PTFE, most widely known by DuPont's trade name of Teflon®, was discovered in 1938 by Roy J. Plunkett while working at DuPont’s laboratories.  Teflon® was found to be heat resistant and chemically inert and to have very low surface friction.  In virgin grade, Teflon® has a temperature range from -450F to +500F.  In electrical applications, Teflon® exhibits excellent electrical stability over a wide range of frequency and environmental conditions.  Teflon® is unaffected by outdoor weathering, it is non-flammable and non-adhesive.

PTFE machining or Teflon® machining has a variety of uses as manifolds, insulators, guides, slide blocks, cathode and anode end blocks, arc shields, beads, seals, washers, valve seats and can be found in many industries.
 
East Coast Precision Manufacturing has experience working with Teflon® machining and PTFE machining to machine many types of Teflon® parts and PTFE parts such as:

• Teflon® bushings

• Teflon® insulators
