Product Name: Polypropylene Carbonate
CAS Number: 25511-85-7
Synonyms: PPC, Poly(propylene carbonate), Poly(propene carbonate)
Recommended Use: Biodegradable polymer, packaging material, specialty plastic applications
Manufacturer: [Insert detailed manufacturer contact information]
Emergency Contact: [Insert 24-hour emergency line]
GHS Classification: Not classified as hazardous by GHS criteria
Health Hazards: May irritate eyes, skin, and respiratory tract through direct contact or dust exposure; ingestion brings low acute toxicity, but stomach upset can occur
Physical Hazards: Dust generated during handling may pose explosion risk in poorly ventilated or static-prone environments
Environmental Hazards: Not expected to cause long-term adverse effects, though excessive release could impact aquatic organisms due to suspended solids
Chemical Identity: Polypropylene Carbonate
Percentage: >99% polymer content
Impurities & Additives: Possible trace residual monomers, solvents under 1%, processing aids as specified on technical datasheet
Molecular Formula: (C4H6O3)n
Inhalation: Move exposed person to fresh air if inhaled dust causes coughing or breathing trouble, seek medical attention in case of persistent symptoms
Skin Contact: Wash off with soap and plenty of water, remove contaminated clothing if irritation develops, consult medical staff for persistent discomfort
Eye Contact: Rinse thoroughly under running water for several minutes, keep eyelids apart, seek professional help if stinging or redness continues
Ingestion: Rinse mouth, drink water to dilute material, and if symptoms develop (nausea, vomiting), contact a healthcare provider
Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide all suitable for suppressing fire
Hazards from Combustion: Thermal decomposition creates carbon monoxide, carbon dioxide, and possibly trace formaldehyde
Protective Equipment: Wear full bunker gear and self-contained breathing apparatus; keep bystanders away
Precautions: Cool fire-exposed containers with water spray to prevent rupture; monitor for airborne fumes
Personal Precautions: Wear dust mask, safety goggles, suitable gloves; prevent skin and eye contact
Environmental Precautions: Stop material from reaching sewers, surface water, or drains
Methods for Clean-Up: Sweep up material without creating dust, use industrial vacuum if possible, store in properly labeled drums for disposal
Handling: Use local exhaust ventilation to limit airborne dust; earth large equipment to prevent static discharge; avoid excessive heat and ignition sources
Storage: Store in cool, dry place, away from direct sunlight and incompatible chemicals; keep container tightly closed
Incompatibilities: Strong acids, strong bases, oxidizing agents can attack polymer matrix
Special Considerations: Use only non-sparking tools, keep out of reach of children and untrained personnel
Occupational Exposure Limits: No specific OSHA or ACGIH limits, but recommended to control nuisance dust to below 10 mg/m³ (total dust), 5 mg/m³ (respirable fraction)
Engineering Controls: Ventilation hoods, dust collectors; periodic air quality monitoring in work zones
Personal Protective Equipment: Dust mask/respirator, chemical-resistant gloves, safety goggles, lab coat or long sleeves
Hygiene Measures: Wash hands before eating, drinking, or smoking at work; frequent laundering of work clothing
Physical State: Solid, granular or powder
Color: White to off-white
Odor: Faint characteristic odor, typically mild
Melting Point: 70–110°C, depends on molecular weight and copolymerization
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at standard temperature
Water Solubility: Insoluble or low solubility
Density: 1.2–1.3 g/cm³
pH: Not applicable (insoluble polymer)
Flash Point: >250°C
Autoignition Temperature: 380°C (approximate)
Chemical Stability: Stable at standard temperature and pressures, sensitive to temperatures above 220°C
Conditions to Avoid: Excess heat, exposure to open flame, strong UV light
Incompatible Materials: Strong acids, bases, oxidizers; will degrade polymer chain
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, traces of acrylaldehyde or organic acids under extreme thermal breakdown
Acute Toxicity: Not acutely toxic by oral, dermal, or inhalation routes in animal tests
Irritation: Dust may cause mechanical irritation to eyes and mucous membranes
Sensitization: No evidence of skin sensitization in available data
Long-Term Effects: No data suggesting carcinogenic, mutagenic, or reproductive toxicity
Other Information: Low bioaccumulation potential; ingestion of large quantities can block digestive tract, particularly for children and pets
Ecotoxicity: Not considered dangerous for aquatic life at realistic concentrations; dust could cause mechanical turbidity
Persistence and Degradability: Biodegrades under industrial composting settings, much slower in soil and water
Bioaccumulation: Unlikely due to polymer insolubility and large molecular size
Mobility in Soil: Low due to insolubility; particles may persist in upper soil layers before degradation
Other Adverse Effects: No evidence of chronic toxicity to fish, birds, or microorganisms in environmental studies so far
Waste Disposal Methods: Send for energy recovery or polymer recycling if available, otherwise landfill per local regulations
Container Disposal: Rinse thoroughly, then recycle or dispose as plastic waste
Special Precautions: Do not burn in open fires due to risk of toxic gases; avoid sewer discharge of fine powders
UN Number: Not regulated for transport
Transport Hazard Class: Not classified as dangerous under DOT, IMO, IATA systems
Packing Group: Not assigned
Environmental Hazards: None specified; keep dry and protect from direct sunlight during transit
Special Transport Precautions: Secure cargo to prevent spills and dust generation
OSHA: Not classified as hazardous under the Hazard Communication Standard
TSCA: Listed on the U.S. Toxic Substances Control Act inventory
EINECS/ELINCS: Listed in the European inventory
SARA Title III: Not subject to reporting under Sections 302, 304, 313
REACH: Registered as polymer, compliance responsibility lies with manufacturer or importer
Canadian WHMIS: Not a controlled product
Other Regulations: Subject to local waste handling requirements and general workplace health and safety laws
