Multilayer tubing

Product catalog summary
Overview: The document discusses the specifications and advantages of a multi-layer tube designed for high-pressure applications, such as balloon catheters. The tube is manufactured using a co-extrusion process, ensuring high concentricity and precision.
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:
  • The tube maintains a high concentricity of over 90%, crucial for consistent high-pressure handling.
  • Asahi tubes have a controlled concentricity with an average of 97.3% and a standard deviation of 1.7%.
  • General tubes have an uncontrolled concentricity with an average of 94.3% and a standard deviation of 2.6%.
Conclusion: The multi-layer tube is ideal for applications requiring precise and consistent high-pressure performance, with superior concentricity compared to general tubes.

Multilayer tubing-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)
