Section 2. Composition/Information on Ingredients

Ingredients: Ingredient CAS Number

Base Resin 30965-26-5

This is a polymeric material. All constituents are wetted by the polymer system, and therefore, present no likelihood of exposure under normal conditions of processing and handling.

This product contains proprietary ingredients.

While this product is not classified as hazardous under OSHA Regulations, this MSDS contains valuable information critical to the safe handling and proper use of the product. This MSDS should be retained and made available for employees and other users of the product.

This product is not regulated by WHMIS.

Section 3. Hazards Identification

Emergency Overview: Pellets or chips with slight to no odor. Combustion and decomposition may produce hazardous fumes. Base resin dust/powder has a US Bureau of Mines relative dust explosion hazard rating of weak. Molten material can cause thermal burns on contact with skin or eyes. Spilled pellets may create a slipping hazard.

Potential Health Effects:

Routes of Exposure: Skin and eye contact. Inhalation of vapors.

Signs and Symptoms of Exposure: No specific information available.

Immediate Effects:

Skin: No specific information available on the product. Hot or molten material has the potential to cause thermal burns. Polymer particles can cause mechanical irritation.

Eyes: No specific information available on the product. Polymer particles can cause mechanical irritation. Degradation vapors may cause irritation.

Inhalation: No specific information available on the product. In the form supplied, this material is not considered an inhalation hazard; polymer particles may be considered an inert nuisance particulate. Overheating in processing may generate hazardous, irritating vapors.

Ingestion: No specific information available on the product; however, low toxicity by this route is expected based on the biological activity of high molecular weight polyesters.

Long Term/Delayed Effects: No specific information available.

Carcinogenicity: No specific information available on the product. The International Agency for Research on Cancer (IARC) has evaluated carbon black, which may be contained in this product, and found it to be possibly carcinogenic to humans (Group 2B). Any carbon black in this product is wetted by the polymer system, and therefore, presents minimal likelihood of exposure under normal conditions of processing and handling.

Medical Conditions Aggravated By Exposure: No specific information available on the product. Off-gases, which may be released if overheated, may affect those with chronic diseases of the respiratory system.

Section 4. First Aid Measures

Skin: If hot or molten polymer of hot vapors contact skin, cool rapidly with cold water. If polymer is stuck to skin, do not remove. Seek medical attention. Allow adhered polymer to come off naturally. Removal of adhered polymer may result in more tissue damage than if polymer is allowed to come off over time.

Eyes: Flush with plenty of water. Seek medical attention if discomfort persists, and to remove foreign body.

Inhalation: Remove to fresh air. Seek medical attention if difficulties in breathing occur.

Ingestion: If a significant quantity has been swallowed, give two glasses of water to dilute. Seek medical attention.

Note to Physicians: This product is essentially inert and nontoxic. However, if it is heated at too high a temperature or if it is burned, gases may be released (see Sections 5 and 10 for off-gases). Patients who have been exposed to off-gases may need to have their arterial blood gases and carboxyhemoglobin levels checked. If the carboxyhemoglobin levels are normal, asphyxia (carbon dioxide replacing oxygen) is a possibility. As with any fire, irritant gases may have formed. If patients may have inhaled high concentrations of irritating fumes, they should be monitored for delayed onset pulmonary edema.

Section 5. Fire Fighting Measures

Flashpoint: >93 deg C (>200 deg F) by Tag Closed Cup Method.

Base resin dust/powder has a US Bureau of Mines relative dust explosion hazard rating of weak.

Hazardous Products

Of Combustion: Carbon monoxide and carbon dioxide.

Extinguishing material: Water spray, foam, carbon dioxide, or dry chemical.

Firefighting Instructions: Firefighters should wear self-contained breathing apparatus and full fire-fighting turn-out gear (bunker gear). Keep personnel removed from and upwind of fire. Water should be used to keep fire-exposed containers cool. Water, foam and dry chemical may cause damage to electrical equipment.

Section 6. Accidental Release Measures

*For more information, see regulatory section 15.

Procedures in Case

Of Spill or Leak: Sweep or gather up spills and place in proper container for recovery or disposal. Ticona supports SPI’s Operation Clean Sweep.

Section 7. Handling and Storage

Handling: Do not handle hot or molten material without appropriate protective equipment. Maintain good housekeeping in work areas. Do not exceed recommended process temperatures to minimize release of decomposition products. Do not smoke in areas where polymer dust is present. Appropriate measures should be taken to control the generation and accumulation of dust during conveying and processing operations.

Storing: Store in a cool dry place. Maintain dryness of resin.

Section 8. Exposure Controls/Personal Protection

Engineering Controls: Local Exhaust: Recommended when appropriate to control employee exposure to dust or process vapors.

General: May not be adequate as the sole means to control employee exposure.

Protective Equipment:

Skin: When thermal or melt processing, wear long pants, long sleeves, well insulated gloves, and face shield when there is a chance of contact.

Eyes: Safety eyewear recommended.

Inhalation: A NIOSH approved respirator is recommended if there is a possibility of dust generation above permissible exposure limits or that decomposition vapors may be generated.

Exposure Guidelines: Operations involving grinding and machining of parts should be reviewed to assure that particle levels are kept below recommended standards.

This product may contain carbon black. See the exposure limits below.

Section 11. Toxicological Information

No specific information available on the product.

Inhalation of carbon black, a possible ingredient, has been shown to cause lung tumors in rats at high exposure concentrations. These concentrations appear to exceed the capacity of the lung to clear the carbon black particles, thus resulting in significant toxicity.

Section 12. Ecological Information

Ecotoxicity: The effects of resin pellets on the wildlife that may ingest them is not well understood. In the case of seabirds, some marine biologists believe that the fowl may not be able to pass plastic pellets through their digestive tracts. Thus, large quantities of ingested pellets may cause intestinal blockage, false feelings of satiation or reduction in absorption of nutrients, causing malnutrition and starvation. The goal of PSI’s Operation Clean Sweep is zero loss of pellets into the environment.

Section 13. Disposal Considerations

Disposal: Recycling is encouraged. Incinerate or landfill in accordance with federal, state, and local regulations. This product, as shipped, is not a RCRA hazardous waste under present EPA regulations.

Section 14. Transport Information

Not regulated under US Department of Transportation.

Section 15. Regulatory Information

TSCA: All the components of this product comply with TSCA Regulations. This product contains traces of tetrahydrofuran, which is a TSCA 12b chemical. TSCA 12b requires notifying EPA prior to export.

SARA: This product does not contain any toxic chemicals subject to the reporting requirements of Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 and of 40 CFR 372.
