Precautionary Statements: Avoid dust formation, handle in well-ventilated areas, keep away from open flames and heat sources

Composition / Information on Ingredients

Main Ingredient: Chlorinated rubber polymer, 100% (for pure material)
Impurities: Residual chlorine (1-2%), traces of organic chlorides
Additives: No additives in pure material; coatings and paints may introduce solvents, pigments or plasticizers
Hazardous Components: None in pure form; refer to specific formula for any mixture

First Aid Measures

Inhalation: Move individual to fresh air, seek medical attention for difficulty breathing or cough
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Eye Contact: Rinse gently under running water for 15 minutes, remove contact lenses if present, seek medical help if irritation persists
Ingestion: Rinse mouth with water, seek professional medical advice, do not induce vomiting unless directed
Most Important Symptoms and Effects: Dust-induced irritation of eyes, skin, and respiratory tract; seek medical help for persistent symptoms

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, water spray, carbon dioxide
Specific Hazards: Decomposition at high temperatures releases toxic chlorine and hydrogen chloride gases
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective clothing
Special Procedures: Keep upwind, avoid inhalation of combustion products, cool exposed containers with water spray
Combustion Products: Hydrochloric acid, chlorine, phosgene and dense smoke possible above 200°C

Accidental Release Measures

Personal Precautions: Wear respiratory protection, chemical-resistant gloves, avoid skin and eye contact
Environmental Precautions: Contain spills to prevent release to water bodies; avoid discharge into drains, sewers or surface water
Cleanup Methods: Sweep or vacuum solid material using explosion-proof equipment, transfer to labeled containers for disposal
Reference to Other Sections: See personal protective equipment and disposal recommendations

Handling and Storage

Safe Handling: Use only with adequate ventilation, avoid generation of airborne dust, keep away from ignition sources, wear protective gear
Storage Conditions: Store in tightly closed containers, dry, cool, well-ventilated area away from oxidizers or strong acids
Incompatibilities: Strong oxidizing agents, alkalis, amines, high heat, direct sunlight
Packing Materials: Use corrosion-resistant, sealed containers

Exposure Controls and Personal Protection

Control Parameters: No occupational exposure limits established for polymer; dust limits may apply (OSHA PEL for nuisance dust: 15 mg/m³ total, 5 mg/m³ respirable fraction)
Engineering Controls: Local exhaust ventilation recommended for dust control, mechanical ventilation may add further safety
Personal Protective Equipment: Safety glasses with side shields, chemical-resistant gloves (nitrile, neoprene), dust mask or NIOSH-approved respirator if dust exceeds limits, disposable coveralls in dusty work
Hygiene Measures: Wash hands and exposed skin after handling; do not eat, drink or smoke in work area
Environmental Controls: Emission controls for dust or solvent vapors in manufacturing and application settings

Physical and Chemical Properties

Appearance: White to off-white powder or granular solid
Odor: Mild, faint chlorine smell at high concentrations
pH: Not applicable (insoluble in water)
Melting/Softening Point: No clear melting point; softens above 110°C
Flash Point: >200°C (for polymer); lower for products containing solvents
Solubility: Insoluble in water; soluble in aromatic hydrocarbons, esters, ketones
Density: 1.55–1.75 g/cm³
Vapor Pressure: Negligible at ambient temperatures
Boiling Point: Not applicable (decomposes before boiling)

Stability and Reactivity

Reactivity: Stable under recommended handling and storage conditions
Chemical Stability: Avoid excessive heat, strong acids and alkalis, oxidizers
Possibility of Hazardous Reactions: Not reactive with most materials; decomposition may occur at high temperatures
Conditions to Avoid: Open flames, hot surfaces, direct sunlight, generation of dust
Incompatible Materials: Strong oxidizers, concentrated acids, alkalis, amines
Hazardous Decomposition Products: Hydrogen chloride, phosgene, chlorine gas, carbon oxides

Toxicological Information

Acute Toxicity: Non-toxic as polymer; dust irritates eyes, skin, respiratory tract
Chronic Effects: Prolonged exposure to high dust levels may worsen asthma or bronchitis
Sensitization: No data available for sensitization; rare reports of contact dermatitis
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Mutagenicity: No evidence of genotoxicity tested in standard assays
Specific Target Organ Toxicity: None expected at typical occupational exposure levels
Other Health Effects: No known systemic toxicity from normal use

Ecological Information

Eco-toxicity: Not acutely toxic to aquatic or terrestrial organisms as a polymer; may persist in environment
Persistence and Degradability: Not readily biodegradable, persists in soil and water
Bio-accumulative Potential: Low, as high molecular weight reduces absorption by living organisms
Mobility in Soil: Practically immobile owing to low water solubility and particle size
Other Adverse Effects: Finer dust risks polluting waterways; best practice limits uncontrolled environmental release

Disposal Considerations

Waste Treatment Methods: Dispose of as non-hazardous industrial solid waste; consult local, regional, or national regulations for proper landfill or incineration
Contaminated Packaging: Containers should be emptied completely before disposal or recycling; rinse with suitable solvent if required
Special Precautions: Do not incinerate in open air or municipal waste streams to avoid toxic gas emissions
Additional Information: Contract with licensed chemical disposal companies if disposal at site is not possible

Transport Information

UN Number: Not regulated for transport as a hazardous material (pure polymer form)
UN Proper Shipping Name: Not classified
Transport Hazard Class: Not assigned for this material
Packing Group: None for pure product
Environmental Hazards: Not marine pollutant
Special Precautions: Protect from moisture, sparks, open flames during transport, secure storage containers to prevent tipping or damage

Regulatory Information

Occupational Safety and Health Laws: Product may be subject to workplace dust exposure limits (see Exposure Controls)
TSCA: Listed in the United States Toxic Substances Control Act Inventory
REACH: Not classified as a substance of very high concern in EU database
RoHS/ELV: Not restricted in electrical or automotive applications
Other Regulations: Polymer is not a hazardous chemical under OSHA Hazard Communication Standard; state regulations may apply for blends containing hazardous solvents
Labeling Recommendations: Maintain up-to-date information on containers, available to workers and emergency responders
