FAQ about PFA Teflon Tubing

Why use PFA Teflon when PTFE & FEP Teflon are so much less expensive?
PFA Teflon tubing is often the resin of choice when additional clarity, flexibility, and a higher continuous service temperature are required.  PFA provides that extra margin of safety or assurance that it will perform in the environment.

PFA tubing is preferred when extended service is required in hostile applications involving chemical, mechanical and thermal stress.

Why was PFA Teflon developed?
PFA Teflon tubing was developed to increase the continuous service temperature of FEP resin to 500-deg F (260-deg C).  PTFE can also handle this temperature; however, the processing method limits the continuous lengths that can be achieved.  Melt processablility allows PFA to be processed in much longer continuous lengths (x5-10) than PTFE.

What are some everyday applications of Teflon?
Virtually every home contain items that use Teflon in some way.  Many frying pans are coated with Teflon to ensure food does not stick. Because of its low friction, Teflon has become invaluable in everyday use.  Even some toilet bowl cleaners now include Teflon to ensure "debris" doesn't stick the toilet bowl.  Plants stems and tree trunks can be sprayed with Teflon to prevent insects from climbing surfaces.

What are some not-so everyday applications of Teflon?
Certain armor piercing bullets are coated with a Teflon spray to permit better penetration.
