First Aid Measures

Inhalation: Move exposed individual to fresh air; medical attention needed if symptoms persist
Skin Contact: Wash area with soap and water; remove contaminated clothing
Eye Contact: Rinse gently with water for at least 15 minutes; seek medical attention if irritation continues
Ingestion: Rinse mouth, do not induce vomiting, consult a physician for further observation
Special Advice: Melted resin can cause burns; cool affected area quickly with plenty of water, avoid pulling solidified material from skin
Notes for Physicians: Symptomatic and supportive treatment only—product shows little evidence for systemic toxicity

Fire-Fighting Measures

Suitable Extinguishers: Use water spray, carbon dioxide, dry chemical powder, or foam
Specific Hazards: Resin dust can create fire hazard, melt flows rapidly and feeds fire
Decomposition: Burning produces CO, CO₂, unidentified organic fumes
Protective Equipment: Full protective gear including self-contained breathing apparatus required for large fires
Thermal Hazards: Missing ventilation lets vapors accumulate, which can ignite above flashpoint
Advice for Firefighters: Cool containers exposed to flames with water spray; avoid entering confined spaces with smoke buildup

Accidental Release Measures

Personal Precautions: Avoid dust inhalation, wear safety goggles and gloves, proper industrial footwear
Environmental Precautions: Sweep up solid spills to prevent entry to sewers; resin is slowly biodegradable but can cause physical litter
Cleanup Methods: Gather with broom or shovel, use dust suppression if needed, place in suitable container for reuse or disposal
Large Spills: Use mechanical means to recover resin, minimize dust generation, ventilate affected area
Protective Measures: Use local exhaust where dust clouds might form, restrict unprotected personnel from entry

Handling and Storage

Handling: Work in well-ventilated area to reduce dust exposure, use gloves to avoid direct contact
Precautions: Ground all equipment when transferring resin to prevent static discharge; transfer slowly to control dust
Hygiene Measures: Wash hands after handling, avoid contact with eyes and prolonged skin exposure
Storage Conditions: Store in cool, dry place away from heat and ignition sources, avoid sunlight, keep in original container
Container Requirements: Use sealed, dedicated bins or drums; avoid moisture and strong oxidants
Storage Stability: Properly stored resin remains stable for at least two years without significant degradation

Exposure Controls and Personal Protection

Exposure Limits: No established workplace exposure limits for this resin; general dust limits apply (e.g., ACGIH TLV-TWA for particulates not otherwise classified: 10 mg/m³ total, 3 mg/m³ respirable)
Engineering Controls: Use local exhaust to minimize airborne dust and vapor concentrations, provide eyewash stations in areas with transfer or melting
Personal Protection: Wear impervious gloves, safety glasses, dust masks or particulate respirators when dust is present
Protective Clothing: Long sleeves and closed-toed shoes recommended, chemical-resistant apron when handling molten material
Environmental Controls: Ventilation should prevent buildup of vapors above recommended exposure guidelines

Physical and Chemical Properties

Appearance: Pale yellow to water-white solid pellets or beads
Odor: Faint hydrocarbon odor
Melting Point: Ranges from 60°C to 120°C depending on grade
Boiling Point: Not applicable for polymeric material
P/V Ratio: Vapor pressure low, evaporation negligible at ambient
Specific Gravity: 0.97–1.10 (depending on hydrogenation level)
Solubility: Insoluble in water, soluble in aromatic and aliphatic hydrocarbons
Viscosity: Not flowable at room temperature; melts to viscous fluid
Flash Point: Over 250°C (open cup)
Ignition Temperature: Around 405°C
Explosive Properties: Dust forms explosive mixtures with air at high concentrations
Other: No significant pH; non-corrosive to metals

Stability and Reactivity

Chemical Stability: Stable under normal use and storage conditions
Hazardous Reactions: Strong oxidizers (peroxides, nitric acid) can trigger rapid reaction
Conditions to Avoid: Long-term exposure to heat above 150°C, sources of ignition, strong sunlight
Materials to Avoid: Strong acids and oxidizers
Hazardous Decomposition: Thermal breakdown creates carbon monoxide, carbon dioxide, hydrocarbons
Polymerization: Product does not self-polymerize

Dermal Effects: Rare irritation on intact skin, mild inflammation if exposed to molten resin
Inhalation: Dust causes slight respiratory irritation at high concentrations
Eye Effects: Dust, smoke, or fumes may cause redness, tearing, mild discomfort
