PTFE coated forming mandrels feature uniform, non-flaking finish

Durable, PTFE coated precise forming mandrels for manufacturing small diameter parts including extruded tubing and formed rubber bladders are available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

APC PTFE Natural™ Fluoropolymer Mandrels feature a uniform, non-flaking PTFE coating on stainless steel or nitinol wire. Providing an anti-stick surface that exhibits a 0.05 coefficient of friction per ASTM-1894, these mandrels withstand 550°F continuous temperatures with excursions up to 700°F.

Unlike conventional green mandrels that typically flake, PTFE Natural™ Fluoropolymer Mandrels are grit-blasted to enhance the bonding surface. Then the PTFE coating is precisely applied from 0.00005” to 0.0008” thick onto wire from 0.005” to 0.070” dia. with a ±0.0001” final dia. tolerance.

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

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.
