OEM China Factory PEBAX Tube+70% Tungsten Disposable PEBAX Modified Medical Tubing for Radiopaque Catheter
Introduce
Materials：PEBAX4533+70%Tungsten
Specification Parameter：2.05*0.075
Advantage：The performance of medical Pebax tubes with 70% tungsten additive will exhibit the following changes:
Significantly enhanced radiopacity**: The high density of tungsten greatly improves X-ray visibility, facilitating precise positioning during medical procedures.
Increased rigidity**: High tungsten content in the polymer matrix elevates tube hardness, potentially reducing flexibility.
Higher density and weight**: Tungsten's density (19.25 g/cm³) drastically exceeds Pebax (≈1.0 g/cm³), causing substantial weight increase.
Altered tensile properties**: Ductility may decrease, while compressive strength could improve, requiring experimental validation.
Note: Excessive tungsten content may impact processability, necessitating a balance between performance and manufacturability.
Application：
Introducer Sheaths and Catheters in Interventional Procedures
Application Description : In cardiovascular, neurovascular, or peripheral vascular interventions, physicians need to insert sheaths or catheters into blood vessels as conduits for devices (such as stents and balloons).
Positioning and Navigation in Minimally Invasive Surgery.
Application Description : In fields requiring precise delivery to the treatment site, such as tumor intervention or pain management (e.g., nerve blocks).
Structural Support and Mapping
Application Description : Can be used to manufacture certain devices requiring built-in radiopacity or as components for mapping catheters.
