Lubricious / Low Friction Tubing Solutions

Lubricious surfaces are a critical feature of every minimally invasive device. Low friction lumens allow devices to readily access tortuous anatomy and tight spaces with a minimum of force. 

Spectrum Plastics Group has decades of experience in manufacturing minimally devices and offers a range of lubricious catheter materials that are fast, reliable, and low friction.

  • HDPE tri-layer extrusion
  • HDPE tri layer with reinforcement
  • Film- cast PTFE liner w/ braid and Pebax® outer
  • Pebax® with EverGlide®
  • Pebax® with ProPell™  

Co-, Tri-, and Multilayer Extrusion

With decades of experience, our extrusion capabilities include coextruded and tri-layer extruded tubing, aligning materials with different performance properties into a single solution.

Core Mandrel (Solid Rod Extrusion)

Core mandrel by SPG

Used as a manufacturing aid for braid- or coil-reinforced catheter tubing, our core mandrels feature extremely tight tolerances to maintain consistent diameter and roundness for catheter manufacturing, as well as a smooth surface for easy removal.

Material Options

  • Premium plain acetal mandrel
  • Premium acetal blend with silicone surface mandrel
  • Acetal or silicone acetal (small OD) with stainless steel wire reinforcing
  • Economy version
