MorphoLiner™ Casted OTW PTFE Liner
jMedtech provides three main PTFE liner production methods: Free Extrusion, Over-the-Wire (OTW) Extrusion, and Film Casting/Dip Coating. Our experienced engineers select the best technique based on the catheter’s design and application to optimize size, strength, and flexibility.
Product Introduction

The Dip Coating process produces thinner PTFE liners and enhances surface adhesion with a thin thermoplastic outer layer. This process creates isotropic properties by preventing molecular orientation in individual PTFE chains.

Product Advantages
  • Ultra-Thin Wall Thickness
    The MorphoLiner™ Casted OTW PTFE Liner boasts an ultra-thin wall thickness of up to 0.0003 inches (approximately 7.62 microns). This thin-wall structure enhances material softness and transparency, reducing the catheter diameter. The ultra-thin design improves lubricity, minimizing damage and irritation to surrounding tissues during medical instrument insertion and withdrawal.

  • Industry-Leading Tolerance
    MorphoLiner™ Casted OTW PTFE Liner undergoes rigorous testing to ensure precision and quality. Stringent inspections and tests control the tolerance of the inner diameter to within ±0.0003 inches and the wall thickness to within ±0.0001 inches.

  • Production Consistency
    MorphoLiner™ production follows a consistent process. Each stage adheres to the strictest standards to guarantee product uniformity and reliability. This ensures a stable and reliable component for the research, development, and production of medical devices.

  • Quality Assurance
    Manufactured in ISO 13485-compliant cleanrooms, MorphoLiner™ meets medical device biocompatibility standards, supported by advanced equipment and precise measurement tools.

  • After-Sales Service
    Impeccable after-sales service guarantees a worry-free purchase.

  • Support for Custom Sizes
    MorphoLiner™ production follows a consistent process. Each stage adheres to the strictest standards to guarantee product uniformity and reliability. This ensures a stable and reliable component for the research, development, and production of medical devices.

  • Short Lead Time
    jMedtech excels in procurement, production, sales, and other supply chain functions, significantly reducing the delivery cycle. The lead time for standard products is 2 weeks, while regular customized sizes have a lead time of 4-8 weeks.
