Product Description
We provide comprehensive OEM and contract manufacturing services for PI Tubing (Polyimide Tubing), designed for high-performance catheter shafts requiring ultra-thin walls, exceptional pushability, and superior torque transmission. Our engineering and manufacturing platforms support full-cycle execution from precision dip-coating/extrusion and micro-dimension control to specialized surface modifications, tailored to client specifications.
Features
Ultra-Thin Wall Design: Exceptional micro-wall thickness maximizing internal lumen diameter while maintaining a low outer profile for distal catheter navigation.
Superior Mechanical Strength: High tensile strength and stiffness providing excellent pushability and column support for challenging vascular access.
Exceptional Torque Transmission: High torsional rigidity ensuring precise 1:1 rotation transfer from proximal handle to distal tip.
Thermal & Chemical Stability: High resistance to extreme temperatures and aggressive chemical environments, ensuring reliable clinical performance.
Custom Dimensions: Precise control over inner diameter (ID), outer diameter (OD), and tight tolerance requirements for advanced catheter designs.
