Led by Jiemei Jiacheng, a subsidiary of Jiemeite, and jointly compiled with the Guangdong Medical Devices Management Society and several leading companies in the industrial chain, the group standard "Test Method for Peel Strength of PTFE Etched Liner Tubes" was officially released recently.
This is the industry's first standardized testing method established specifically for the peel strength of PTFE etched liner tubes.
What does this standard cover?
Specified Content: Methods for determining the bonding strength between PTFE etched liner tubes and other structural layers, used to evaluate the adhesive performance of PTFE etched liner tubes with other layer materials of composite catheters.
Technical Highlights: This standard provides two test methods for peel strength, clearly specifying the included sample preparation, testing procedures, equipment parameters, and result calculation methods.
Test Methods
Method | Scope of Application |
Test Method A | PTFE etched liner tube compounded with flexible materials |
Test Method B | PTFE etched liner tube compounded with rigid materials |
Scope and Applicability
PTFE etched liner tubes
Composite structure catheters
"[Lack of Standards]" Why does the industry need this standard?
For a long time, the performance evaluation of PTFE etched liner tubes has lacked a unified testing method. With the increasing application of PTFE liner tubes in interventional catheters, the industry problems caused by the absence of standards have become increasingly prominent:
Inconsistent quality evaluation benchmarks between upstream and downstream material suppliers, increasing communication and verification costs.
Downstream enterprises need to conduct extensive exploratory verification work, affecting product development and registration efficiency.
Missing product technical requirements and inspection methods affect product registration submissions.
Why did Jiemei Jiacheng "lead" the compilation of this group standard?
As a company deeply involved in PTFE and interventional catheter material solutions, Jiemei Jiacheng can stably supply PTFE liner tubes produced by three different processes, covering complex structures and extreme dimension requirements, and has long served clients in the interventional medical device field.
Possesses the technical expertise required for standard development
Based on years of:
Process development experience
Product verification data
Promoting the establishment of a unified industry evaluation method
To promote supply chain collaboration and drive the unification of industry testing methods, in December 2025, Jiemei Jiacheng submitted a standard project application to the Guangdong Medical Devices Management Society and initiated the standard development work.
What does this mean for the industry?
Unified Testing Benchmark: Establishes a unified quality evaluation system, facilitating upstream and downstream supply chain collaboration mechanisms.
Reduced Verification Costs: Decreases repetitive verification work, shortening the R&D and registration cycle.
Support for Registration and Compliance: Provides reference basis for technical requirements, inspection methods, and system audits.
Promoting Industry Standardization: Unifies evaluation methods, enhancing the quality management level of the industrial chain.
