PTFE Beading

PTFE beading is a small diameter rod manufactured from a chemically resistant PTFE (polytetrafluoroethylene) resin. Self-lubricating and with a low coefficient of friction, PTFE beading is ideal as a pull cord, O-ring seal, bearing, and as both a spacer and filler for cable bundles and harnesses. High-temperature PTFE beading can be found in aerospace, chemical processing, semiconductor, and automotive applications.

PTFE beading or monofilament is manufactured as a paste product which allows for long lengths when compared to granular rods. However, it can’t be machined. Teflon beading can also be manufactured from melt products, such as FEP and PFA, which will work as bonding agent.
