|
Surface Friction (PTFE) |
Static/Dynamic Coefficient: 0.04 - 0.08 |
Extremely low friction: Facilitates non-destructive demolding and core extraction of ultra-long polymer catheters. |
|
Thermal Resistance |
Stable under curing zones up to 500°F (260°C) |
Excellent thermal stability: withstands the laser melting and welding temperatures of most polymer heat shrink tubing. |
Applications & Processing Uses
Catheter Reflow & Lamination Fixtures
Acts as the inner lumen structural support matrix during heat-shrink reflow of Pebax, Nylon, Polyimide, and PTFE-lined catheter shafts.
Thermal Shape-Setting Mandrels
Used as specialized pre-shaped tooling to map multi-axis 3D distal curves onto neurovascular, coronary, and steerable structural heart sub-assemblies under heating cycles.
Thermal Laser Welding Cores
Prevents inner diameter collapsing during thermal localized balloon-to-shaft or tip-to-shaft laser bonding processes.
Multi-Lumen Profile Shaping
Custom profile mandrel units enable the exact extrusion alignment of steerable pull-wire lumens and complex non-round channels.
