Tecoflex® is a family of medical-grade aliphatic polyether polyurethanes. They do not yellow and are available over a wide range of durometers, colors and radiopacifiers, including barium sulfate, bismuth salts and tungsten. The low durometer grades in particular may not be suitable for long-term implant applications because of the potential for stress cracking.
Glossary Of Terms
Organic chemical compounds in which the carbon atoms are linked in open chains, including paraffins, olefins and acetylenes. Aliphatic compounds have lower unsaturation indices than aromatic compounds.
