New Product: Radio opaque polymers

A Series of tungsten-filled thermoplastic polyurethanes (TPUs), polyamids (PA), and olefins are radio opaque, making them candidates for medical devices.

Compared to competitive materials, the new grades reportedly mold with smoother surfaces, are easier to injection mold or extrude, resist solvents, and have a high specific gravity. They come in Shore hardness ranges of 75A to 75D and can be ordered in quantities ranging from 25 to 500,000 lb.
