History
PTFE is a synthetic fluoropolymer that was accidentally discovered by Roy Plunkett of DuPont in 1938. In 1941, the polymer was trademarked under the name Teflon™. Fibers have been produced from the PTFE polymer since the 1950’s.
Composition
PTFE fibers are typically produced using two different methods. The first method is matrix-spun, in which the fiber produced is round and brown in color. The second method, referred to as paste-extrusion, produces a flat white finished product. Typically, fibers produced using paste-extrusion have higher tenacity.
