Durable PTFE-coated catheter-forming mandrels offered by Applied Plastics

PTFE-coated mandrels that offer defect-free performance during catheter welding and tipping operations are available from Applied Plastics Co. (Norwood, MA).

The mandrels undergo a proprietary surface preparation process and feature a PFOA-free coating that will not flake, peel, or crack. Providing a 0.5 dynamic coefficient of friction, these “highly durable” mandrels prevent the tubing from sticking and block shrinking, and allow more than 25% elongation to simplify catheter removal, the company said in its information.

Suited for catheter manufacturing, small-diameter extruded tubing and formed balloons, Applied Plastics’ PTFE-coated mandrels are chemically inert and can operate at 600° continuous. Offered in stainless steel or nitinol, they can be supplied precut in diameters ranging from 0.005 to 0.05 inches with a +/- 0.0003-in. tolerance, depending upon size.
