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 extrusion process in jMedtech’s ToughFlex™ extruded PTFE tubing promotes grain relaxation within the PTFE matrix, creating axial, extrusion-oriented fibers that significantly improve strength and rigidity. This advanced approach allows the custom PTFE extruded tubing to achieve an ultrathin medical thin wall tubing design with outstanding flexibility, durability, and full traceability. As a trusted choice among PTFE liner suppliers, jMedtech delivers precision medical tubing and extruded tubing medical solutions that empower engineers to pursue innovative catheter custom extrusion and next-generation 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 ToughFlex™ PTFE extruded tubing from jMedtech achieves an ultra-thin wall thickness of up to 0.0005 inches (approximately 12 microns). This advanced medical thin wall tubing design enhances softness and transparency while reducing overall catheter diameter. Its superior lubricity minimizes tissue damage and irritation during insertion and withdrawal of medical devices.
Industry-Leading Tolerance
Each ToughFlex™ custom PTFE extruded tubing undergoes rigorous inspection to ensure the highest precision. Strict quality controls keep the inner diameter within ±0.0005 inches and the wall thickness within ±0.00025 inches, setting a new benchmark among PTFE liner suppliers.
Production Consistency
The production process—including extrusion, cutting, and winding—follows strict standards to ensure uniformity and reliability. This guarantees that jMedtech’s extruded tubing medical solutions deliver stable, high-performance components for catheter custom extrusion, R&D, and medical device production.
Excellent Tensile Strength
ToughFlex™ demonstrates superior tensile strength compared to conventional extruded PTFE tubing, providing engineers with confidence in durability and long-term performance.
