Hazardous Combustion Products: Hydrogen chloride, carbon monoxide, carbon dioxide, trace phosgene
Protective Equipment for Firefighters: Full protective suit and self-contained breathing apparatus
Firefighting Instructions: Remove containers from fire area if safe, cool containers with water, prevent water runoff from entering drains
Flash Point: Not flammable as solid, combusts only at high temperatures
Personal Protection: Use respiratory protection, chemical goggles, gloves
Environmental Precautions: Prevent entry into drains, surface waters, or soil
Containment and Cleanup Methods: Sweep or shovel up, avoid dust creation, transfer to labeled waste containers, ventilate area
Decontamination: Wash spill area with water, collect waste water for authorized disposal
Safe Handling: Use local exhaust, minimize dust formation, avoid contact with skin and eyes, keep containers closed when not in use
Storage Conditions: Store in cool, dry, well-ventilated area, maintain away from incompatible chemicals (strong acids, oxidizers, bases), avoid direct sunlight and heat sources
Incompatibilities: Strong acids, alkalis, oxidizing agents
Packaging Materials: Use recommended containers; avoid corrosion-prone packaging
Occupational Exposure Limits: Follow established OSHA, ACGIH, or local workplace exposure limits for vinyl chloride, vinyl acetate, maleic acid
Engineering Controls: Use process enclosures, local ventilation, HEPA filters for dust control
Personal Protective Equipment: Safety glasses or chemical splash goggles, chemical-resistant gloves (nitrile, PVC), workwear, dust mask or respirator (N95 or equivalent) during dusty operations
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke when working with the product
Appearance: White or off-white powder or granules
Odor: Faint, characteristic odor
Melting / Softening Point: 140–180 °C
Boiling Point: Not applicable (decomposes)
Solubility: Insoluble in water; soluble in many organic solvents
Density: 1.3–1.4 g/cm³
Vapor Pressure: Negligible at room temperature
pH (aqueous dispersion): Slightly acidic
Flammability: Not classified as flammable under normal conditions
Explosion Limits: Dust may form explosive mixtures with air in specific concentrations
Chemical Stability: Stable under normal storage and handling conditions
Reactivity: Not reactive under normal use, reacts with strong acids, alkalis, or strong oxidizers
Hazardous Decomposition: Hydrogen chloride, CO, CO₂ on thermal decomposition or combustion
Conditions to Avoid: Heat, open flames, strong sunlight, incompatible materials, high energy sources
Polymerization: Does not undergo hazardous polymerization
Acute Exposure: May cause skin and eye irritation, respiratory tract irritation from dust
Chronic Exposure: Prolonged exposure to vinyl chloride in high concentrations linked to liver toxicity, but resin-bound monomer levels very low
Routes of Exposure: Skin, inhalation, eye contact
Carcinogenicity: Vinyl chloride monomer recognized as carcinogenic, resin matrices limit exposure via dust precautions
Sensitization: No known evidence for sensitization with usual industrial use
LD50/LC50 Data: Not established for full resin mixture, mixture is of low acute toxicity for routine use
Environmental Impact: Not readily biodegradable, may persist in soil and water
Ecotoxicity: Bulk spills may harm aquatic life due to suspended solids
Bioaccumulation: Not expected due to large polymer size
Mobility: Low mobility, will tend to settle in the environment
Other Adverse Effects: Release of dust or decomposition products may affect local air quality
Waste Treatment Methods: Dispose via licensed waste contractor, comply with local hazardous waste regulations
Disposal of Product: Do not discharge to drains or watercourses, incineration or landfill according to regulation
Disposal of Packaging: Empty containers may contain residues, dispose according to all legal requirements
