If you are in procurement at a medical device OEM then you are well aware that quality consistency, traceability, regulatory compliance, and supply chain delays can keep you up at night. That is why when it comes to choosing a PTFE Liners and Tubing supplier, there are several benefits to choosing a vertically integrated manufacturer, such as Hydromer®, Inc. In this article we will discuss what vertically integrated PTFE manufacturing is and its benefits.
What is Vertically Integrated PTFE Manufacturing?
Fully integrated, PTFE liners and tubing manufacturers perform all steps of the supply chain process in-house. This includes everything from resin sourcing to testing and regulatory compliance. Below are the stages of PTFE liners and tubing manufacturing that are handled by a vertically integrated manufacturer.
Stages of the Vertically Integrated PTFE Manufacturing Process
Vertically integrated manufacturers perform all steps in the sourcing, manufacturing, and quality process. These include the following:
- Resin Sourcing – the manufacturer secures a supply of raw PTFE powder or granular PTFE.
- In-House Compounding – this is where the manufacturer compounds the resin with additives and/or fillers in order to change its properties
- Extrusion and sintering – the manufacturer performs extrusion, casting, etc. processes and that convert compounded PTFE into liners and tubing products.
- Processing and Value-Add Activities – the integrated manufacturer takes the extruded and sintered liners and tubing and performs processes, such as etching (to allow them to bond to jackets), adding reinforcement layers, cutting, etc. These activities are handled in-house to ensure specifications are met and consistency is ensured.
- Testing & Inspection – as a last step the vertically integrated manufacturer will handle all quality testing and regulatory compliance requirements.
Biggest Benefits of Vertical Integration in PTFE Liners and Tubing Supply
Securing a steady supply of high-quality, consistent PTFE liners and tubing for medical devices is absolutely critical. Using non-vertically integrated suppliers may cause issues. These can include a lack of dimensional precision and consistency, difficulty with traceability, and supply disruptions. Relying on a vertically integrated manufacturer has several benefits. These include the following:
1. Dimensional Precision and Product Consistency
Variations in wall thickness can affect catheter performance, such as causing kinks, that can have disastrous results. Vertically integrated manufacturers have control over the entire process, from the compounding formula to the extrusion process. They can control the tolerances extremely tightly. This ensures consistency and precision, which a non-integrated supplier just can’t achieve because they do not have control over the entire process.
2. Better Quality Control and Traceability
Similarly, vertically integrated manufacturers have control of the product from the raw material stage to the final finished liner and tubing. As such, they can provide extensive traceability that a non-integrated supplier just does not have the ability to do. The issue can be traced easier than trying to coordinate and investigate with a third-party partner.
3. Customization and R&D
One of the biggest benefits of a fully-integrated PTFE manufacturer is their ability to customize products to your exact needs. Since the supplier controls the entire process they have the ability to modify the product as needed, such as a custom compound, custom wall thickness, etc. Formulas can be produced and tested rapidly, vs working through a middle-man.
Non-integrated suppliers have limited ability to do this, as they are not controlling every step of the process.
4. De-Risking the Supply Chain
Integrated manufacturers control the entire supply chain and manufacturing process. This means they are insulated from most of the risks of a supplier with a fragmented supply chain. This provides reliability as well as faster lead times.
5. Lower Costs
Even with all of these benefits vertically integrated manufacturers can offer higher quality products with better lead times at lower costs. This is because there is no middle-man, and there are no middle-man markups at every stage of the process.
How Vertically Integrated PTFE Manufacturing Meets the Priorities of OEMs
It is easy to see that there are several benefits of using a vertically integrated supplier. But how do these benefits help medical device OEMs meet their ultimate goals of regulatory compliance, patient safety, and time-to-market? That is what we look at next.
1. PTFE Vertical Integration Ensures Product Dimensional Precision and Consistency
OEM Priority: ensuring consistency and extremely tight tolerances to prevent catheter kinking, product failure, etc.
Why Vertical Integration Matters:
Ensuring consistency with PTFE liners and tubing is critical, but if not done correctly it can be difficult. The properties of the final product depend on many things, including how the raw materials are stored, the accuracy of the compound recipe, and the extrusion process. If any of these change the product can change, for instance changes in wall thickness, and the results of this can be huge.
Integrated manufacturers source and store the raw materials. They do their own compounding and control the recipe to ensure it is exactly right. Then they control the extrusion process and everything else after. All of these things ensure consistency and extremely tight tolerances. This is something that a non-integrated supplier does not have the ability to do.
2. Traceability & Regulatory Compliance (FDA/ISO 13485)
OEM Priority: the ability to trace every component back to its source and comply with FDA/ISO 13485. OEMs need to be able to meet this requirement easily.
Why Vertical Integration Matters:
Vertically integrated manufactures a single Quality Management System (QMS) manages the entire product from start to finish. Every material and step is documented in one place. This means that instead of having to audit multiple suppliers in the supply-chain, the OEM only has to audit one, single supplier. This reduces risk, cost, and greatly simplifies the process.
3. Limiting Product Delays and Supply Chain Risk
OEM Priority: Sourcing PTFE liners and tubing from non-integrated suppliers can present risks of supply issues, line shutdowns, and delays from shipping products between multiple suppliers. All of these run the risk of product delays and late launch times.
Why Vertical Integration Matters:
Vertically integrated manufacturers have raw material supply sources secured and perform all steps of the process in-house. This reduces the chances of supply chain disruptions. It also reduces processing time since products are not being shipped from one supplier to another and back. Also, any problems that may arise can be addressed on the spot vs coordinating fixes between multiple suppliers in the process.
Vertically Integrated PTFE Manufacturing: Value Matrix
| What the Medical OEM Fears | The Fragmented Supply Chain Risk | The Vertically Integrated Solution |
| Catheter kinking / failure | Variations introduced by buying raw materials from changing third-party compounders. | In-house compounding ensures uniform polymer morphology and ultra-precise tolerances. |
| FDA Audit Failures | “Finger-pointing” between the extruder, the etcher, and the final processor if a defect occurs. | Single QMS provides flawless, unbroken lot traceability from raw resin powder to final shipped component. |
| Launch Delays | Weeks spent waiting for material to ship between sub-tier vendors for secondary processing. | All-under-one-roof capabilities (extruding, etching, braiding, tipping) shrink lead times. |
Conclusion
Vertically integrated PTFE manufacturing takes a highly complex component supply chain and turns it into a single, predictable process. Integrated suppliers control the entire process, from raw PTFE sourcing and compounding and extrusion to final secondary processing under one roof. Integrated suppliers eliminate risks, time and cost and deliver consistency and precision, excellent traceability, and fast speed to market that medical OEMs require. As a result, this all-in-one approach is the ultimate strategy for de-risking device development.
