Nylon 12 Tubing for Medical Applications
Nylon is a thermoplastic material made of repeating units linked by amide bonds; it is frequently referred to as a polyamide (PA). Nylon was the first commercially successful synthetic polymer, and nylon 12 tubing has proven especially useful for medical applications.
Unique Properties for Medical Tubing Use
Nylon extrusion tubing is ideal for use as medical tubing because it is lightweight, corrosion and abrasion resistant, and can withstand repeated stress over long periods. Polyamide tubing also exhibits excellent resistance to high heat and pressure. Nylon resins can be extruded in thin sections, and are common materials used in catheter shafts due to high stiffness. Nylon 12 tubing is thermally bondable with other polymers used in catheter constructions.
Nylon is also well suited as a balloon material due to its high pressure holding capacity in thin walled sections. Nylon extrusion is ideal for balloon applications which require more compliance than PET balloons offer. Nylon absorbs water, so caution should be used when designing catheters requiring high precision tolerances and dimensional stability at various levels of atmospheric moisture content.
The nylon 12 tubing family includes many variations that are ideal for medical applications, including:
- Rilsan® Aesno Med
Typical medical applications for nylon extrusion materials include catheter shafts and balloon tubing.
