Hazard Class: Not classified as hazardous under GHS for bulk form
Physical Hazards: Dust from processing can accumulate and pose a risk of combustible dust explosion
Acute Health Hazards: Inhalation of dust may cause irritation to respiratory tract, eyes, and skin; ingestion is unlikely but can cause gastrointestinal discomfort
Chronic Health Hazards: Prolonged exposure to high concentrations of dust can impact respiratory health
Ecological Hazards: Not readily biodegradable; may persist in environment
Substance: Synthetic copolymer
Main Components: Styrene (approx. 23.5%), Butadiene (approx. 76.5%)
Impurities: Trace amounts of process oils, emulsifiers, stabilizers, fillers, and other additives
CAS Number (Styrene): 100-42-5
CAS Number (Butadiene): 106-99-0
Additives: Antioxidants, processing aids used in manufacturing
Inhalation: Move person to fresh air, seek medical advice if symptoms continue or breathing feels difficult
Skin Contact: Wash thoroughly with mild soap and water, remove contaminated clothing, seek medical help if irritation develops
Eye Contact: Rinse carefully with clean water for at least 15 minutes, do not rub eyes, get medical attention if redness, pain, or vision changes happen
Ingestion: Do not induce vomiting, rinse mouth, consult a healthcare professional if discomfort or adverse reaction occurs
General Advice: Always consult a medical professional for significant or long-term exposures
Suitable Extinguishing Media: Use foam, dry chemical powder, carbon dioxide, or water fog for larger fires
Unsuitable Extinguishing Media: Avoid direct water jets which can spread burning material
Special Hazards: Hazardous combustion can release carbon monoxide, carbon dioxide, and traces of hydrocarbons
Protective Equipment for Firefighters: Use self-contained breathing apparatus and protective clothing to prevent inhalation of toxic gases
Fire-Fighting Procedures: Contain run-off, cool exposed containers with water spray to prevent rupture
Personal Precautions: Use protective equipment, ensure adequate ventilation, avoid inhaling dust or fumes
Environmental Precautions: Stop the spread, prevent rubber fragments from entering drains, surface water, or soil
Methods for Containment: Gather spilled material using mechanical tools, avoid creating dust
Cleanup Procedures: Collect into labeled containers for recycling or disposal, wash residue from surfaces with water after removal
Emergency Procedures: Notify appropriate authorities as indicated by local regulations
Precautions for Safe Handling: Handle away from sparks, flames, and strong oxidizers; minimize generation of dust or particles; practice good hygiene
Safe Storage Conditions: Store in cool, dry, well-ventilated areas, keep away from heat, sunlight, and incompatible substances
Container Requirements: Store in labeled, tightly closed packaging to avoid contamination
Incompatibilities: Avoid contact with strong acids, bases, and oxidizing agents
Occupational Exposure Limits: No established limits for finished SBR; keep workplace dust below regulatory limits
Engineering Controls: Use local exhaust or general ventilation during processing or cutting
Personal Protective Equipment (PPE): Wear gloves to prevent skin contact, goggles or safety glasses for eye protection, and a dust mask or respirator when airborne dust can form
Hygiene Measures: Wash hands after use, do not eat, drink, or smoke in handling areas, remove contaminated clothing and launder before reuse
Appearance: Solid, rubbery, light to dark beige or black, supplied in bales, pellets, or sheets
Odor: Slight, sweet, characteristic of synthetic rubber
pH: Not applicable (insoluble in water)
Melting Point/Softening Point: 50-90°C (softening range)
Boiling Point: Not applicable for polymer
Flash Point: >260°C
Auto-Ignition Temperature: >400°C
Explosive Properties: Dust may cause explosion in confined spaces
Solubility: Insoluble in water, soluble in aromatic and aliphatic hydrocarbons
Vapor Pressure: Not applicable
Density: 0.92–0.98 g/cm³
Viscosity: Not measured, solid polymer
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Low under normal use, may react violently with strong oxidizers
Hazardous Reactions: No dangerous reaction expected with proper use
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, small quantities of hydrocarbons may form during combustion or thermal decomposition
Conditions to Avoid: Direct heat, flames, sunlight, strong oxidizing agents
Acute Toxicity: Not classified as acutely toxic under GHS, low hazard if handled properly
Skin Contact: Not expected to be harmful; prolonged contact can cause mild irritation
Eye Contact: Dust or particles can irritate, cause redness or discomfort
Inhalation: High levels of airborne dust may cause transient respiratory discomfort
Ingestion: Ingestion highly unlikely, choking hazard if swallowed
Chronic Effects: No chronic effects reported for finished product; monomer residues are strictly regulated
Carcinogenicity: Finished SBR is non-carcinogenic; monomers classified by IARC (Styrene: group 2B, Butadiene: group 1), not present in finished rubber at hazardous levels
Persistence and Degradability: Not easily biodegradable, may persist in soil and water for extended periods
Bioaccumulative Potential: No evidence of bioaccumulation
Mobility: Immobile in environment, floats on water
Aquatic Toxicity: Low toxicity to aquatic organisms, physical obstruction may occur if fragments reach waterways
Other Adverse Effects: Large accumulation can contribute to microplastic pollution if not properly managed
Waste Treatment Methods: Prefer recycling for industrial scrap and unused product
Methods of Disposal: Licensed incineration or landfill in accordance with local, regional, and national regulations
Precautions: Do not discharge into sewers, waterways, or uncontrolled sites
Packing Waste: Dispose of empty packaging in compliance with official requirements
UN Number: Not regulated as a dangerous good under UN transport rules
DOT (US): Not regulated
IMO/IMDG: Not regulated, solid non-hazardous cargo
IATA: Not classified as a dangerous good
Special Precautions for User: Secure bales and pallets to prevent movement during transport, prevent tearing or leakage of packaging
OSHA: Not classified as hazardous under US OSHA Hazard Communication Standard
