Choose Your Path (Go to the Right Subpage)
Start with the dominant application form. For multi-constraint projects (e.g., soft feel + long-term stability, transparency + welding + process stability), start from the closest path and request a combined shortlist via advanced functional tuning.
Medical Catheter TPU
TPU materials positioned for catheter structures where flexibility, surface stability and long-term performance consistency are central to selection.
Surface Stability
Consistency
Precision Extrusion
- Stable mechanical behavior under bending and routing
- Controlled surface and feel for reliable device handling
- Manufacturing repeatability with disciplined processing
Medical Tubing TPU
TPU systems for medical tubing where wall-thickness consistency, appearance stability and stable extrusion windows reduce trial and scale-up risk.
Wall Consistency
Appearance
Process Window
- Repeatable tubing geometry across long runs
- Balanced softness and toughness for handling and routing
- Stable output with controlled heat and shear
Medical TPU Wound-Care Film
Film-focused TPU materials for wound-care systems where skin comfort, smooth surface and stable film forming are key.
Film Forming
Surface Smoothness
Thickness Control
- Skin-contact comfort with stable film feel
- Controlled surface for consistent appearance
- Film processing compatibility (project-dependent)
Medical Bag TPU
TPU materials for medical bags and flexible containers where sealing reliability, sheet performance and long-run stability drive selection.
Sheet / Film
Durability
Clarity Options
- Sealing integrity and stable weld behavior
- Stable film/sheet performance for forming and handling
- Repeatable manufacturing for consistent bag quality
Typical Data (Reference Only)

Note: Data for reference only. Device performance depends on formulation, processing window, finished-part geometry, and verification plan (project-dependent).
Customization Options (Project-Focused)
Beyond standard grade families, medical TPU systems can be tuned around real project risks such as process drift, surface feel, sealing reliability and long-term performance. Typical customization directions include:
Consistency & Repeatability
- Lot-to-lot stability strategy for scale-up projects
- Wider processing window tuning (reduce drift sensitivity)
- Appearance stability over long production runs
Surface & Feel
- Surface smoothness and tactile feel tuning (project-dependent)
- Anti-block direction for film and sheet handling
- Surface stability under processing heat history
Low Odor / Low VOC Direction
- Formulation direction for reduced odor/VOC contribution
- Processing discipline guidance to avoid degradation odor
- Appearance and smell stability after aging (project-dependent)
Extractables / Migration Direction
- Lower extractables direction by formulation strategy
- Package choices aligned to contact type (project-dependent)
- Verification guidance aligned to your internal protocol
Sterilization Considerations
- Property retention direction under sterilization routes (project-dependent)
- Color/clarity stability direction after sterilization exposure
- Balance between softness and retention margin
Film / Sheet & Sealing
- Film forming stability and thickness control direction
- Welding / sealing behavior tuning for bag structures
- Balance between seal strength and handling toughness
Note: Customization scope depends on device form, contact type, process route and verification plan. For multi-constraint projects, we recommend starting from the closest application page and requesting an advanced functional shortlist.
Request Samples / TDS
Share your device form, processing route, and key constraints. We will recommend a shortlist and provide TDS/SDS for trials.
