Fluoropolymer Forming Mandrels Withstand 700°F Excursions and Won’t Flake

A line of medical-grade forming mandrels which feature a uniform fluoro-polymer coating that will not flake, for manufacturing small diameter parts, is available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

APC PTFE Natural® Fluoropolymer Forming Mandrels are made from stainless steel or nitinol wire and feature a smooth, uniform fluoropolymer coating that will not flake.  Capable of excursions to 700°F and 550°F continuous operation, higher than Parylene coated mandrels, these gray forming mandrels exhibit a 0.05 coefficient of friction per ASTM-1894.

Ideally suited for fuse welding and tipping operations, APC PTFE Natural® Fluoropolymer Forming Mandrels are now available in lengths up to 12 ft.  The wires are stocked in sizes from 0.005” to 0.070” dia. and the proprietary coating is applied from 0.00005” to 0.0008” thick with a ±0.0001” final dia. tolerance. Specials are available on request.

PTFE Natural® Fluoropolymer Forming Mandrels are priced from $1.19 per foot; with delivery from stock.  Free samples and literature 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.
