MATERIALS:Putnam Plastics announces the development of an advanced technology for producing thin walled, large diameter, low durometer urethane extrusions. After extensive development, Putnam Plastics implemented a proprietary combination of custom equipment and advanced processing conditions to address all of the historical challenges to the fabrication of this type of tubing. Improved process stability results in a larger design envelope for device engineers, and improved material handling techniques reduce costs by increasing yields and product quality. This new capability is widely applicable across a broad range of custom extrusion designs with the greatest impact in OD’s greater than 0.500 inch and wall thicknesses of less than 0.015 inch in urethane durometers lower than 90A. As with all of Putnam Plastics’ custom fabrication technologies, this new capability can be applied cross functionally and integrated into designs that include features such as coextrusion, multi-lumen, wire reinforcement, etc. The end result is a wider envelope of possibility for device design engineers to meet the functional needs of clinicians without compromise.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
