It's great to be number one.

"Having been in business all these years, it’s great to be number one - known as the best - someone that impresses your customers."


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.



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.
