PTFE coated Mandrels or otherwise known as pull wires or core wires are designed to be reusable or disposable and come in various lengths, diameters, and alloy substrates. They play a crucial role in the buildup and manufacturing of critical polymer based vascular catheters that enter the venous system. This is where utilizing Miller-Stephenson’s 850G-1040 coating offers exceptional anti-stick, multiple release properties as well as repeated strength, durability, and reliability with no flaking or delamination. These robust, abrasion resistant, durable PTFE coatings also offer the ability to utilize sensitive substrate alloys for specially designed critical medical devices or supplies.
