Material Safety Data Sheet (MSDS) for Chlorinated Polyvinyl Chloride (CPVC)

Identification

Product Name: Chlorinated Polyvinyl Chloride (CPVC) Chemical Family: Thermoplastic Polymer Synonyms: CPVC resin CAS Number: 68648-82-8 Recommended Use: Pipes and fittings, industrial fluid handling, hot and cold water distribution, fire sprinkler systems Manufacturer Details: Contact information varies; common manufacturers include Lubrizol, Kaneka, and others Emergency Telephone: Refer to local supplier sheet

Hazard Identification

Classification: Not classified as hazardous under GHS criteria, but thermal decomposition generates hazardous gases Physical Hazards: Dust can irritate respiratory tract; melted resin can cause burns Health Hazards: Inhalation of decomposition products can cause headache, nausea, dizziness, or irritation Environmental Hazards: No significant aquatic hazard in solid form; combustion by-products can be toxic Signal Word: None for product, but caution for thermal breakdown Pictogram: Not required under GHS for bulk resin Hazard Statements: Decomposition may yield HCl, CO, CO₂, phosgene Precautionary Statements: Avoid inhaling dust or decomposition fumes; wash after handling

Composition / Information on Ingredients

Principal Component: Chlorinated Polyvinyl Chloride (CPVC) 98%-100% Additives: Stabilizers, lubricants, impact modifiers (less than 2%) Impurities: Residual vinyl chloride (trace, below detection limits), other proprietary non-hazardous ingredients Hazardous Components: No hazardous components above regulatory thresholds in base CPVC

First Aid Measures

Inhalation: Move to fresh air, seek medical attention if symptoms like coughing or shortness of breath persist Skin Contact: For molten material burns, cool area with water, cover with clean dressing; avoid peeling cooled polymer; seek medical attention for burns Eye Contact: Flush with plenty of water, if irritation or pain persists get medical attention Ingestion: Rinse mouth, seek medical attention if large amounts swallowed Special Advice to Physicians: Treat based on symptoms; inhalation of off-gases may require oxygen administration

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, or CO₂ Unsuitable Media: None known for solid resin Hazardous Combustion Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide, chlorine compounds Special Fire-Fighting Procedures: Self-contained breathing apparatus and full protective gear to avoid exposure to toxic fumes Fire/Explosion Hazards: Product can burn after melting; dust may pose combustion risk if finely divided Specific Methods: Dike firefighting water to prevent environmental contamination

Accidental Release Measures

Personal Precautions: Use appropriate respirators in cases of high dust concentrations; avoid skin and eye contact with dust or molten material Environmental Precautions: Prevent material from entering sewers or waterways Methods for Cleanup: Sweep up solid resin to avoid creating dust clouds; use dust collection systems if available; for molten spills, allow to cool and solidify, then mechanically remove Disposal: Place collected material in properly labeled containers for recovery or disposal according to local regulations

Handling and Storage

Safe Handling: Minimize dust generation and accumulation; avoid breathing dust and fumes from heated material; handle with care to avoid contact with hot polymer Protective Measures: Operate with local exhaust ventilation in areas where dust or decomposition fumes may form Storage Conditions: Store in a cool, dry, well-ventilated area away from strong oxidizers or high heat Incompatible Materials: Strong acids, bases, oxidizing agents Storage Stability: Stable at normal temperatures and storage conditions

Exposure Controls and Personal Protection

Exposure Limits: OSHA PEL for nuisance dust: 15 mg/m³ (total), 5 mg/m³ (respirable); ACGIH TLV for inert dust: 10 mg/m³ Engineering Controls: Local exhaust ventilation for dust and fume control Personal Protection: Respiratory Protection: NIOSH-approved dust mask or respirator for dusty environments Eye Protection: Safety glasses with side shields Hand Protection: Heat-resistant gloves for molten polymer Skin Protection: Long-sleeved protective clothing as needed Hygiene Measures: Wash hands before eating, avoid inhaling decomposition fumes

Physical and Chemical Properties

Physical State: Solid, granular or powder form Color: Off-white to light yellow Odor: Slight plastic odor pH: Not applicable Melting Point: Softens at 110°C – 125°C Boiling Point: Not applicable (decomposes) Flash Point: Not easily flammable Decomposition Temperature: Above 200°C Vapor Pressure: Negligible Solubility in Water: Insoluble Density: 1.5 – 1.7 g/cm³ Other Data: May generate static electricity, use appropriate grounding

Stability and Reactivity

Chemical Stability: Stable at normal storage and use temperatures Decomposition: Releases hydrogen chloride, carbon monoxide, and possible traces of phosgene above 200°C Conditions to Avoid: High temperatures, open flame, sparks Incompatible Materials: Strong acids, bases, oxidizing agents Hazardous Polymerization: Does not occur under normal storage Reactivity: Negligible at room temperature

Toxicological Information

Acute Toxicity: Low toxicity by ingestion, inhalation, skin contact; primary risk from decomposition products Skin Corrosion/Irritation: Molten material can cause burns; dust may cause mild irritant Serious Eye Damage/Irritation: Dust can be irritant Respiratory or Skin Sensitization: Not a sensitizer Specific Target Organ Toxicity: None identified for solid resin Carcinogenicity: Not classified as carcinogenic by OSHA, IARC, NTP; vinyl chloride monomer is a known carcinogen but levels in finished resin below detection Reproductive Toxicity: Not identified Chronic Toxicity: Prolonged exposure to thermal breakdown products may cause respiratory issues Potential Health Effects: Main concern is from thermal decomposition gases, not from the solid resin itself

Ecological Information

Ecotoxicity: Not harmful in solid form; does not leach hazardous substances under typical conditions Persistence and Degradability: Not readily biodegradable Bioaccumulation: Not expected to bioaccumulate Mobility in Soil: Immobile as solid particles Other Adverse Effects: Should prevent material from entering aquatic environments or soil during disposal to avoid chronic microplastic pollution

Disposal Considerations

Waste Treatment Methods: Recycling preferred where facilities exist; otherwise, dispose in accordance with local, regional, and national regulations Special Precautions: Incineration of large quantities only in properly equipped facilities to control emissions Packaging Disposal: Clean containers may be recycled or disposed as non-hazardous waste Disposal Restrictions: Do not allow material to reach waterways or open environments

Transport Information

UN Number: Not regulated Transport Hazard Class: Not classified as dangerous goods Packing Group: Not applicable Environmental Hazards: None identified during normal transportation Special Precautions for Users: Prevent dust formation, avoid high temperatures Bulk Transport: Follow general cargo regulations for plastics

Regulatory Information

TSCA Status: Listed OSHA: Not classified as hazardous under OSHA Hazard Communication Standard EU Classification: Not hazardous according to EC directives; Reach compliant SARA Title III: Not listed as hazardous or reportable substance State Regulations: Check local requirements as vinyl chloride monomer residue may be considered reportable in sensitive jurisdictions Other Requirements: Review workplace air quality and exposure controls as required by national labor authorities
