Kink Resistant Tubing
Kink resistant tubing is used in various applications where it is critical that lumens remain patent. Duke Extrusion’s kink resistant catheters are constructed from flexible polymeric materials that are reinforced with metallic or polymeric filaments or coil.
Kink Resistant Extrusion Design Recommendations
Reinforcing coil/ filament is available in numerous diameters and flat ribbon configurations that provide customizable pic counts (PPI) and tubing wall thicknesses. These unique specifications provide the ability to obtain the ideal flexibility and kink resistance your application requires. We can also provide design recommendations for other unique specifications, including:
- Wire & filament diameters
- Ribbon configurations
- Wall thicknesses
- Material selection
- Sterilization compatibility
- And other factors
Additionally, there are three key metrics to specify when designing a kink resistant catheter, these include:
- Required bend radius
- Column strength needed to avoid buckling under axial load
- Crush resistance required for potential lateral loads
Operating temperatures should also be considered, as high or low temperatures can affect a tube’s kink resistance.
Kink Resistant Catheter Design Challenges
The proper design of a kink resistant extrusion often presents unique challenges that require an optimized combination of wall thickness and kink resistance. Duke Extrusion has the experience and the expertise to recommend customized design options for the development of kink resistant tubing to meet your flexible catheter requirements.
