Stevens thermoplastic polyurethanes (TPUs) are for medical and surgical devices. These TPUs do not contain plasticizers and are suitable for high-performance products used in critical "can't fail" medical situations. Stevens Urethane Film, Sheet, and Tubing for Medical Applications brochure includes tables that compare the properties of urethane, such as elongation, tear, and strength, with other flexible materials such as PVC. Information on products using TPUs is also included.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
