What Is Pebax Tubing？

Pebax tubing is composed of a blend of thermoplastic elastomers, typically consisting of polyether and polyamide segments. This unique composition imparts Pebax tubing with its distinctive combination of flexibility, durability, and biocompatibility, making it an excellent choice for medical tubing applications.

Benefits of Pebax Tubing

Thin walls: Pebax® can be extruded into very thin tubing (down to 0.001 inches) due to its consistent flow and uniform structure.

Variable flexibility: Multiple layers with different flexibilities (25D to 74D) can be combined in the same tube.

Shape retention: Pebax® has high elastic memory, making it ideal for catheters and other devices that need to endure bending and twisting without breaking.

Consistent performance: Pebax® performs well at body temperature, ensuring catheters and other devices function reliably within the body.

Stable product size: The Balloon Material Tube maintains consistent dimensions, ensuring uniformity and reliability in the final balloon product.

Highly resistant to chemical degradation and offers low friction properties, reducing the risk of tissue irritation or damage during use.

Coaxiality ≥ 95%

This specification denotes the concentricity or alignment of the layers within the tube, ensuring that the balloon material is evenly distributed around the central axis. High coaxiality enhances the performance and reliability of the balloon during inflation and deflation.

Less appearance defects

The Balloon Material Tube exhibits minimal visual imperfections or defects such as air bubbles, wrinkles, or irregularities on the surface, ensuring aesthetic appeal and quality consistency in the final balloon product.

Balloon forming pass rate ≥ 90%

This specification indicates the success rate of the balloon forming process, where at least 90% of the balloon material tubes are successfully transformed into balloons without defects or failures. A high pass rate ensures manufacturing efficiency and reduces waste.

Types of Pebax Tubing

Catheters

Due to its inert nature and ability to produce multi-durometer lengths, PEBAX® is widely accepted as a catheter material of choice. PEBAX® has the ability to be reheated and form multiple components of a continuous length catheter. Since a catheter may require varying hardness along its length, one can use small sections of a hard PEBAX® followed by a soft PEBAX® grade. Additionally, it can easily be extruded into multi-lumen profiles, which is another desirable feature for catheters.

Balloon tubing

There are two main categories of balloon tubing: compliant (low pressure) balloons and high pressure balloons. PEBAX bridges the two categories because it can be easily coextruded with polyamides to have a higher modulus, but it is softer than traditional low pressure balloons. Due to this lower level of softness, it is still able to maintain a relatively higher burst (depending on durometer, wall thickness and nylon grade) and it can be used and then collapsed for ease of extraction during a procedure.

Application of Pebax Tubing

General fluid transfer: Due to the inertness of PEBAX®, it performs very well in cytotoxicity texting and thus is well suited for sensitive blood transfer applications where any disruption of blood cells could have undesirable outcomes. Additionally, it has a slightly higher flexural modulus than many TPEs and performs better in kink resistance testing.

Process of Pebax Tubing

Extrusion
There are numerous crucial processes in the extrusion process for this tubing:

Preparation
To guarantee ideal consistency and avoid moisture-related problems during extrusion, PEBAX pellets are dried.

Melting and mixing
To create a homogeneous consistency, the dry pellets are put into an extruder and melted and well combined.

Shaping
Next, a well-crafted die is used to push the molten PEBAX through. The molten plastic is shaped by this die into the appropriate tube profile, which includes the wall thickness, diameter, and even possibly intricate forms.

Cooling and finishing
After extrusion, the tube is chilled and solidified in a regulated environment. It then goes through finishing procedures including cutting and inspection to make sure it satisfies the requirements.

How to Maintain Pebax Tubing

Gentle cleaning
Use lukewarm water and mild soap for regular cleaning. Steer clear of abrasive cleansers and strong chemicals since they might cause surface damage to the tubing.

Chemical compatibility
Verify that fluids are compatible with PEBAX before handling them. Steer clear of extended exposure to strong chemicals since this might damage the tubing.

Cool and dry storage
Keep your tubing in a cool, dry location when not in use. Steer clear of extreme heat or intense sunshine since they may eventually alter the tubing’s characteristics.

Limitations

Cost: Pebax® may be more expensive than some other plastic materials, which could limit its use in cost-sensitive applications.

Heat resistance: Although Pebax® has good thermal resistance, it may not be as stable at extremely high temperatures as some specialized engineering plastics.

Resistance limitations: While Pebax® is resistant to many chemicals, it may be sensitive to certain solvents or chemicals, limiting its application in specific chemical environments.

Processing conditions: Processing Pebax® may require specific conditions and equipment to ensure the best performance of the material.

Long-term stability: Long-term exposure to certain environmental factors, such as ultraviolet light or certain types of radiation, may cause degradation of Pebax®.

Application limitations: Although Pebax® has a wide range of applications, it may not be suitable for applications requiring extreme mechanical properties or special electrical properties.

Environmental impact: Compared to other biodegradable materials, the environmental impact and sustainability of Pebax® may require further assessment.

How the Medical Tubing Manufacturing Process Works

To start the medical tubing manufacturing process, a polymer must be chosen for your application. Some of the most common polymers used in the medical industry include polycarbonate, polypropylene, and polyethylene — however, there are other options you can discuss with your manufacturing partner.

Once the polymer is chosen, the manufacturing process can begin. Typically, due to the nature of the application of these products, manufacturing will take place in an ISO-certified cleanroom. Cleanrooms are a controlled manufacturing environment that filters out pollutants that may harm the patient or impact the function of the product. By producing medical tubing in a cleanroom, you will ensure that your products are free from harmful debris or pollutants when they leave production.

During the manufacturing process, the chosen plastic is fed into the barrel of the plastic extruder. Here it is melted by heaters and turning screws. Then, the melted plastic is forced through the extrusion die, and as it cools, the polymer takes its permanent shape.
