Catheter Forming Mandrels Durable, Non-flaking and PFOA-Free


A line of Teflon® coated mandrels that will not flake or crack during catheter fuse welding and tipping operations are free of PFOA (Perfluorooctanic acid) is available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics’ PTFE Natural® Grey Forming Mandrels feature a proprietary surface preparation process and a PFOA-free coating that will not flake, peel, or crack. Providing a 0.5 dynamic coefficient of friction, these highly durable mandrels prevent the tubing from sticking, block shrinking, and allow over 25% elongation to simplify catheter removal.

Ideally suited for catheter manufacturing, small diameter extruded tubing, and formed balloons, Applied Plastics’ PTFE Natural® Grey Forming Mandrels are chemically inert and can operate at 600°F continuous. Offered in stain-less steel or nitinol, they can be supplied precut in 0.005” to 0.50” dia. sizes with ±.0003” tolerance, depending upon size.

Applied Plastics’ PTFE Natural® Grey Forming 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.
