Teflon® Coated Extrusion Wire Improves Cardiovascular Catheter Manufacturing

A line of medical-grade Teflon® coated extrusion wire and forming mandrels for manufacturing cardio-vascular catheters, balloons, and related devices, where a clean inside diameter is absolutely critical, is available from Applied Plastics Company, Inc. of Norwood, Massachusetts.

Applied Plastics’ Teflon® Coated Extrusion Wire is fabricated using a prop-rietary etching process that eliminates flaking and permits over 25% elonga- tion to keep the catheter’s inside diameter clean.  Supplied spooled or cut to length, this fine extrusion wire features a 0.05 coefficient of friction which prevents sticking and simplifies its removal from the catheter.

Providing a slippery, anti-stick surface, Applied Plastics’ Teflon® Coated Extrusion Wire can be produced using stainless steel, nitinol, platinum and silver plated copper core wire.  Sizes can range from 0.001” to 0.070” dia. with a 0.0001” per side Teflon® coating. Applications include cardiovascular and epidural catheters, formed balloons, and other bio-compatible devices.

Applied Plastics’ Teflon® Coated Extrusion Wire is priced according to core wire, coating thickness, length, and quantity.  Samples, price quotations, 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.
