CAS Number: 9002-88-4
GHS Classification: Not classified as hazardous according to GHS standards
Physical Hazards: Dust or pellets can present a slip hazard; fine dust may generate a combustible dust hazard
Health Hazards: Minimal acute toxicity; molten polymer can cause severe thermal burns
Environmental Hazards: Not readily biodegradable; potential for environmental persistence
Label Elements: No pictogram required, signal word not needed under typical handling
Precautionary Statements: Avoid breathing dust; prevent contact with hot molten material; keep away from ignition sources
Potential Adverse Human Health Effects: Fumes from thermal decomposition or combustion may trigger irritation or respiratory symptoms
Chemical Name: Polyethylene, Metallocene Blend
CAS Number: 9002-88-4
Concentration: 98-100% polyolefin content
Additives: Trace stabilizers, antioxidants, possible colorants, less than 2% vary depending on grade
Hazardous Components: Contains no regulated hazardous ingredients at concentrations requiring disclosure
Impurities: Minor catalyst residues, under one part per million
Inhalation: Move person to fresh air if dust, fumes, or combustion gases affect breathing
Eye Contact: Rinse eyes thoroughly with water; seek medical attention if irritation persists or for burns caused by molten polymer
Skin Contact: Remove contaminated clothing and rinse skin with water; for burns from hot polymer, seek immediate medical attention and avoid removing material adhering to burned skin
Ingestion: Unlikely under ordinary use; wash out mouth, consult a physician if symptoms develop
Most Important Symptoms: Slight irritation or redness for solid dust contact; burning sensation or severe injury if exposed to hot melt
Suitable Extinguishing Media: Water spray, foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Direct high-pressure water jet may spread molten resin
Specific Hazards: Upon combustion, produces carbon monoxide, carbon dioxide, and potentially toxic fumes
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus
Special Fire-Fighting Measures: Avoid inhaled fumes; cool exposed containers with water spray to prevent rupture
Explosion Hazard: Fine dust suspended in air may create an explosive dust atmosphere
Personal Precautions: Wear gloves, goggles, and protective clothing to prevent skin or eye contact with hot material or dust
Environmental Precautions: Prevent pellet or powder release into drains, waterways, or soil
Methods for Cleaning Up: Sweep, shovel, or vacuum spilled material and place in suitable containers; clear small quantities with industrial vacuum cleaners equipped with explosive-proof motors
Other Recommendations: Use slip-prevention signage to warn others around releases
Handling: Minimize generation of dust and handle away from ignition sources; avoid breathing dust or fumes; exercise caution around hot machinery
Storage: Store in dry, cool, well-ventilated location away from direct sunlight and sources of heat or flame
Incompatible Materials: Strong oxidizing agents can react violently with polyolefins
Safe Handling Advice: Install grounding and bonding for dust control; employ local exhaust at heated process points
Container Requirements: Use dedicated, labeled containers to prevent contamination or accidental mixing
Exposure Limits: No established occupational exposure limits for bulk polyethylene; monitor workplace for nuisance dust
Engineering Controls: Local exhaust ventilation recommended at locations of heated resin processing
Respiratory Protection: Dust mask or respirator for airborne dust or processing fumes
Skin Protection: Wear gloves and long-sleeves for protection from hot resin
Eye Protection: Safety goggles with side shields or face shield
General Hygiene: Wash hands after handling; do not eat, drink, or smoke in processing areas
Appearance: Translucent to white granules, pellets, or powder
Odor: Slight waxy odor
pH: Not applicable
Melting Point: 120–135°C, varying with resin grade
Boiling Point: Not applicable

Density: 0.915–0.965 g/cm³
Partition Coefficient (n-octanol/water): Not determined
Decomposition Temperature: Above 300°C
Chemical Stability: Stable under ambient storage and handling conditions
Hazardous Reactions: No hazardous polymerization takes place under normal conditions
Reactive Materials: Strong oxidizers including peroxides, acids, chlorine; hazardous decomposition may occur
Conditions to Avoid: Open flame, high temperatures, exposure to sunlight over long periods
Decomposition Products: Burns or decomposes to form carbon monoxide, carbon dioxide, water, and trace organic vapors
Acute Toxicity: LD50 oral and dermal: not acutely toxic in standard animal models
Irritation: Minimal irritation in skin or eye contact with solid material; severe with molten resin
Inhalation Hazard: Fumes and combustion products cause respiratory irritation
Chronic Effects: No significant long-term toxicity observed in occupational exposure
Sensitization: Not expected to cause allergic reactions
Carcinogenicity: No evidence of carcinogenic activity from polyethylene precursors or dust
Persistence and Degradability: Polyethylene is not readily biodegradable; persists in soil and aquatic environments
Bioaccumulation Potential: Low according to available studies; very low water solubility limits uptake
Mobility in Soil: Pellets and powders are physically mobile, especially in waterways
Ecotoxicity: No acute toxicity expected for aquatic organisms at environmental concentrations; physical effects possible if ingested by wildlife
Other Adverse Effects: Major environmental concern involves litter and marine plastics accumulation
Waste Disposal: Recover and recycle where possible; disposal by incineration with energy recovery or permitted landfill for non-recyclable residues
Container Disposal: Uncontaminated containers may be reused or recycled; contaminated packaging requires designated industrial waste management
Special Precautions: Prevent pellet loss to the marine environment; comply with local, regional, and national waste regulations
UN Number: Not regulated for transport
Transport Hazard Class: Not classified as dangerous goods
Packing Group: Not assigned
Environmental Hazards: Polyethylene granules or dust can constitute slip or litter hazards if released
Special Transport Precautions: Containers must be securely closed and dry; minimize risk of package breakage and pellet spillage
