Emergency overview:
This material is not hazardous by OSHA Hazard Communication
Definition
Signal Word
CAUTION!
Physical Health Hazards:
Dust may form explosive mixtures with air. Molten polymer may
cause thermal burns. Irritating fumes may be produced at process
temperatures.
Physical state: Solid
Color: Translucent to white
Odor: Faint, mild hydrocarbon odor
Odor threshold: No data available
Potential Health Effects:
Routes of exposure
Eye contact, ingestion, skin contact
Signs and Symptoms of Acute Exposure:
For polyethylene homopolymer: Molten polymer may cause thermal
burns. At process temperatures, irritating fumes may cause
soreness in the nose and throat, coughing may result. Mechanical
irritation is possible.
Skin contact:
Molten polymer may cause thermal burns
Inhalation:
At process temperatures irritating fumes may be produced.
Inhalation of process fumes may cause soreness in the nose
and throat and coughing. Inhaling polyethylene dust is
considered a nuisance.
Eye contact:
Mechanical irritation is possible
Ingestion:
Ingestion is unlikely
Chronic Health Effects Summary:
No known chronic health effects.
Polyethylene Homopolymer:
Conditions Aggravated by Exposure:
No known conditions are aggravated by this material.
Take proper precautions to ensure your own health and safety before
attempting to rescue and providing first aid. For specific information
refer to the Emergency Overview in Section of this MSDS.
Inhalation: If symptoms are experienced, move victim to fresh
air, if symptoms persist, obtain medical attention.
Eye Contact: Wash eyes with clean low-pressure water. If
irritation persists, seek medical advice.
Skin Contact: If molten material contacts the skin, immediately
flush the skin with large amounts of water to cool
the affected tissue and polymer. Do not attempt to
peel polymer from skin. Get medical attention
immediately.
Ingestion: Adverse health effects due to ingestion are not
anticipated. If gastric irritation or discomfort
persists, seek medical advice.
Flammability classification:
Not classified. Polymer will burn but does not ignite readily.
Flash Point/Method: Not applicable
Auto-Ignition Temperature: 343°C (650°F)
Flammable Limits: Lower: Not applicable
Upper: Not applicable
Hazardous Combustion Products:
Carbon monoxide, olefinic and paraffinic compounds, trace amounts
of organic acids, ketones, aldehydes and alcohols may be formed.
Special Conditions to Avoid:
Polyolefin dust particles in the atmosphere are combustible and
may be explosive. Keep away from heat, sparks, flame and all
other ignition sources. Keep container closed. Clean up dust
accumulations. Prevent dust accumulations and dust clouds,
[Note: Processes using spray application or fluidized bed
operation should be in accordance with NFPA 33 "Standard for
Spray Applications Using Flammable and Combustible Materials."
Extinguishing Media:
Small fires: Use dry chemicals, CO2, water spray.
Large fires: Use dry chemicals, CO2, water spray.
Fire Fighting Instructions:
Protective Equipment/Clothing: Wear a NIOSH approved positive
pressure self-contained breathing apparatus and firefighter
turnout gear.
Instructions: Use flooding quantities of water until well after
fire is out.
Release response:
Pick up and retain for recycle or disposal. Do not flush
spilled material to the sewer or the environment.
Reportable Quantities: See Section 15: Regulatory information.
Handling: The handling of powder in both loading and unloading operations as well as fabrication may cause dust to be formed, and necessary precautions for personal protection (see Section 8) should be used . As with all finely divided materials, precautions should be taken to avoid inhalation and eye contact. Transfer from storage with a minimum amount of dusting. Ground all transfer, blending, and dust collecting equipment to prevent static sparks in accordance with NFPA 70 "National Electric Code." Remove all ignition sources from material handling, transfer, and processing areas where dust may be present. Local exhaust ventilation should be provided in work areas. Ensure that airborne dust concentrations are controlled within acceptable OSHA dust standards. If material is used in spray or fluidized bed operations, see Section 5 of this MSDS for additional information. Storage: Keep container dry. Store away from excessive heat and away from strong oxidizing agents. Keep container closed to prevent contamination.
Engineering Controls: If user operations generate dust or fumes,
ventilate area to prevent accumulation.
Personal Protection:
Inhalation: Use appropriate respiratory protection where atmosphere
exceeds recommended limits. Total Dust (PNOC): ACGIH 10 mg/M3,
OSHA 15 mg/M3. Respirable Dust(PNOC) ACGIH 3 mg/M3, OSHA 5 mg/M3.
Skin: Protective clothing such as long sleeves or a lab coat should
be worn. When handling heated materials, also be sure to use heat-resistant
gloves, boots and face protection.
Eye: Always use safety glasses, even for work with small quantities,
such as the making of positive replicas.
Boiling Point/Range: Not applicable
pH: Not applicable
Vapor Pressure: Not applicable
Viscosity: Not applicable
Specific Gravity:
Solid/Liquid 0.91 - 0.98 (water = 1)

Water solubility: Insoluble
Octanol/Water Partition Coefficient in Kow: Specific value not known
Melting/Freezing Point: 104-138°C (219-280°F)
Evaporation Rate: Not applicable
Chemical Stability: The product is stable Conditions to Avoid: Avoid contact with strong oxidizers, excessive heat, sparks or open flame or dust accumulation. Incompatibility with: Chlorine, fuming nitric acid and strong oxidizing agents. Hazardous Products of Deposition: Not expected to decompose under normal conditions. Reactions with Air and Water: Does not react with air, water or other common materials.
Summary: Not considered to be toxic to humans or animals
Component:
Polyethylene homopolymer
LC50 (INHL): Mouse 12 gm/m3/30M
Skin Effects: No skin effects are expected from polyethylene
contact.
Acute Oral Effects: Animal studies showed no adverse health effects
on the digestive system when fed up to 20% polyethylene.
Acute Inhalation Effects: Rats inhaling polyethylene dust developed
mild inflammatory changes in the lungs. Prolonged inhalation of thermal
degradation products from polyethylene caused neurological effects in rats.
Subchronic Effects: Subchronic, 50-90 day, feeding studies conducted
on rats, dogs, and swine showed no effects from dietary levels of 1 to 20%
powdered and shredded polyethylene. IARC has listed polyethylene as a Group
3 substance (not classifiable as to carcinogenicity to humans).
Chronic Effects/Carcinogenicity:
None expected
Reproductive/Development Effects:
No reproductive or developmental effects are expected.
Exotoxicity: Exotoxicity is expected to be low based on the low water solubility of polymers. Environmental Fate: No information found in our selected references. Bioaccumulation: Not expected to occur.
This material is NOT classified as a hazardous material by RCRA. Use only licensed transporters and permitted disposal facilities and conform to all laws. Recycle to process, if possible.
