Teflon® Coated Mandrels Help Assure Catheter I.D. Quality

Teflon® coated stainless steel or nitinol anti-stick forming mandrels that can be supplied cut-to-length for fuse welding and tipping operations are available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics’ PTFE Natural® Extrusion Mandrels for producing small diameter catheter tubing allow over 25% elongation without flaking and failure.  Featuring a 0.5 dynamic coefficient of friction, this anti-stick extrusion, forming and tipping mandrel provides a smooth, slippery surface to permit faster production and help assure optimum catheter tubing I.D. quality.

Capable of withstanding up to 315°C (600°F) service and chemically inert, Applied Plastics’ PTFE Natural® Extrusion Mandrels can be supplied precut in 0.010” to 0.070” dia. sizes with ±.0003” tolerance, depending upon size. Grit-blasted using a proprietary process before applying the release coating assures the coating will not flake or crack, claims the firm.

Applied Plastics’ PTFE Natural® Extrusion Mandrels are priced according to size and quantity.  Samples and quotations are available upon request.

Superior medical devices require superior coatings.

Our proprietary PTFE Natural® coated mandrels offer unmatched benefits.


Low Coefficient of Friction

PTFE Natural® coatings provide a coefficient of friction generally in the range of 0.05 to 0.20, depending on the load and sliding speed.



PTFE Natural® coatings can operate continuously at temperatures up to 550°F and can be used for intermittent service up to 600°F with adequate ventilation.



Non-Stick Very few solid substances will permanently adhere to a PTFE Natural® coating. While tacky materials may show some adhesion, almost all substances release easily.



Chemical environments usually do not affect a PTFE Natural® coating. Only molten alkali metals and highly reactive fluorinating agents are known to affect this coating.



The proprietary PTFE Natural™ coating process enhances the substrate bonding surface to provide optimum lubricity without flaking or cracking.



Since PTFE Natural® finishes are both hydrophobic and oleophobic, cleanup is easier and more thorough.
