The MSDS (Material Safety Data Sheet) for plastic particles is the core document for conveying product safety and environmental information and must comply with the Globally Harmonized System (GHS) standards. The following highlights the characteristics of plastic pellets:
I. Basic Information (Section 1: Identification)
1. Product Identification
- Full name of plastic pellets (e.g., polypropylene recycled pellets), trade name, CAS number
- Key additives: flame retardants, masterbatches, plasticizers, etc. (a warning is required if phthalates are present)
2. Supplier Information
- Manufacturer/supplier name, address, and emergency contact number (24-hour)
- Example:
> *Emergency number: +86-XXX-XXXX-XXXX (China) / +1-XXX-XXX-XXXX (International)*
II. Hazard Classification (Section 2: Hazards Identification)
1. GHS Classification Label
- Pictogram (e.g., flammable liquid, health warning)
- Signal word ("Danger" or "Warning")
- Hazard statements (H phrases, e.g., H315: Causes skin irritation)
2. Plastic-specific risks
- High-temperature melting burns, dust explosion (particles ≤500μm must be labeled)
- Risk of toxic gas release (e.g., overheating of PVC particles to release hydrogen chloride)
III. Composition/Information on Ingredients
| Ingredient Type | Disclosure Requirements
| Polymer Base | Must be disclosed (e.g., PE, PET, ABS, etc.)
| Additives/Adjuvants | Hazardous ingredients present at a concentration ≥ 0.1% must be listed
| Confidential Ingredients | Indicate functional category and hazard (e.g., "organotin stabilizer")
IV. Emergency Measures (Section 4: First Aid Measures)
- Inhalation of dust: Remove to fresh air. Seek medical attention if coughing persists.
- Skin Contact: Rinse with soap and water. If burns occur from molten material, cool immediately and seek medical attention.
- Eye Contact: Rinse with running water for 15 minutes.
- Ingestion: Do not induce vomiting. Drink plenty of water and seek medical attention immediately.
V. Firefighting Measures (Section 5: Fire-Fighting Measures
1. Applicable Extinguishing Media: Dry powder, carbon dioxide, foam (water jets are prohibited for dust impact).
2. Pyrolysis Hazards:
- Combustion of PE/PP releases CO and formaldehyde.
- Combustion of PVC releases hydrogen chloride (an alkaline neutralizer is required).
3. Firefighter Protection: Self-Contained Breathing Apparatus (SCBA) + Chemical Protective Clothing.
VI. Accidental Release Measures
1. Small-Scale Spills:
- Collect with anti-static tools and place in a sealed container.
- High-pressure air sweeping is prohibited (to prevent dust cloud explosions).
2. Large-Scale Spills:
- Designate an exclusion zone and cover with dust suppressants (e.g., water-based resin).
VII. Handling and Storage
| Key Operational Points | Storage Requirements
| Local exhaust ventilation (dust concentration ≤ 10 mg/m³) | Store in a cool, dry place away from heat sources and oxidizers.
| Anti-static grounding (resistance ≤ 10⁶Ω) | Stack height ≤ 3 meters, maintain aisle spacing ≥ 1 meter
| Wear dust mask (N95 grade) | Store separately from strong acids and alkalis
VIII. Exposure Controls (Section 8: Exposure Controls/Personal Protection)
1. Engineering Controls:
- Closed feeding system, dust collector (efficiency ≥ 99%)
2. Personal Protection Equipment (PPE):
- Respiratory system: Particulate filter cartridge (P2 grade)
- Body protection: Anti-static overalls + heat-resistant gloves (for handling molten material)
IX. Physical and Chemical Properties (Section 9: Physical and Chemical Properties)
| Parameters | Typical Values (PP Granules)
| Appearance | White/transparent cylindrical granules
| Melting Point | 160-165°C
| Bulk Density | 0.45-0.55 g/cm³
| Dust Explosion Limit | 30g/m³ (particle size ≤ 100μm)
X. Stability and Reactivity (Section 10: Stability and Reactivity)
- Stability: Stable at room temperature, thermally decomposes above 260°C
- Materials to Avoid: Strong oxidizing agents (e.g., nitric acid → flammable), ultraviolet light (light stabilizer effectiveness must be indicated)
- Hazardous Decomposition Products: CO, hydrocarbon VOCs (at temperatures > 300°C)
XI. Other Core Sections
- Toxicology (Section 11):
Acute inhalation toxicity (LD₅₀ > 5,000 mg/kg), Microplastic Bioaccumulation Assessment
- Ecology (Section 12):
Marine Toxicity Data (Degradability must be indicated: e.g., "90-day degradation rate ≥ 60%" for PLA pellets)
- Disposal (Section 13):
Recycling Code (e.g., "♳" for PET pellets) + Non-recyclable waste must be sent to a professional incinerator
- Transport Information (Section 14):
UN Number (e.g., UN 2211, polyolefin granules), Ocean Shipping Ems Code (F-A, S-F)
- Regulatory Information (Section 15):
EU REACH (SVHC List), China's "New Pollutants Control Action Plan" Compliance Statement
- Other Information (Section 16):
Revision Date (2025 version must include Microplastics Directive EU 2025/XXX), Disclaimer
