Other Additives: Lubricants, pigments, fillers as specified by the technical data sheet; consult manufacturer for full disclosure; hazardous impurities not expected above typical regulatory thresholds
Inhalation: Remove individual to fresh air, seek medical help for persistent discomfort, provide oxygen if breathing becomes difficult
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, seek medical attention for persistent irritation
Skin Contact: Remove contaminated clothing, wash affected areas with soap and water, medical attention not usually necessary unless irritation occurs
Ingestion: Not expected in industrial use, rinse mouth with water, seek medical advice for large accidental intake
Special Notes: Heated resin can cause thermal burns; treat burns as for other thermal injuries
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam
Unsuitable Extinguishing Media: Avoid direct stream of water on molten material, can spread fire
Special Hazards: Burning produces toxic gases such as hydrogen chloride, carbon monoxide, carbon dioxide, phosgene in trace amounts
Fire-Fighting Instructions: Use self-contained breathing apparatus and full protective gear, remove containers from fire area if safe; cool surrounding containers with water
Explosion Hazard: Dust may form explosive mixtures in air; take care in ventilated areas where resin powder is handled; install explosion relief panels in dust-prone zones
Personal Precautions: Evacuate area of unnecessary personnel, equip with dust mask and protective gloves, avoid creating airborne dust
Environmental Precautions: Prevent from entering drains, sewers, waterways; alert authorities if large spill reaches environment
Cleanup Methods: Collect mechanically, use industrial vacuum with HEPA filter for powder, avoid dry sweeping, transfer to appropriate waste containers
Decontamination: Wash affected area with water after large clean-up, ventilate area, ensure equipment is grounded to prevent static discharge
Handling: Employ adequate ventilation, control dust at source, avoid breathing dust or fumes produced by heating, use antistatic devices in transfer systems; don’t eat, drink, or smoke while handling
Storage: Keep resin in cool, dry, well-ventilated area, protected from direct sunlight, heat, and moisture, away from incompatible materials such as strong oxidizers and strong acids
Packing Materials: Store in original tightly sealed containers or approved bulk bins, ensure bags and bins are properly labelled
Special Considerations: Avoid sharp impacts to resin containers, keep pallets stacked properly to prevent collapse or physical hazards
Exposure Limits: No specific OSHA, ACGIH, or EU limits for copolymer; monitor for residual monomers (vinyl chloride TLV 1 ppm in USA, vinyl acetate 10 ppm TWA)
Engineering Controls: Local exhaust ventilation at sources of dust/fume generation; enclosures and explosion-proof equipment in powder-handling areas
Personal Protection: Use dust-resistant safety goggles, impervious gloves (nitrile, PVC), approved half-mask respirator for nuisance dusts, coverall clothing; provide eye-washing station
Hygiene Measures: Industrial hygiene programs, hand-washing facilities, separation of work and break areas
Form: Solid powder or granules
Color: White to off-white
Odor: Faint or slight plastic odor
Odor Threshold: Not established
pH: Not applicable (insoluble in water)
Melting Point/Range: Softening point typically between 80–120°C
Boiling Point: Not applicable
Decomposition Temperature: Begins decomposing above 150–200°C; significant fume generation above 200°C
Flash Point: Not applicable (solid), combustible as dust
Flammability: Not readily flammable, but dust may cause explosions in confined space
Autoignition Temperature: 400–500°C (dust)
Vapor Pressure: Not applicable

Solubility in Water: Insoluble
Partition Coefficient (n-octanol/water): Not determined
Viscosity: Not applicable (solid)
Stability: Stable under normal conditions, avoid temperatures above 150°C
Hazardous Reactions: Exposure to strong oxidizers can cause violent reactions, prolonged heating produces hydrogen chloride gas
Incompatible Materials: Strong acids, bases, alkalis, oxidizing agents, peroxides
Decomposition Products: Hydrogen chloride, carbon monoxide, carbon dioxide, minor amounts of phosgene during combustion or thermal degradation
Polymerization: Will not occur under normal conditions
Other Reactivity: Produces static electricity; take grounding precautions during transfer
Routes of Exposure: Inhalation (primarily dust), skin and eye contact
Acute Effects: Dust may cause minor irritation of eyes, nose, throat; exposure to fumes during thermal decomposition can cause respiratory distress, coughing, dizziness
Chronic Effects: Prolonged or repeated inhalation of high concentrations of dust over months or years may impair lung function, risk increases with improper industrial hygiene
Skin Effects: Prolonged skin contact with dust can cause mild dryness or irritation
Carcinogenicity: The copolymer itself is not classified as carcinogenic; vinyl chloride monomer (VCM) is a known human carcinogen, but only trace residual present in finished resin
Other Health Hazards: No reports of allergic reactions to HA copolymer; heated fumes more hazardous than raw polymer
LD50/LC50: Not applicable; mixture not acutely toxic under normal conditions of use
Aquatic Toxicity: Solid copolymer is not readily bioavailable, low acute aquatic toxicity, but pellets or powder may cause physical effects on aquatic life by ingestion or entanglement
Persistence and Degradability: Not readily biodegradable, persistent in soil and water, slow degradation over many years
Bioaccumulative Potential: Not expected to bioaccumulate due to high molecular weight and low solubility
Mobility in Soil: Low mobility, product is dense and insoluble
Other Ecological Effects: Debris may contribute to microplastic pollution if released in large quantities, monitor waste management
Other Notes: Substance is not classified as hazardous to the environment under most applicable regulations
Waste Treatment Methods: Recover or recycle where possible, dispose in accordance with local, state, and national regulations
Disposal Instructions: Do not discharge to surface waters or drains, transport to permitted industrial landfill, incinerate only in authorized facilities, avoid generating airborne dust during disposal
