Custom Medical Grade Pebax Tubing (Shore 25D – 74D
Pebax Tubing ist ein hochleistungsfähiges Polyether-Blockamid, das es Entwicklern medizinischer Geräte ermöglicht, die Grenzen in Bezug auf Festigkeit und Flexibilität zu verschieben。 Pebax-Material verfügt aufgrund des gleichmäßigen Schmelzflusses über eine hervorragende Verarbeitbarkeit, ein enger Verarbeitungstemperaturbereich über ein breites Modulspektrum, und gleichmäßige Molekulargewichtsverteilung (minimale Gele), all of which contribute to the ability of pebax foam resin to be extruded in dünne Wand Abschnitte nach unten Pebax-Schlauch medizinisch ,PEBAX 7233 PEBAX5533 AOKRAY benutzerdefinierte pebax sa01 sp01 2533/3533/4033/4533/5533/6333/7233 medical grade with Barium .Pebax tubing medical size as ID0.01″-0.472″ ,Wall 0.0019″-0.118″ (Holen Sie sich PEBAX.pdf ) ,Aokeray also custom Pebax heat shrink tubing Aokeray is a premier OEM manufacturer specializing in medical-grade Pebax tubing custom extrusions for advanced interventional catheters and delivery systems. We offer a comprehensive durometer range from ultra-soft 25D/35D for atraumatic tips to rigid 72D/74D for maximum torque transmission. Our precision multi-lumen and co-extruded Pebax shafts feature micro-bore profiles, ultra thin walls, and custom radiopaque fillers (BaSO4 Or BI2O3. Produced in ISO Class 7 cleanrooms, we ensure medical devices achieve optimal flexibility, Verfolgbarkeit, and biocompatibility

Why is Pebax preferred over standard Nylon or Polyurethane in catheter manufacturing?
Pebax (Polyether Block Amide) bridges the gap between the mechanical properties of rubbers and thermoplastics. It offers a broader range of hardness (25D to 74D), superior kink resistance, outstanding elastic recovery, and low low-temperature brittleness, making it the industry standard for torque-transmitting catheter shafts.
Can you customize Pebax tubing with varying hardness along a single tube length?
Ja. We manufacture customized tapered and bump tubing, as well as variable-stiffness extrusions. This allows the catheter shaft to seamlessly transition from a stiff proximal zone (e.g., 72D) to a highly flexible distal tracking zone (e.g., 35D) without requiring manual thermal welding
What radiopaque fillers do you add to Pebax, and what are the standard concentrations?
We standardly compound custom Pebax with Barium Sulfate BiSO4 oder Bismuth TrioxideBi2O3, typically at concentrations of 20% oder 30% by weight. We can also source custom loading percentages based on your specific visual density and wall thickness requirements.
Does your Pebax tubing support thermal bonding with other fluoropolymers?
Pebax bonds exceptionally well with other polyamides and can be easily reflowed over chemically etched PTFE liners or FEP heat shrink liners using standard FEP heat shrink reflow processes
Is your Pebax tubing bio-compatible and regulatory compliant?
Ja, all our custom Pebax extrusions utilize virgin resins that are fully compliant with USP-Klasse VI Und ISO 10993 bio-compatibility standards, ensuring safe long-term and short-term interventional human body use.

Information needed for a medical Pebax tubing review
Provide the drawing or specify the Pebax grade or hardness requirement, nominal ID, AUS, wall thickness, Maßtoleranzen, Schnittlänge oder Spulenformat, color or radiopaque requirement, Montageprozess, sterilization method, Prototypenmenge, annual demand and requested quality documents.
Pebax grade and hardness affect flexibility, recovery, kink response and processing, but grade alone does not define finished-component performance. The complete shaft construction, reinforcement, Geometrie, additives, thermal history and device validation must be considered before a material and dimension are confirmed.
