ToughFlex™ Extruded 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.

jMedtech is a pioneer in ultra-thin walled medical liner production and one of the first in the world to master both the free extrusion and extrusion over-the-wire liner with mandrel technologies.

Product Introduction

The utilization of the extrusion process facilitates the relaxation of grains within the PTFE matrix, resulting in the formation of axial or extrusion-oriented fibers that enhance strength and rigidity. jMedCath's extruded inner liner achieves an ultrathin wall thickness through innovative design, ensuring optimal strength, flexibility, and traceability. These features empower medical device engineers to delve into advanced designs for catheters and intravascular delivery systems.


Customized Features

The MatrixLiner® Free Extruded Liner offers customizable options, including ToughFlex™ (TF) for high yield strength and ElastiFlex™ (EF)  for high elasticity, providing enhanced flexibility to meet specific application needs.

Product Advantages
  • Ultra-Thin Wall Thickness
    The MatrixLiner® PTFE liner boasts an ultra-thin wall thickness of up to 0.0005 inches (approximately 12 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
    MatrixLiner® PTFE liners undergo rigorous testing to ensure precision and quality. Stringent inspections and tests control the tolerance of the inner diameter within ±0.0005 inches and the wall thickness within ±0.00025 inches.
  • Production Consistency
    MatrixLiner® production follows a consistent process, including extrusion, cutting, winding, and other steps. 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.
  • Excellent Tensile Strength
    Demonstrating superior tensile strength compared to liners from other industry players.
  • After-Sales Service
    Impeccable after-sales service guarantees a worry-free purchase.
  • Support for Custom Sizes
    MatrixLiner® PTFE liners can be customized according to customer requirements, ensuring a precise fit for liners and medical device products. This aims to enhance product reliability and operability, leading to improved performance and results.
  • Short Lead Time
    jMedCath 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.
