Composition / Information on Ingredients

C9 Aromatic Hydrocarbon Resin: 100%
Impurities: Trace levels of polycyclic aromatic hydrocarbons; supplier can provide information on specific low-concentration impurities upon request
Additives: Usually contains no other additives; end users should check batch specifications for rare stabilizers or anti-oxidants

First Aid Measures

Inhalation: Remove to fresh air, keep comfortable for breathing, seek medical attention for persistent cough or difficulty breathing
Skin Contact: Remove contaminated clothing, wash skin with soap and water thoroughly, see a healthcare provider if irritation continues
Eye Contact: Rinse under gentle running water for several minutes, remove contact lenses if present, persistent redness or pain demands examination by a physician
Ingestion: Rinse mouth with water, do not induce vomiting, obtain professional medical evaluation if large quantities consumed or symptoms develop

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, CO2, foam, water spray for cooling and containment
Unsuitable Extinguishing Media: High pressure water jets may spread molten resin
Special Hazards: Melts and burns with dense smoke and irritating, potentially toxic fumes (such as carbon oxides, aromatic hydrocarbons)
Protective Equipment: Full firefighting turnout gear, self-contained breathing apparatus required for all responders in confining or smoky space
Firefighting Instructions: Move containers away from fire if safe; cool exposed surfaces with water

Accidental Release Measures

Personal Precautions: Avoid inhalation and skin contact, use protective gloves, eyewear, recommended respiratory protection in case of airborne dust or vapor
Environmental Precautions: Prevent entry to sewers, drains, surface waters; report significant spills per local regulations
Cleanup Methods: Collect solid or cooled material mechanically, minimize dust generation, transfer to proper waste container, ventilate area
Emergency Procedures: Evacuate unnecessary personnel, use non-sparking tools for large-scale cleanup

Handling and Storage

Safe Handling Practices: Wear protective clothing to prevent skin contact, avoid inhaling fumes from hot material, handle only with proper ventilation
Hygiene Measures: Wash hands thoroughly after handling, do not eat, drink, or smoke until hands are clean
Storage Conditions: Store dry and cool, away from direct sunlight or sources of ignition, maintain containers tightly sealed
Incompatibilities: Strong oxidizers, acids, and heat should be kept away from all resin stock

Exposure Controls and Personal Protection

Occupational Exposure Limit: No specific OELs established for C9 resin; use general dust and vapor controls (total dust not exceeding ACGIH TLV for nuisance particulates, typically 10 mg/m³)
Engineering Controls: Local exhaust recommended, general dilution ventilation for workplace comfort and safety
Personal Protective Equipment: Chemical-resistant gloves (nitrile or PVC), safety glasses or goggles, long-sleeved work wear
Respiratory Protection: Use NIOSH-approved dust/fume respirators if ventilation insufficient or during handling of hot resin
Environmental Controls: Prevent emission to the environment using available technologies such as filters and scrubbers

Physical and Chemical Properties

Appearance: Hard, brittle, pale yellow to dark brown solid or granule
Odor: Mild aromatic hydrocarbon smell
Melting Point: 100–150°C, depending on grade
Boiling Range: Decomposes before boiling
Flash Point: Near 230°C (closed cup, typical values)
Vapor Pressure: Negligible at room temperature
Solubility: Insoluble in water; soluble in hydrocarbons like toluene and xylene
Specific Gravity: Around 1.05–1.15
pH: Not applicable (non-aqueous)
Viscosity: Not a liquid at room temperature

Stability and Reactivity

Chemical Stability: Stable in recommended storage conditions; no dangerous polymerization in sealed containers
Reactivity: Reacts with strong oxidizing agents, can generate heat and off-gassing
Conditions to Avoid: High temperature, direct sunlight, uncontrolled moisture
Hazardous Decomposition Products: Oxides of carbon, aromatic hydrocarbons under fire or intense heat
Incompatible Materials: Avoid mixing with peroxides, nitric acid, chlorine, and other aggressive chemicals

Toxicological Information

Likely Routes of Exposure: Skin contact, eye contact, inhalation of fumes or dust
Acute Effects: Minor skin irritation; eyes may show redness, watering, or stinging; high vapor/dust concentrations can irritate airway
Chronic Effects: No established evidence for chronic toxicity from occasional workplace exposure; long-term uncontrolled exposure to fumes could increase risk for respiratory or skin sensitization
Carcinogenicity: No formal listing from IARC, NTP, OSHA; impurities could include trace aromatics with known carcinogenic properties—keep dust and fumes to a minimum
Medical Conditions Aggravated: Existing respiratory illnesses, dermatitis

Ecological Information

Aquatic Toxicity: Low solubility limits immediate aquatic harm, but solid pieces can physically disrupt aquatic environments
Persistence/Degradability: Product persists in soil and water; very slow biodegradation
Bioaccumulation Potential: Not highly bioaccumulative, though components may concentrate in sediment
Mobility in Soil: Slight; resin will remain near surface unless broken down or mechanically dispersed
Other Environmental Hazards: Spilled material may pose threat to aquatic habitats if not controlled

Disposal Considerations

Waste Disposal Methods: Collect all resin scrap, dust, or spill residue, dispose through a licensed commercial waste service
Container Handling: Do not reuse empty containers unless thoroughly cleaned, treat all residues as potential hazardous waste
Incineration: Acceptable in modern incinerators with exhaust gas scrubbing
Local Regulations: Follow national and local disposal laws; some areas require declarations for non-hazardous industrial waste

Transport Information

UN Number: Non-classified
Proper Shipping Name: Not regulated for ground, sea, air transport in most jurisdictions
Transport Hazard Class: Not regulated
Packing Group: Not applicable
Special Precautions: Avoid extreme heat during transportation, do not stack containers beyond manufacturer’s load recommendations

Regulatory Information

Labelling: Product label and safety instructions accompany each shipment
Chemical Inventory Status: Listed on most major chemical inventories (TSCA, EINECS/ELINCS)
Workplace Safety: Compliant with OSHA, EU REACH requirements for basic industrial chemicals
Community Right-to-Know: Not listed as a hazardous chemical under SARA Title III; local reporting may still apply for large storage or use
VOC Content: Low volatile organic compound content; not typically counted towards facility VOC totals
Other Regulations: Supplier documentation should be checked for country and application-specific legal requirements
