Composites
Particle composites are used to produce radiopacity, lubricity or significantly improve thermal conductivity. At MinVasive Components, we have the expertise to deliver the composites you need, such as radiopaque polyimide tubing as well as boron nitride polyimide with more thermal conductivity than standard polyimide properties.
Radiopaque Polyimide Tubing
At MinVasive Components, our tungsten-loaded polyimide-tubing product is inherently radiopaque for visibility under X-ray and fluoroscopy.
Benefits
- Cost effective alternative to metallic tubing
- Radiopaque image with polymeric properties
