What is PTFE and why is it a superior hose core material?
PTFE (Polytetrafluoroethylene) is a high-performance fluoroplastic with high crystallinity
and high molecular weight. Discovered in 1938 by DuPont chemist, Dr. Roy J. Plunkett.
PTFE is more commonly known as Teflon®, the DuPont trade name for PTFE. Parflex
PTFE hose provides fluid conveyance solutions for a wide array of markets and
applications because of the unique properties of PTFE:
Chemical Resistance
– inert to virtually all chemicals
Extreme Temperature Ranges
– 65F to 500F
Low friction
– Minimizes pressure drop and deposits on hose.
Non-Stick
- Easier to clean
Flexible
– convoluted designs have excellent bend radius properties
Resists Moisture
Unlimited Shelf Life
