DAYVILLE, Conn.—Earlier this year, Putnam Plastics Corporation expanded its product portfolio to include RilSlix™ coated mandrels and wires. The new products are reported to incorporate a unique surface chemistry that has been optimized for use as a processing aid in catheter manufacturing, the company said in a press release. They employ a range of fluoropolymer coatings, including the proprietary RilSlix coating. All coatings are compatible with discrete, tapered and continuous wire.

The RilSlix compounds have been designed with PFOA-free, REACH-compliant materials and are said to exhibit up to five times stronger adhesion of the coating to the mandrel than industry standards. RilSlix technology offers excellent durability, which enables wires and mandrels to be used repeatedly without flaking, according to Putnam Plastics.

The combination of performance, wear-resistance, and longevity is said to make RilSlix coated mandrels a cost-effective option, superior to standard fluoropolymer coated wires and mandrels.

“As a catheter engineer, my team regularly utilizes coated mandrels in the manufacturing of complex catheters,” said Robert St. John, senior catheter engineer at Putnam Plastics, in a statement. “These new mandrels, coated from RilSlix compounds, are ideal for multi-lumen catheters, reflow processes, or continuous processes where mandrels are required, as they are easily released and can be used over and over again without flaking.”

Discrete mandrel and continuous wire coating is compatible with a variety of metals,  including  stainless steel, silver plated copper, and Nitinol, in diameters ranging from 0.010 inch to over 0.500 inch (0.254mm to 12.7mm), the company said. Putnam can also accommodate discrete lengths up to 13feet (4m).

Putnam Plastics said that its engineers are available to assist in material selection and optimization to ensure that the polymer coating that is ultimately selected is best suited to meet specific product performance requirements. Samples are available in formats that will allow customers to evaluate bond strength, frictional properties, and durability.

The company offers in-house testing for all adhesion and coating processes. By providing both manufacturing and testing under one roof, customers benefit from a reduction in lead time and access to product design that is customer specific.

Putnam Plastics Corporation (www.putnamplastics.com), a pioneer in advanced extrusion for minimally invasive medical devices, has more than three decades of experience in medical tubing, with a focus on small diameters used for life-saving vascular catheters and minimally invasive medical devices. Putnam offers a wide range of tubing technologies and tube finishing operations and frequently combines the technologies “to create components at the forefront of today’s most sophisticated medical devices,” the company said.
