PTFE Teflon
yarn coated with graphite and lubricated with an inert
high temperature lubricant.
Advantages :
• Less gland adjustment, easy break-in & even
compression in all rings.
• Six times better heat conduction as against pure
P.T.F.E packings at comparatively high speeds.
• Significantly low thermal expansion thus resisting
'over expansion' extrusion under service.
