Hazard Identification

Health Hazards: Breathing dust or fumes for long periods can leave headaches, irritation, drowsiness, nausea, or lightheadedness. Prolonged skin contact can cause dryness, redness, and possible cracking. Eyes become irritated and water when exposed.

Precaution Phrases: Avoid breathing dust; keep away from ignition sources; work in a well-ventilated space; use gloves and safety glasses

Composition / Information on Ingredients

Main Component: Dicyclopentadiene polymer (70–95%)
Impurities: Cyclopentadiene oligomers, formaldehyde, traces of aromatics, light hydrocarbons
Additives: Small stabilizers, sometimes oil or wax for processing (up to 6%)
Residual Monomers: Less than 1% dicyclopentadiene, cyclopentadiene, pentadiene
Other Ingredients: Inhibitors (trace), proprietary modifiers (if present, supplier-specific)

First Aid Measures

Inhalation: Shift to fresh air if fumes overwhelm or dizziness comes on. Remove contaminated clothing if needed. Seek medical help if symptoms stick.
Skin Contact: Wash area with water and mild soap right away. If rash develops, see a doctor.
Eye Contact: Rinse with clean water for at least 15 minutes while keeping eyelids apart. Medical attention needed if redness or pain stays.
Ingestion: Rinse mouth with water. Don’t try to throw up. Go to a physician at once for advice.
Special Note: Bring product label and MSDS with you for emergency room visits

Fire-Fighting Measures

Suitable Extinguishing Media: Use water fog, foam, dry chemical, or CO2 to douse the flames.
Unsuitable Media: Avoid straight water stream—may scatter burning product.
Special Hazards: Fumes and smoke from burning resin may carry toxic or irritating chemicals including carbon monoxide, carbon dioxide, hydrocarbons.
Protective Equipment: Full protective suit, SCBA needed for firefighters.
Special Instructions: Cool exposed containers as pressure build-up can cause rupture.
Explosion Risk: Fine dust or powder from grinding or sanding can blow up in air if heated or sparked

Accidental Release Measures

Personal Precautions: Wear gloves, goggles, dust mask for powders. Air out the area if vapors collect.
Environmental Precautions: Stop resin from entering drains or bodies of water. Sandbags or absorbent works for spills.
Spill Clean-Up: Scoop up loose resin or mop up with absorbent. Seal in drums for waste contractor. Ventilate closed spaces.
Disposal Note: Use methods that prevent dusty conditions and minimize health risks for workers.

Handling and Storage

Handling Guidelines: Keep away from spark sources, flames, hot surfaces. Use local exhaust if dust or vapor builds up. Limit skin contact, wash up after shifts, no smoking.
Storage Requirements: Store resin in sealed, labeled containers in cool, dry spot out of sunlight. Stack bags or drums safely.
Incompatible Materials: Strong oxidizers, acids, direct heat, open flame, sources of ignition.
Special Instructions: Keep fire extinguishers handy in work areas.

Exposure Controls and Personal Protection

Exposure Limits: No formal regulatory limit for dicyclopentadiene resins, but minimize dust/vapor to below recommended safe levels (ACGIH TLV for hydrocarbon compounds: 5 mg/m3 for particulates).
Engineering Controls: Ventilation fans, fume hoods, dust extraction around process areas.
Personal Protective Equipment: Nitrile gloves, safety goggles, coveralls, and work boots. Use a dust mask or respirator if handling powder or sanding, especially in close spaces.
Hygiene Measures: Wash hands before eating or drinking. No food or drink allowed where product handled.

Physical and Chemical Properties

Physical State: Solid resin, typically as flakes, beads, granules, or chunks
Color: Pale yellow to amber
Odor: Slight hydrocarbon smell, sometimes sweet or sharp
pH: Not applicable
Melting Point: 80–135°C (depends on grade)
Boiling Point: Decomposes before boiling
Flash Point: Around 230°C closed cup, lower if mixed with oil
Auto-Ignition Temperature: 400°C and above
Explosion Limits: Dust may explode in air
Vapor Pressure: Low at room temperature

Stability and Reactivity

Chemical Stability: Stays stable under recommended usage and storage. Runs into trouble near open fire, heat, or oxidizers.
Reactivity: Combusts with strong oxidizing chemicals or under high heat.
Conditions to Avoid: Direct sunlight, sparks, hot surfaces, open flames, static electricity
Incompatible Materials: Peroxides, chlorine, nitric acid
Hazardous Decomposition: Fumes of carbon monoxide, carbon dioxide, small hydrocarbons can form upon burning.

Toxicological Information

Acute Health Effects: Breathing dust or fumes can cause headaches, throat and lung irritation, sometimes coughing and nausea. Skin itching, dryness, and cracking appear after enough contact. In rare cases, allergic skin reaction may develop.
Chronic Health Effects: Long-term overexposure may dry out or injure skin, worsen asthma or chronic bronchitis, and aggravate symptoms for folks with allergies.
Ingestion: Accidental swallowing brings upset stomach, in larger amounts headache, nausea, and risk of CNS depression.
Carcinogenicity: Neither IARC nor OSHA lists dicyclopentadiene resin as a confirmed carcinogen; impurities might vary.
Mutagenicity: No evidence from available animal tests that resins result in genetic defects.
Other Information: Dicyclopentadiene monomer vapor is more toxic than resin, but only trace levels present in finished resin.

Ecological Information

Ecotoxicity: Finished resin doesn’t break down quick in water, clumps together, sinks, affects aquatic creatures if released in bulk; fish, daphnia, and algae most at risk.
Persistence and Degradability: Not rapidly biodegradable; hangs around in soil or sediment for long stretches.
Bioaccumulation: No strong evidence these resins build up in animal tissue.
Mobility in Soil: Resin pieces or dust won’t travel far but can get into sediment if washed away.
Other Info: Spills form solid lumps, don’t dissolve, but fine particles stress sewage systems and water plants.

Disposal Considerations

Waste Treatment: Solid scrap goes to licensed landfill or waste incinerator, following local rules.
Container Disposal: Empty bags or drums should be scraped clean and recycled or trashed per council or state law.
Precautions: Never burn in open pit—use permitted incinerators; avoid dumping in drains or natural water.
Regulatory Notes: Waste classified as non-hazardous in small quantities but local regulations vary

Transport Information

UN Number: None assigned for solid resin, classified as non-hazardous unless hot or molten
