Composition / Information on Ingredients

Main Ingredient: Acrylic Rubber Polymer
Chemical Identity: Alkyl Acrylate Copolymer
Typical Content: 95–99%
Stabilizers or Additives: Antioxidants (1–3%), fillers (calcium carbonate, processing oil, up to 5%), possible process aids or colorants, trace residual monomers
Impurities: No substances classified as hazardous above declaration limits

First Aid Measures

Inhalation: Move to fresh air, rest and seek medical advice if symptoms develop or persist
Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water, medical attention for persistent irritation
Eye Contact: Flush gently yet thoroughly with plenty of water for at least 15 minutes, remove contact lenses, medical attention for ongoing irritation
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical advice
Most Important Symptoms: Respiratory irritation, red eyes, dry skin, gastrointestinal upset (rare)

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical or CO₂
Fire Hazards: On thermal decomposition, emits hazardous vapors like carbon monoxide, carbon dioxide, nitrogen oxides
Special Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus
Firefighting Procedures: Cool exposed containers with water, avoid inhaling fumes
Explosion Risk: Fine dust particles can form explosive mixtures with air under the right conditions

Accidental Release Measures

Personal Precautions: Ventilate area, use recommended personal protective equipment (gloves, goggles, mask)
Environmental Precautions: Avoid uncontrolled release into drains, watercourses, or soil
Cleanup Methods: Collect mechanically without generating dust, place in suitable labeled containers for disposal, wash spill area with water after removal
Disposal: Dispose of in accordance with national and local regulations

Handling and Storage

Handling: Use only in well-ventilated or exhaust-equipped areas, avoid formation and inhalation of dust, prevent contact with eyes and skin, practice good industrial hygiene
Storage: Store in cool, dry and well-ventilated area, keep away from sources of ignition, oxidizing materials, acids or strong bases, store in closed containers to prevent contamination
Incompatibility: Minimize contact with strong oxidizers and acids
Other Precautions: Keep out of reach of unsupervised personnel or children

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust or general ventilation to control airborne dust or fumes
Respiratory Protection: Approved dust respirator or mask during processing where dust becomes airborne
Eye Protection: Safety eyewear with side shields
Skin Protection: Chemical-resistant gloves, long sleeves, protective shoes
Hygiene Measures: Ensure washing facilities close by, wash hands before eating or breaks, remove contaminated clothing after handling
Exposure Limits: No established occupational exposure limit for finished polymer, but minimize exposure to nuisance dust below 10 mg/m³ for total dust (OSHA PEL)

Physical and Chemical Properties

Appearance: White to light yellow, elastomeric solid or crumb
Odor: Slight or odorless
pH: Not applicable (solid material)
Melting Point/Range: Greater than 100°C (decomposes before melting)
Boiling Point: Not applicable
Flash Point: Above 250°C (closed cup)
Flammability: Combustible at high temperature
Solubility: Insoluble in water, soluble in strong organic solvents like chlorinated aromatics
Vapor Pressure: Not applicable
Density: 1.15–1.30 g/cm³
Other Properties: Softening point depends on grades, remains flexible to low temperatures, moderate resistance to swell by oils and fuels

Stability and Reactivity

Chemical Stability: Stable at ambient conditions and under recommended storage
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, traces of acrylic monomers might release if overheated
Conditions to Avoid: Exposure to high temperatures, open flames, strong acids or alkalis, ultraviolet light
Incompatible Materials: Strong oxidizers, peroxides, halogens

Toxicological Information

Acute Toxicity: Low toxicity for finished product; dust may cause minor irritation to respiratory tract, eyes or skin
Chronic Effects: No evidence of sensitization or carcinogenicity for properly compounded materials in current industrial use
Routes of Entry: Inhalation, dermal, ocular
Irritation: Mechanical irritation from processing dust
Other Information: Finished rubber contains less than 0.1% residual acrylate monomers, minimizes any toxicity concern

Ecological Information

Ecotoxicity: Stable polymer, unlikely to pose short-term hazard to aquatic or terrestrial ecosystems
Persistence and Degradability: Not readily biodegradable, expected to persist in the environment
Bioaccumulation Potential: Not likely to bioaccumulate due to high molecular weight, low water solubility
Mobility in Soil: Immobile, will remain in upper layers of soil or sediment
Other Adverse Effects: No known significant hazard to environmental organisms under normal use and disposal practices

Disposal Considerations

Waste Treatment Methods: Dispose of surplus or non-recyclable material in compliance with local, state and federal regulations, landfilling or incineration in permitted facilities
Packaging Disposal: Clean containers for recycling if possible, otherwise treat as municipal solid waste or incinerate
Do Not: Discharge waste into sewers, surface waters or soil
Other Instructions: Use authorized waste management services, document disposal for audit purposes

Transport Information

UN Number: Not regulated for transport
Proper Shipping Name: Acrylic Rubber Compound
Hazard Class: None
Packing Group: None
Special Precautions: Keep containers securely closed, store upright to prevent spillage, avoid transport with incompatible substances
Transport Labels: Not required

Regulatory Information

TSCA Inventory: Listed
REACH Registration: Monomers registered, polymer exempt from registration
OSHA Status: Not hazardous as per OSHA Hazard Communication Standard
SARA Title III: Not reportable
Other National Regulations: Meets US, European, and selected Asian safe handling requirements
Labeling Recommendations: Physical handling warnings for dust inhalation, keep out of direct sunlight, do not incinerate in closed containers
