With the continuous advancement of minimally invasive implantable medical technology, the performance of catheter systems is defining the limits of therapeutic possibilities. Widely adopted in medical implantable catheters and devices, PTFE Liner exerts a vital influence on catheter system performance in terms of mechanical strength, flexibility, dimensional tolerance and surface treatment.
Breaking out of its leading position in domestic medical coating industry, jMedtech has devoted itself to the R&D and production of high-grade medical PTFE Liner. With manufacturing advantages in micro-precision, stable production and wide adaptability, jMedtech delivers refined PTFE Liner solutions. We provide reliable core materials for sophisticated and high-value minimally invasive medical procedures, winning wide recognition and trust from medical device engineers worldwide.
Precision Manufacturing for Delicate Life Scenarios
High precision ensures consistent internal catheter space, lowers assembly difficulty, optimizes overall product quality, and enables smooth and stable device operation. It effectively reduces the risks of intraoperative jamming and tissue injury.
jMedtech controls the dimensional tolerance of PTFE Liner from multiple aspects:
In terms of production equipment, jMedtech adopts high-end imported machines combined with rich R&D and production experience to optimize the production line, boosting efficiency while upgrading product precision.
In manufacturing technology, our R&D team standardizes the full-process operation including raw material selection, forming, cooling, shaping and environmental control to calibrate product precision strictly.
A complete set of strict quality control measures enables jMedtech to manufacture PTFE Liner with micron-level precision:
Inner diameter tolerance: as low as ±0.0003” (7.6μm)
Wall thickness tolerance: as low as ±0.00025” (6.3μm)
jMedtech is one of the first domestic enterprises to realize the free extrusion process with a wall thickness of 0.0005”. We also supply PTFE Liner with ultra-thin wall (WT=0.0015”/0.038mm) for large inner diameter sizes ranging from 4.0mm to 11.0mm.
We have mastered the manufacturing technology for ultra-small inner diameter PTFE Liner (ID=0.0039-0.0138”/0.1-0.35mm).
By pushing the limits of production technology, jMedtech continuously iterates high-precision PTFE Liner products. Our precision manufacturing lays a solid foundation for patient health, reaching the most delicate scenarios of clinical treatment with high-standard medical materials.
Process Control to Improve Intraoperative Reliability
Operating strictly in accordance with the ISO 13485 quality management system, jMedtech has built a 4000+ ㎡ Class 10,000 clean workshop, equipped with advanced manufacturing equipment and high-precision testing instruments.
The whole production process, from raw material feeding to final packaging, is completed inside the Class 10,000 clean workshop to ensure stable and consistent product quality via refined process control.
We have established a rigorous quality management system that regulates every production link following international standards. Clear quality specifications and responsibility division are implemented throughout order requirement analysis, process debugging, production monitoring and pre-shipment inspection, guaranteeing stable and reliable PTFE Liner quality.
PTFE features low surface energy, which leads to weak and unstable bonding with other device components, easily causing delamination or peeling and compromising downstream medical device quality.
To solve this problem, jMedtech adopts proprietary surface etching technology to modify the surface property of PTFE Liner, greatly improving PTFE adhesion performance.
Peel strength tests show that compared with other brands, jMedtech etched PTFE Liner delivers superior bonding strength and tensile resistance for finished catheters. It effectively avoids delamination and stabilizes the overall performance of customers’ end products.
Customized Solutions for Broader Application Scenarios
1. Full Coverage with Multiple Processes & SpecificationsjMedtech realizes full coverage of PTFE Liner in diverse types and specifications.
We master three core production technologies: free extrusion, mandrel extrusion and dip coating. Key indicators including inner diameter, wall thickness and tolerance can be flexibly adjusted.
Customization is available in dimension, mechanical performance and other parameters, fully meeting customer demands from ultra-fine to large-bore catheter applications.
Customizable dimensions and performance options:
High yield strength series
High elongation series
Customized etching effect
And more customized specifications
While expanding dimensional and performance ranges, the jMedtech professional team assists customers in overcoming technical bottlenecks throughout project cooperation.
For instance, during the feasibility verification of jMedtech PTFE Liner in a customer’s passive urinary sheath project, our team provided innovative technical solutions to break through R&D bottlenecks, accelerate project progress and reduce development costs.
Furthermore, jMedtech PTFE Liner is widely applied in cardiovascular intervention (micro catheters, aspiration catheters, guiding catheters, support catheters, etc.), neurointervention (neuro aspiration catheters, neuro micro catheters, distal access catheters, guiding catheters, etc.) and urological intervention steerable catheters. Our products have passed verification by over 200 clients, helping partners develop high-end and competitive implantable medical devices.
In the era of continuous innovation in medical devices, PTFE Liner is far more than a simple component — it serves as a critical link between device operational performance and patient health.
Adhering to the philosophy that Medical materials are the core of healthcare innovation, jMedtech keeps advancing towards miniaturization, stability and versatility. We commit to manufacturing high-precision, high-stability and highly adaptable PTFE Liner, repaying the industry’s trust with premium medical material solutions.
