Downstream process integration

• Fed into high-cavitation injection molding equipment, with direct color or additive masterbatch letdown in processing hoppers prior to cavity filling, cooling, and demolding cycles.

Final product types

• Insulin pump casings
• Disposable injector bodies
• Diagnostic test cartridge housings
• Handheld medical device enclosures

3. Flexible Medical Tubing for Drug Delivery Systems

Medical tubing suppliers for drug delivery rely on the polymer's flexibility, biocompatibility, and consistent pressure resistance to extrude multilayer tubing capable of safely transporting a wide variety of parenteral medications. The low leachables profile supports stringent extractables studies mandated in regulatory filings, while smooth inner bores ensure controlled drug delivery rates and reduce likelihood of occlusion during intravenous infusions.

Industry compliance standards

• USP <661.1> Plastic Materials of Construction
• ISO 80369-7: Small-Bore Connectors for Liquids and Gases
• ISO 10993-18: Chemical Characterization of Medical Device Materials

Typical usage ratio

• 85–100% loading in single-polymer tubing; for multilayer constructions, forms inner or outer layer at 30–70% by weight, adjusted based on required drug contact and mechanical layer properties.

Downstream process integration

• Installed in continuous extrusion lines with on-line dimensional (OD/ID) QA, followed by cutting, bonding to connectors, and final ethylene oxide or gamma sterilization steps.

Final product types

• Infusion set tubing
• Peristaltic pump tubing
• Elastomeric pump delivery lines
• Transfer tubing for pharmacy compounding sets

4. Balloon Angioplasty Catheter Balloons

Balloon catheter manufacturers turn to this grade for precision blow-molding of angioplasty balloons requiring excellent burst pressure, compliance, and uniform wall thickness across large lot runs. Its controlled crystallinity and melt consistency help downstream processors achieve critical tolerance control, which is essential for safe, reliable expansion and navigation in coronary or peripheral vasculature.

Industry compliance standards

• ISO 10555-4: Sterile Intravascular Catheters—Balloon Dilatation Catheters

Final product types

• Coronary angioplasty balloons
• Peripheral dilatation balloons
• Stent delivery balloon systems
• Pediatric and specialty dilation balloons

5. Diagnostic Sampling Device Components

Diagnostic device manufacturers prefer this material for components requiring accurate molding of microfluidic channels, sampling ports, and connectors due to its resistance to common clinical chemicals, reliable sterilization compatibility, and capacity to retain mechanical stability during transport and processing. Lot traceability and batch consistency are crucial for high-throughput diagnostic systems where single-use part performance influences overall system accuracy in clinical settings.
