Health hazards
IDENTIFICATION OSHA ACUTE OR IMMEDIATE EFFECTS/ROUTES OF EXPOSURE: SKIN: Molten acetal may cause thermal burns. EYES: Contact with powder or dust may cause mechanical irritation. INHALATION: Shapes are not considered an inhalation hazard. INGESTION: Not a probable route of exposure. LONG TERM/DELAYED EFFECTS: None Known. IDENTIFICATION (continued) Note: MECHETEC® Delrin and MECHATEC® Delrin BK stock shapes melt and become unusable for their intended purpose at temperature above 175 C (350 °F). If heated to temperatures over 230 C (446 °F), the polymer releases formaldehyde. Formaldehyde may cause skin, eye, and respiratory irritation and allergic reactions. MEDICAL RESTRICTIONS: There are no known human health effects aggravated by exposure to this product. CHRONIC/CARCINOGENICITY: Chronic inhalation studies in animals have shown that formaldehyde causes nasal cancer in rats. The international agency for research on cancer has classified formaldehyde as a carcinogen in group 2a, and the national toxicology program included formaldehyde in its annual report on carcinogens. CARCINOGEN STATUS FOR FORMALDEHYDE NTP: Not tested OSHA: Not regulated IARC: 2A ACGIH: A2
Medical Conditions Generally Aggravated by Exposure
None Known.
Potential chronic health
There are no known effects from exposure to MECHETEC® Delrin or MECHETEC® Delrin BK polymer itself. Significant skin permeation and systemic toxicity after contact appears unlikely. There are inconclusive or unverified reports of human sensitization.
