Multi layer tube

Product catalog summary
Overview
The document describes a multi-layer tube designed for high-pressure applications, such as balloon catheters. The tube's high concentricity (over 90%) ensures consistent and effective pressure handling.

Specifications
  • Wall Thickness: 0.0020” - 0.0047” (0.05 - 0.12mm)
  • Outer Diameter: 0.016” - 0.039” (0.4 - 1.0mm)
  • OD Tolerance: ± 0.0008” (±20μm)
  • Material: General purpose resin (HDPE, PA, PA Elastomer, TPU, etc.)
  • Number of Layers: 2 or 3 layers, with different polymers possible
  • Supplied Length: Cut length up to 1500mm
  • Available Layer Ratio: Inner 10 - 20%, Middle 10 - 80%, Outer 10 - 70%

Performance Comparison
  • Asahi Tubes: Concentricity controlled over 90%, with a standard deviation of 1.7% and an average of 97.3%.
  • General Tubes: Concentricity uncontrolled, with a standard deviation of 2.6% and an average of 94.3%.

Conclusion
The multi-layer tube's design and material composition make it ideal for applications requiring precise pressure management, such as in medical devices like balloon catheters.

Multi layer tube-1

Datasheet : Extrusion : Multilayer Multi layer tube Cross section Our Multi layer tube, with high concentricity (more than 90%), enables the catheter to handle high pressures consistently and effectively. With the co-extrusion process, unlike welded tubing, our seamless precision tubing meet critical design tolerance. Ideal for the application requires handling high pressure evenly, such as a balloon catheter, for ensuring a tight fit between balloon and blood vessel. Specifications Wall thickness : Outer diameter : General purpose resin (HDPE, PA, PA Elastomer, TPU etc.) 2 or 3 layers, all different polymers possible Supplied with : Available layer ratio : Asahi - Controlled over 90% - STD-1.7% - Average: 97.3% General - Uncontrolled Concentricity of 3 layer tube, Asahi vs General (internal investigation)
