Strip and Recoat Service Renews Fuse Welding and Tipping Mandrels


A new service for fuse welding and tipping mandrels that strips worn Paryleneand Tefon(R) coatings and applies PTFE NaturalTM coatings like new is being introduced by Applied Plastics Co., Inc. of Norwood, Massachusetts.

Applied Plastics Forming Mandrel Strip and Recoat Service strips the old Parylene(R) and Teflon(R) coatings from forming mandrels and applied a new PTFE NaturalTM Coating.  Featuring a smooth, anti-stick surface that withstands heat up to 300o C continuous, with excursions to 371o C, PTFE NaturalTM coated forming mandrels provide a 0.05 coefficient of friction per ASTM-1894 to simplify catheter removal in fuse welding and tipping operations.

Ideal for larger diameter mandrels 0.020″ and up, Applied Plastics Forming Mandrel Strip and Recoat Service lets users recondition rather than discard worn mandrels which saves delivery time and eliminates grinding; especially with complex configurations.  PTFE Natural mandrels are coated using a proprietary process which enhances their bonding surface and prevents flaking and cracking.

Applied Plastics Forming Mandrel Strip and Recoat Service is priced according to coating requirements and quantity.  Quotations are provided 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.
