Ingestion: Not to expected to be harmful if swallowed. Skin Contact: No information reported, molten material may cause thermal burns, may include pain or feeling of heat, discoloration swelling and blistering. Eye Contact: Not expected to cause prolonged or significant eye irritation. material dusty particle may act as foreign body. If material is heated, thermal burns may result from eye contact. SECTION 4 FIRST AID MEASURES Inhalation: Remove to fresh air. Get medical attention when necessary. Ingestion: If swallowed, do not include vomiting, give the person water or milk to drink and get immediate medical attenetion. Never give anything by mouth to an unconscious person. Skin Contact: IF molten material just contacts skin, remove rapidly and cool with water and seek medical attention if any symptoms develop. If molten or heat material gets on skin, quickly cool in water, see a doctor for extensive burns. Do not try to peel the solidified material from the skin or use solvents or thinners to dissolve the solidified material. May use vegetable oil, mineral oil or petroleum jelly for removal of the material from the skin. 1/5

2 Eye Contact: Flush with copious clear water (eyeswash water). Get medical attention if irritation developed SECTION 5 FIRE FIGHTING MEASURES Flash (piloted) Ignition Temperature: >343 C Method: ASTM D Self-Ignition (non-piloted) Temperature: >371 C Method: ASTM D Fire: Not considered to be a fire hazard. Explosion: Not considered to be an explosion hazard. Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Special Information: In the event of a fire, wear full protective clothing and NIOSHapproved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. SECTION 6 ACCIDENTAL RELEASE MEASURES Spilled product may cause a slipping hazard. When released or spilled, Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. If molten material is spilled, allow it to cool before proceeding with disposal methods. SECTION 7 HANDLING AND STORAGE General Storage Information: Store in a dry and well ventilated area and keep the container closed when not in use. Keep the material away from moisture or humitity environment, heat, sparks OR open flame. Unusual Handling hazards: Potential toxic/irriating fumes may be evolved from molten or heat material. Precautionary Measures: Spilled pellets may create a slipping hazard. Avoid breathing vapors or fume which may be released during thermal processing. Avoid contact of molten or heated material with skin,eye and clothing. SECTION 8 EXPOSURE CONTROL / PERSONAL PROTECTION Eye Protection: Dawnprene general purpose thermoplastic rubber does not cause significant eye irritation or eye toxicity requiring special protection. Use good industrial practice to avoid eye contact. Skin Protection: Although Dawnprene general purpose thermoplastic rubber does not 2/5

3 present significant skin concern; minimize skin contamination by following good industrial hygiene practice. Wearing protective gloves is recommended. Wash hands and contaminated skin thoroughly after handling. Respiratory Protection: Avoid breathing process vapors or dust. Use NIOSH approved respiratory protection equipment (full facepiece recommended) when airborne exposure is excessive. Consult respirator manufacturer to determine appropriate type equipment for given application. Observe respirator use limitations specified by NIOSH or the manufacturer. Ventilation: Provide natural or mechanical ventilation to minimize exposure. If practical, use local mechanical exhaust ventilation at sources of air contamination such as open process equipment. SECTION 9 PHSICAL AND CHEMICAL PROPERTIES Appearance: black color pellets. Odor: Slightly rubberlike. Specific Gravity: 0.97±0.05 Hardness: Shore A ph: No information found. Volatiles by 21C (70F): 0 Boiling Point: Not applicable. Vapor Density (Air=1): No information found. Vapor Pressure (mm Hg): No information found. Evaporation Rate (BuAc=1): No information found. NOTE: These physical data are typical values based on material tested but may vary from sample to sample. Typical values should not be construed as a guaranteed analysis of any specific lot or as specifications for the product. SECTION 10 STABILITY AND REACTIVITY DATA Stability: Thermally stable to 260 C Materials to Avoid: Dawnprene thermoplastic rubber may react with strong oxidizing chemicals. Dawnprene thermoplastic rubber also reacts with acetal resins at temperatures of 218 C and above, producing decomposition of the acetal resin, and formaldehyde as a decomposition product. Decomposition of halogenated polymers and phenolic resins may also be accelerated when they are in contact with Dawnprene thermoplastic rubber at processing temperatures. Thoroughly purge processing equipment with polyolefin polymers, including polypropylene, when using the same equipment to process Dawnprene thermoplastic rubber 3/5

4 and acetal resins, halogenated polymers and phenolic resins. Do not mix Dawnprene thermoplastic rubber, acetal resins, halogenated polymers or phenolic resins at elevated temperatures. Hazardous Decomposition Products: Smoke, carbon monoxide and possibly hydrocarbons may evolve when processing temperatures exceed 260 C or when Dawnprene generalpurpose thermoplastic rubber is ignited. Hazardous Polymerization: Does not occur. SECTION 11 TOXICOLOGICAL INFORMANTION Immediate Health Effects: Acute Oral Toxicity: LD50/ not known Acute Dermal Toxicity: LD50/ not known Acute Inhalation Toxicity: LC50/ not known Eye Irritation: This material is not expected to be irritating to the eyes. Skin Irritation: This material is not expected to be irritating to the skin. Additional Toxicology Information: The toxicological properties of this product have not been tested or have not been tested completely and its handing or use may be hazardous. Long-term exposure to high dust concentrations may cause non-debilitating lung changes. SECTION 12 ECOLOGICAL INFORMANTION Eco-toxicity: The toxicity of this material to aquatic organisms has not been evaluated. Consequently, this material should be kept out of sewage and drainage systems and all bodies of water. Environmental fate: This material is not expected to be readily biodegradable. SECTION 13 DISPOSAL CONSIDERATION When discarded, Dawnprene general purpose thermoplastic rubber is not a "hazardous waste" as that term is defined in 40 CFR 261, "Identification and Listing of Hazardous Waste." Recycle or burn in an approved incinerator or dispose of in an approved chemical landfill in accordance with all applicable local, state and federal laws and regulations. Consult your attorney or appropriate regulatory officials for information on such disposal. 4/5

5 Reprocess only uncontaminated material. Spill or Leakage Procedures: Vacuum or sweep up and place in container for recycle or disposal as recommended above. Containers: Recycle or burn in an approved incinerator or dispose of in an approved chemical landfill in accordance with all applicable local, state and federal laws and regulations. SECTION 14 TRANSPORT INFORMATION This material is considered to be non-hazardous or dangous for land,sea and air transportation. When transported, the material should keep closed in the intact container or standard package and keep away from strong oxidant, high temperature and moisture.
