Proprietary Technology

At Applied Plastics, our proprietary technology lets us coat fine wire with a thin, smooth coating of PTFE Natural™ Fluoropolymer to achieve optimum release or slip properties. Our specialty application for this technology is coating stainless steel or nitinol forming mandrels featuring a uniform, precise, non-flaking finish. These mandrels provide a smooth, slippery surface that is chemically inert and withstands up to 288°C operating temperatures. We also apply this superior technology to hypo-tubing.

Applied Plastics coats fine wire with PTFE Natural Fluoropolymer to create forming mandrels that increase the output of small-diameter tubing, formed rubber bladders, and similar products.

Key Features

• Anti-stick
• Non-flaking

PTFE Natural™ Fluoropolymer Mandrels

Stainless steel or nitinol forming mandrels feature a uniform PTFE Natural™ Fluoropolymer coating to achieve a 0.05 coefficient of friction, enabling manufacturers to increase the output of extruded small-diameter tubing, formed rubber bladders, and similar products. Providing a superior bond, the wire is grit-blasted before precisely applying the release coatings in thickness from 0.00127mm to 0.020mm onto stainless steel or nitinol wire from 0.127mm to 1.52mm dia. Forming mandrels are tested in accordance with ASTM-1894.

PTFE Fluoropolymer Coated Hypotubes

Our coating specialists can apply this coating to all variations of stainless steel and nitinol hypotube including spiral, skived, flared, crimped, ground, and slotted types.  We will even source the hypodermic tubing and maintain an inventory and release schedule.

In addition to the hypotubing, as stated above, Applied Plastics specializes in applying this coating onto stainless steel and nitinol forming mandrels which feature a uniform and precise, non-flaking finish.  PTFE Fluoropolymer coatings achieve a 0.05 coefficient of friction, enabling manufactures to increase the output of plastic welding and tipping systems for catheter production.  We have an extensive inventory of medical-grade wire and PTFE coated mandrels for fast delivery.
