Thermoset Polyurethane Elastomer

Signal word

EMERGENCY OVERVIEW PHYSICAL APPEARANCE: Solid rubbery like material. IMMEDIATE CONCERNS: Burning gives off toxic fumes. Slippery especially when wet. Dusts from grinding operations may aggravate existing lung disorders when proper protection is not used. OSHA Hazard Communication Standard: Polyurethane elastomers are fully reacted polymers forming articles which are not considered “Hazardous” under normal use as defined by OSHA Hazard Communication Standard, 29 CFR 1910.1200 However, hazardous dusts, vapors, gases and fumes may be released by mechanical or thermal processing by thermal decomposition.

Potential health effects

EYES: Not affected during normal use. SKIN: Not affected during normal use. INGESTION: Not affected during normal use. INHALATION: Inhalation of dust during machining and inhalation of vapors during hot wire cutting or branding can be irritating and lead to coughing. Fumes can contain traces of isocyanates such as MDI or TDI, carbon monoxide, oxides of nitrogen, and traces of hydrogen cyanide. SIGNS AND SYMPTOMS OF OVEREXPOSURE EYES: Not effected during normal use. SKIN: Not effected during normal use. INGESTION: Possible nausea and/or vomiting. INHALATION: Not effected during normal use. Use NIOSHA approved respirator for any grinding or burning operation. For grinding wear a dust respirator. If generating gas by grinding, cutting, or thermal processing wear an air - purifying respirator with organic cartridge or supplied – air respirator if ventilation is inadequate. ACUTE TOXICITY: No test data is available for acute dermal toxicity. Not expected to cause significant adverse effects if ingested. No test data is available for acute inhalation toxicity. CHRONIC TOXICITY: Animal studies indicate that chronic inhalation or overexposure of dust may cause inflammation of the lungs, fibrosis, and airway destruction. CARCINOGENICITY: Cured polyurethane is not listed as a carcinogen Not Listed by NTP Not listed by IARC Not listed by OSHA MUTAGENICITY: Not Available REPRODUCTIVE TOXIN REPRODUCTIVE EFFECTS: Not Available

Teratogenic Effects

Not Available

Medical Conditions Generally Aggravated by Exposure

None known under normal use TARGET ORGAN STATEMENT: None known under normal use SENSITIZATION: Fumes could contain trace amounts of MDI isocyanates and or curatives. Repertory or skin exposure may produce an asthma-like lung sensitization.
