PHYSICAL / CHEMICAL PROPERTIES Physical Form: Solid Color: Finished sheets with colors specified Odor: Insignificant Boiling Point: Not applicable Melting Point: 150-170°C Freezing Point: Not applicable Solubility in Water: None Specific Gravity: 0.7-1.2 (water = 1) Vapor Density: Not applicable (air = 1) Evaporation Rate: None (Butyl Acetate = 1) Vapor Pressure: Not applicable % Volatile: None pH: Not applicable The physical data presented above are typical values and should not be construed as a specification. 4. FIRE HAZARD DATA AND FIGHTING METHOD Flash Point: Not applicable Autoignition: Not applicable Flammable Limits In Air (LEL, %) Not applicable (UEL, %) Not applicable Extinguishing Media: Dry chemical, carbon dioxide or foam 1 Special Fire Fighting Procedure: Thermal decomposition may occur at temperatures greater than 390°C. In the event of a fire, wear NIOSH approved, positive pressure, self-contained breathing apparatus (SCBA) and full protective clothing. Extinguish fires with foam or dry chemical. Do not use water jet. Unusual Fire and Explosion Hazards: Avoid accumulation and dispersion of dust to reduce explosion potential. Fire may produce irritating gases and dense smoke. 5. HUMAN HEALTH DATA Emergency Overview: Practically nontoxic

Principle Routes of Exposure

Inhalation, Eye, Skin Contact

Potential health effects

and Symptoms of Over-Exposure Negligible hazard at room temperature under normal use. Eye Contact: Solid flake or dust may cause transient irritation as a result of mechanical abrasion. Skin Contact: Essentially no irritation to skin. Mechanical injury only. Hot solid may cause thermal burns. Inhalation: Exposure to dust at high concentration may cause irritation to respiratory tract. Ingestion: May cause choking if swallowed.

Medical Conditions Generally Aggravated by Exposure

Overexposure: Not expected. IntePro is generally accepted as being biologically inert. No specific antidotal treatment, symptomatic support required. Carcinogenicity: NTP: No IARC: No OSHA: No 6. FIRST AID MEASURES Eye Contact: Immediately flush eyes with water for at least 15 minutes. Do not rub the eyes. If irritation or other symptoms occur, consult a physician. Skin Contact: Get medical attention for serious burns. In case of skin contact with hot IntePro, immediately immerse in or flush with clean, cold water. Inhalation: Remove to fresh air. Consult physician if irritation or respiratory passage occurs. Ingestion: Consult physician. Notes to Physician: No known delayed effects following single exposure. Other Instructions: None 7. EXPOSURE CONTROLS, PERSONAL PROTECTION RECOMMENDATIONS Eye Protection: Safety glasses Skin Protection: Gloves required when handling hot material Respiratory Protection: None required in normal use of product. NIOSH approved dust mask recommended if dust conditions exist. Engineering Control: Ventilation Requirements - General 2 General ventilation should be sufficient. However, if operating conditions create high airborne concentrations of this material, special ventilation may be needed. If handling results in dust generation, special ventilation may be needed to ensure that dust exposure does not exceed the OSHA PEL for nuisance dust. Required Work/Hygiene Procedure: Minimize contact with skin. Do not eat, drink or smoke in work area. Wash hands thoroughly after handling, especially before eating, drinking, smoking, chewing or using restroom facility. Dusted clothing and shoes should be thoroughly cleaned before use. Exposure Guidelines: No. Components OSHA-PEL ACGIH-TLV 1 Polypropylene Copolymer None Nuisance dust: 10 mg/M³ TWA 8. ACCIDENTAL RELEASE CONTROL MEASURES Response to Spills: Not applicable 9. HANDLING AND STORAGE Handling: Wear safety glasses during cutting and fabricating process. Electrostatic charge may build up during handling. Grounding of equipment is recommended.

Storage

Store in a dry place and away from direct sunlight. Container Use: Keep container closed. 10. STABILITY AND REACTIVITY Stability: Stable Conditions to Avoid: Strong oxidizers Hazardous Decomposition: Carbon dioxide, carbon monoxide Hazardous Polymerization: Will not occur 11. DISPOSAL CONSIDERATIONS Disposal Method: It must be disposed of in accordance with Federal, State and local environmental control regulations. Recycle/Reclaim: Recycling and reclamation of IntePro should be encouraged where possible. 12. TRANSPORT INFORMATION DOT Shipping Name: Not listed DOT Label: Not regulated DOT Hazard Class: Not applicable UN/NA Number: Not applicable Hazard Label(s): Not applicable 3 Hazard Placard(s): Not applicable Packing Group: Not applicable Bulk Packaging: Not applicable RQ: Not applicable Emergency Response Guide (ERG) No.: Not applicable 13. TOXICOLOGICAL INFORMATION The information provided below can be subject to misinterpretation. Therefore, it is essential the following information be interpreted by individuals trained in its evaluation. Chemical Toxicity Data Polypropylene copolymer No toxicology data available Polypropylene is not considered hazardous materials under the OSHA Hazard Communication Standard 14. ECOLOGICAL INFORMATION No data is available on the adverse effects of this product on the environment. Neither COD or BOD data are available. 15. REGULATORY INFORMATION FEDERAL REGULATORY INFORMATION Polypropylene copolymer OSHA Status: None EPA Clean Air Act Status: None EPA Clean Water Act Status: None TSCA Status: All ingredients are listed on TSCA Inventory (40 CFR710) CERCLA RQ: None SARA Title III Polypropylene copolymer Section 311/312*** None *Reportable quantity of extremely hazardous substance, Sec 302 * Threshold planning quantity, extremely hazardous substance, Sec 302 ** Toxic chemical, Sec 313 ** Category as required by Sec 313 (40CFR372.65C). Must be used on Toxic Release Inventory form. *** Hazard category for SARA Sec. 311/312 reporting H1=acute health hazard, H2=chronic health hazard, P3=fire hazard, P4=sudden release of pressure hazard, P5=reactive hazard. RCRA Status: If disposed of in its purchased form, this would not be a RCRA hazardous waste either by listing or by characteristic. However, under RCRA, it is the responsibility of the product used to determine at the time of disposal whether a material containing the product or derived from the product should be classified as a hazardous waste (40CFR261.20-24). OTHER REGULATORY INFORMATION The following chemicals are specifically listed by individual states; other product-specific health and safety data in other sections of the SDS may also be applicable for state requirements.
