MSDS for PVC Regrind

Identification

Product Name: Polyvinyl Chloride (PVC) Regrind
Product Code: PVC-RG
Manufacturer: Name and address of the regrind producer/distributor
Emergency Contact: Emergency telephone number for incidents
Recommended Use: Manufacturing of plastic products, extrusion, injection molding

Hazard Identification

Classification: Not classified as hazardous under current OSHA hazard communication regulations
Physical Hazards: Fine particulate may cause dust accumulation; heated PVC releases hydrogen chloride and possible harmful fumes
Health Hazards: Inhalation of dust can cause respiratory irritation; eye contact with dust can cause mechanical irritation; long-term exposure to decomposed fumes has been associated with chronic respiratory effects
Environmental Hazards: Fragments may persist in the environment; no significant acute aquatic toxicity
Label Elements: Use of safety glasses and dust masks recommended during handling

Composition / Information on Ingredients

Main Ingredient: Polyvinyl Chloride (CAS Number: 9002-86-2), percentage typically over 90%
Additives: Plasticizers, stabilizers, fillers such as calcium carbonate, pigments, sometimes trace residual monomers
Other Ingredients: May contain residual solvents or lubricants depending on prior processing; substance concentrations are typically non-hazardous when handled properly

First Aid Measures

Inhalation: Move affected person to fresh air; provide oxygen if breathing is difficult; seek medical attention if symptoms persist
Skin Contact: Wash exposed skin with soap and water to remove dust and particulate; seek medical advice if irritation develops
Eye Contact: Flush eyes with large amounts of water for at least fifteen minutes; remove contact lenses; consult physician if discomfort continues
Ingestion: Rinse mouth with water; it is unlikely in industrial settings, but seek medical attention if large quantities are consumed or symptoms occur

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Specific Hazards: PVC is self-extinguishing but can decompose at high temperatures, releasing hydrogen chloride and phosgene gases
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Advice: Cool exposed closed containers with water spray; avoid inhaling gases from combustion

Accidental Release Measures

Personal Precautions: Wear personal protective equipment to prevent dust inhalation and eye contact
Environmental Precautions: Contain spillage to prevent entry into drains or watercourses, collect using mechanical means
Cleanup Methods: Clean up using industrial vacuums or sweeping, avoid creating airborne dust; dispose of in accordance with local regulations

Handling and Storage

Safe Handling: Work in well-ventilated area; use mechanical ventilation if dust risk exists; avoid creating dust clouds; no smoking or open flames
Storage Requirements: Store in cool, dry area, away from strong acids, bases, and oxidizing agents; keep away from direct sunlight and moisture
Incompatible Materials: Store away from heat sources; PVC can degrade over time if exposed to UV light

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established TLV for PVC, though nuisance dust limits apply (e.g., 10 mg/m³ for total dust)
Ventilation: Use local exhaust to control dust exposures
Personal Protective Equipment: Safety goggles, dust mask or respirator (NIOSH-approved if dust levels are high), gloves for general hand protection, coveralls for large-scale handling
Environmental Controls: Implement measures to prevent dust emissions into work area and environment

Physical and Chemical Properties

Appearance: Granular, flaked, or powdered material, color varies depending on prior use and pigmentation
Odor: Odorless or faint plastic smell
Odor Threshold: Not applicable
pH: Not applicable
Melting Point: Softening point around 75-105°C, decomposes above 140°C
Boiling Point: Not applicable
Flash Point: Not flammable in solid state
Flammability: Not easily ignited, but will burn in continuous flame exposure
Explosion Limits: Dust can pose explosion risk in certain concentrations
Vapor Pressure: Not applicable
Density: Approximately 1.3–1.5 g/cm³
Solubility: Insoluble in water, soluble in some organic solvents at high temperatures
Partition Coefficient (n-octanol/water): Not determined
Auto-ignition Temperature: More than 455°C
Decomposition Temperature: Decomposes above 140°C with release of corrosive gases

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Not reactive under normal use
Hazardous Reactions: May react with strong acids, bases, or oxidizers; releases hydrogen chloride gas on heating
Conditions to Avoid: Prolonged exposure to temperatures above 140°C, flames, and direct sunlight
Hazardous Decomposition Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide

Toxicological Information

Acute Toxicity: Low oral and dermal toxicity, primary risk from dust inhalation irritating respiratory tract
Skin Contact: Non-irritating in most conditions, mechanical abrasion possible
Eye Contact: Can cause mechanical irritation and redness
Inhalation: Inhalation of decomposition fumes can be harmful; chronic exposure to dust may aggravate respiratory disorders
Carcinogenicity: Some plasticizers and residual monomers carry potential cancer risk but generally present in regrind at low, non-hazardous concentrations
Other Health Effects: No evidence for sensitization through skin or respiratory contact; minimal risk in proper use scenarios

Ecological Information

Ecotoxicity: Not acutely toxic to aquatic life; microplastic persistence can cause ecological impact over time
Persistence and Degradability: Resistant to degradation; slowly breaks down under ultraviolet exposure
Bioaccumulative Potential: Unlikely to bioaccumulate due to large particle size
Mobility in Soil: Not soluble, tends to remain where deposited; risk of mechanical spread by wind or water flow
Other Adverse Effects: Potential to contribute to long-term microplastic pollution if not managed properly

Disposal Considerations

Waste Disposal Methods: Recycle where possible; landfill or incineration under authorized conditions where recycling unavailable
Special Considerations: Avoid uncontrolled release; do not incinerate in open fires due to risk of harmful gas emissions
Disposal Code: Follow local, regional, and national waste regulations for synthetic polymer waste

Transport Information

UN Number: Not regulated as a hazardous material for transport
Proper Shipping Name: Polyvinyl Chloride Scrap/Regrind
Transport Hazard Class: Non-hazardous; handle as industrial material
Packing Group: Not classified
Transport Precautions: Secure cargo to prevent spillage and dust release

Regulatory Information

OSHA: Material not listed as hazardous; subject to general workplace safety and dust regulations
TSCA: Main component and most additives listed
REACH: Polymers generally exempt, additives must be registered if imported to EU in significant quantities
Other Regulations: Waste handling subject to national environmental protection rules; status may vary according to residual additives and origin
Label Requirements: Comply with national and regional labeling for industrial substances
Community Right-to-Know: Some additives may be reportable under SARA Title III in the United States
Local Compliance: Users must check for relevant state, provincial, or national safety codes impacting handling and disposal
