First Aid Measures

Inhalation: Move affected person to fresh air; seek medical attention if breathing remains difficult
Skin Contact: Wash gently with soap and water if irritation occurs; consult a doctor for persistent symptoms
Eye Contact: Rinse thoroughly with water, lifting eyelids occasionally; seek medical attention if irritation persists
Ingestion: Rinse mouth if polymer is swallowed; do not induce vomiting; seek medical attention if large amount ingested or if symptoms develop
Notes for Medical Personnel: No specific antidotes; treat based on symptoms; provide support for respiratory or systemic symptoms caused by inhalation of fumes or dust

Fire-Fighting Measures

Suitable Extinguishing Methods: Use water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Techniques: Direct, strong jets of water may spread molten polymer
Fire Hazards: Polymer burns with release of dense smoke that can contain carbon monoxide, carbon dioxide, and small amounts of irritating fumes
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus with full protective gear
Precautions: Cool exposed containers and equipment with water spray to prevent rupture from overheating; evacuate area if large fire develops

Accidental Release Measures

Personal Precautions: Avoid generating dust; use respiratory protection if dust or vapors accumulate
Environmental Precautions: Prevent entry of spilled material into sewers, soil, or waterways
Methods for Cleanup: Collect with non-sparking tools; sweep up and put in suitable closed containers for disposal; vacuum cleaners fitted with HEPA filters work well for dust; wash area with water after collecting large spills
Disposal of Contaminated Material: Dispose of collected material according to local, state, and federal regulations to prevent possible fire hazard or environmental release

Handling and Storage

Handling: Avoid creating dust and static electricity; ground all processing equipment; ensure local exhaust ventilation in areas where dust or thermal decomposition products may accumulate; minimize heating above processing temperatures
Storage: Store in cool, dry, ventilated areas; keep containers tightly closed; keep away from open flames, sparks, and incompatible materials like oxidizers; do not stack bales beyond recommended limits
Special Considerations: Protect from sunlight and moisture; avoid long-term storage at elevated temperatures to reduce risk of degradation; maintain good housekeeping to avoid fire hazards from dust or spilled pellets

Exposure Controls and Personal Protection

Exposure Limits: No established OSHA or ACGIH exposure limits for finished polymer; monitor for residual monomers like butadiene (TLV: 2 ppm, OSHA PEL: 1 ppm) or styrene (TLV: 20 ppm)
Engineering Controls: Provide adequate general and local exhaust throughout processing areas; enclose sources of dust generation
Personal Protective Equipment: Use safety glasses or goggles for eye protection; gloves recommended when handling; wear appropriate respirator if processing generates dust or fumes above permissible limits; use flame-resistant clothing for emergency response
Hygiene Measures: Wash hands and face before eating, drinking, or smoking; remove contaminated clothing promptly and wash before reuse

Physical and Chemical Properties

Appearance: White to off-white, solid bales or pellets
Odor: Very faint rubber odor
pH: Not applicable
Melting/Softening Point: Softens between 70–90°C (158–194°F), depending on grade
Boiling Point: Not applicable
Flash Point: Greater than 200°C (392°F)
Flammability: Polymer can ignite at high temperatures; dust presents explosion hazard in confined spaces
Vapor Pressure: Negligible
Solubility: Insoluble in water, soluble in aromatic and aliphatic hydrocarbons
Vapor Density: Not applicable
Density: 0.93–0.97 g/cm³
Partition Coefficient: Not available

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions
Conditions to Avoid: Avoid open flames, sparks, hot surfaces, exposure to sunlight, and strong oxidizing agents
Incompatible Materials: Strong acids, strong bases, halogens, and organic peroxides
Hazardous Decomposition Products: Burning produces carbon monoxide, carbon dioxide, hydrocarbons, soot, and traces of irritating or toxic gases
Possibility of Hazardous Reactions: Polymer does not undergo hazardous polymerization; mechanical impact or heating can accelerate degradation

Toxicological Information

Routes of Exposure: Inhalation, eye and skin contact with dust or thermal decomposition fumes
Acute Toxicity: Low acute toxicity; mechanical irritation may occur from dust
Chronic Toxicity: No significant chronic hazards for final polymer; exposure risks from trace levels of monomers like butadiene (classified as carcinogenic, IARC Group 1) only if present above regulatory thresholds
Sensitization: Not expected to cause skin or respiratory sensitization
Carcinogenicity: Major components of finished polymer not classified as carcinogenic; residual monomers monitored for regulatory compliance
Reproductive Toxicity: Not documented for finished SSBR
Additional Information: Fume inhalation during processing can cause respiratory discomfort, headaches, or nausea at high concentrations

Ecological Information

Aquatic Toxicity: Insoluble; expected to pose low acute toxicity to aquatic life
Persistence and Degradability: Resistant to biodegradation under natural conditions; slow decomposition in environment
Bioaccumulative Potential: Not expected to bioaccumulate significantly due to large molecular size
Mobility in Soil: Sinks in water; does not migrate significantly in soils
Other Adverse Effects: May contribute to microplastic pollution if not disposed of properly; persistent in solid waste, can fragment over time

Disposal Considerations

Waste Disposal Methods: Dispose of in accordance with federal, state, and local regulations; avoid burning in open areas
Recommended Treatment: Send to approved landfill or incineration facility equipped for plastics and rubber
Container Disposal: Empty containers should be handled as hazardous if contaminated with processing residues; recommended rinsing and disposal under regulatory guidance
Precautions: Do not discharge waste to sewer systems or waterways; recycling may be possible depending on local facilities
