polytetrafluoroethylene

(pŏ-lē-tĕ-tră-flŏ-rō-ĕth′ĭ-lēn),

PTFE

A synthetic polymer that has slippery, nonsticking properties. It is used in a variety of products, including vascular grafts used to bypass obstructed blood vessels and grafts used for dialysis access.

polytetrafluoroethylene

a synthetic material commonly used as a nonstick lining in domestic cooking utensils (frypans); abbreviated PTFE; called also Teflon. Overheating produces toxic fumes that cause an acute hemorrhagic pneumonitis and death in small caged birds, which are particularly susceptible. Called also polymer-fume fever, kitchen deaths. See also polytef.
