosion risk in confined spaces
Personal Precautions: Avoid inhalation of dust; wear personal protective equipment including dust mask, safety goggles, and gloves
Environmental Precautions: Prevent discharge into drains, sewers, or waterways; restrict spread using suitable barriers
Containment Methods: Use industrial vacuum or damp sweeping to minimize dust generation
Cleaning Up: Shovel spilled pellets into suitable containers for recovery or disposal; ventilate area thoroughly
Handling Precautions: Operate with adequate local ventilation to control dust; avoid sources of ignition; maintain housekeeping to avoid dust accumulation
Safe Storage Conditions: Store in a cool, dry, and well-ventilated location away from sunlight and incompatible materials such as oxidizing agents
Storage Containers: Seal original containers tightly; avoid exposure to moisture to prevent clumping
Storage Temperature: Ambient temperatures recommended to avoid product degradation
Occupational Exposure Limits: No established limits for this product; treat nuisance dust according to regulatory limits (typically 10 mg/m³ for total dust, 5 mg/m³ for respirable fraction)
Engineering Controls: Use process enclosures, ventilation systems, and dust collection as needed
Respiratory Protection: Dust mask or respirator if airborne dust is generated
Eye Protection: Safety goggles or face shield where dust or splashes are possible
Skin Protection: Chemical-resistant gloves and work clothing for prolonged handling
Appearance: White to off-white pellets or powder
Odor: Odorless or faint odor of acetic acid if overheated
pH: Not applicable
Melting Point/Range: 160－190°C, depending on grade
Boiling Point: Not applicable
Flash Point: Not readily flammable
Evaporation Rate: Not applicable
Flammability: Dust can form explosive mixtures with air
Vapor Pressure: Not applicable
Decomposition Temperature: Above 230°C; decomposition can emit hazardous gases
Solubility in Water: Insoluble under ambient conditions
Density: Approximately 1.13－1.21 g/cm³ (grade dependent)
Chemical Stability: Stable under normal storage and handling
Conditions to Avoid: Strong sunlight, excessive heat, sparks, open flames, and static accumulation
Incompatible Materials: Strong oxidizing agents; acids and bases may affect polymer stability
Hazardous Decomposition: Decomposition releases carbon monoxide, carbon dioxide, methane, acetic acid, and volatile organic compounds
Polymerization: Not expected to occur under standard conditions
Acute Toxicity: Not acutely toxic by oral, dermal, or inhalation exposure in standard laboratory testing
Skin Corrosion/Irritation: Not a skin irritant; mechanical irritation possible with repeated contact
Serious Eye Damage/Irritation: Mechanical irritation may occur, especially from dust
Respiratory Sensitization: No evidence of respiratory or skin sensitization in animal studies
Chronic Toxicity: No long-term effects observed in studies; considered biologically inert
Carcinogenicity/Mutagenicity: Not classified as carcinogenic, mutagenic, or reprotoxic under current regulations
Other Information: No clear evidence linking product to specific adverse health effects in humans
Ecotoxicity: Not acutely toxic to aquatic or terrestrial organisms based on available data
Persistence and Degradability: Does not degrade rapidly; remains stable over long periods in natural settings
Bioaccumulative Potential: Not expected to bioaccumulate due to large molecular size and insolubility
Mobility in Soil: Tends to remain where released; limited mobility through soil for bulk pellets
Environmental Fate: Typically persists as solid waste; can contribute to microplastic build-up if not properly managed
Waste Disposal Methods: Prefer recycling where available; disposal in accordance with local, regional, and national regulations
Incineration: Possible in facilities equipped to manage polymer decomposition products (acid gases, VOCs)
Landfill: Acceptable for non-contaminated product; ensure compliance with waste management authority
Contaminated Packaging: Clean containers can be recycled with similar plastics; dispose of contaminated packaging in accordance with relevant guidelines
