• Compressed air distribution hoses
• Protective sheathings for wiring harnesses

3. Medical Device Tubing (Non-Implantable)

Medical consumables manufacturers specify this grade of polyamide 12 for infusion, catheter, and peristaltic pump tubing where kink resistance, chemical inertness, and biocompatibility are essential. After compounding, it exhibits a balance of flexibility and strength needed for repeated handling and sterilization. Medical OEMs benefit from its consistent dimensions and controlled extractables under regulatory scrutiny, making it suitable for direct patient contact or critical fluid pathways, provided it is not used in implants.

Final product types

• Disposable infusion sets
• Peristaltic pump tubes
• Medical sampling lines
• Oxygen and anesthesia transfer tubing

4. Industrial Cable Sheathing & Fiber Optic Jacketing

Specialty cable and fiber-optic manufacturers choose this conditioned polyamide 12 to deliver resistance to abrasion, oils, and environmental exposure in demanding electrical and telecommunication installations. Its low dielectric constant, tight dimensional tolerances, and stress crack resistance protect copper wiring and optical fibers throughout energy and data transmission networks, including underground and outdoor applications where traditional sheathing fails under mechanical or chemical attack.
