Downstream process integration

• Material is precision-extruded in cleanroom environments. Tubing undergoes surface finishing and cut-to-length prior to overmolding or thermal bonding with connectors, and subsequent gamma or EtO sterilization.

Final product types

• Diagnostic and infusion catheters
• Balloon angioplasty tubing
• Surgical suction devices
• Flexible endoscopic components

4. Fiber Optic Cable Jacketing

Telecommunications and data infrastructure companies select this nylon to provide protective outer jackets for fiber optic and copper hybrid cables used in both underground and aerial installations.
