Medical Extrusion Mandrel Wire Speeds Small Diameter Tubing Production

A new mandrel wire for extruding catheter tubing and other applications requiring a smooth, biocompatible mandrel which has a low coefficient of friction is being introduced by Applied Plastics Co., Inc. of Norwood, MA.

Applied Plastics’ Medical Extrusion Mandrel is a ptfe coated silver plated copper with a PTFE Natural coating that allows over 25% elongation without flaking and failure for the purpose of extruding precise small diameter medical tubing.  Featuring a 0.05 dynamic coefficient of friction, this anti-stick extrusion mandrel provides a smooth, slippery surface to permit faster production.

Developed to assure optimum tubing I.D. quality, Applied Plastics’ Medical Extrusion Mandrel is available in .010” to .080” dia. sizes with ±.0003” tolerance, depending upon size.  Supplied in continuous lengths on spools, it is chemically inert and can withstand up to 315°C (600°F) service.

Applied Plastics’ Medical Extrusion Mandrel is priced according to size and quantity.  Samples and price 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.
