PTFE coated forming mandrels withstand up to 550°f continuous temperatures

High heat-resistant PTFE coated stainless steel or nitinol forming mandrels for manufacturing small diameter extruded tubing and formed rubber bladders are available from Applied Plastics Co., Inc. of Norwood, Massachusetts.

PTFE Natural™ Fluoropolymer Mandrels feature a uniform, non-flaking coating which provides a smooth, anti-stick surface that can withstand 550°F continuous temperatures with excursions to 700°F. Designed to increase the output of extruded small diameter tubing, formed rubber bladders, and similar products, they are made from stainless steel or nitinol wire.

Exhibiting a 0.05 coefficient of friction per ASTM-1894, APC PTFE Natural™ Fluoropolymer Mandrels are manufactured using a proprietary process which involves grit-blasting the wire before applying the release coatings in thicknesses from 0.00127mm to 0.020mm onto stainless steel or nitinol wire from 0.127mm to 1.52mm dia. with ±0.00254mm final dia. tolerances.

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.
