Customer Success Story – Enhancing Sealing with PTFE/FEP Heat-Shrink Tubing

Customer Background

We recently collaborated with an electronic seal company serving a major automobile manufacturer. As experts in PTFE/FEP heat shrink tubing, they approached us to improve the sealing performance of parts exposed to high-temperature corrosive liquids.

The Challenge

The customer faced issues with anti-corrosion for electronic components in harsh liquid environments. Their original solution caused poor sealing and pipe degradation over time, leading to quality problems and production delays. Quick, reliable solutions were required to ensure long-term part protection and uninterrupted production schedules.

Our solution

After inspecting the existing sealed tubes, we identified that the nozzles were not fully sealed, allowing slow liquid infiltration. To resolve this, we recommended our double-layer heat-shrinkable tubing, featuring:

• Outer layer: PTFE heat-shrinkable tube for durable external protection.
• Inner layer: High-quality FEP that fully melts at 600°C in 45 seconds to completely seal the part.
• Available in multiple colors, including black PTFE for confidential part protection.

This solution ensures superior sealing performance and protects sensitive parts effectively.

Results

Preliminary tests demonstrated significant improvements:

• Extended service life of components.
• Reduced unplanned downtime.
• Enhanced protection for various shapes and sizes using double-layer heat-shrink tubing with different shrink ratios.

By leveraging our expertise as a trusted PTFE tube manufacturer, we help clients achieve reliable, long-lasting solutions for challenging industrial applications.

2. At noon on March 16th, I received an e-mail, because the customer’s use conditions changed and the tube broke. After I understood the reason, I found that the wall thickness of the pipe that the customer wanted was not enough to cope with his current use environment. The customer placed an order in a hurry, and was not familiar with the product, and the expression of the use environment was not accurate.

As a professional manufacturer, we naturally have to help customers solve their problems. Then I proposed to customers a plan to increase the wall thickness, and provided customers with a new batch of products with thicker pipe walls for free. We will let customers try it out first. If the use requirements are met, then pay at the previous price. Although the exchange rate and raw materials have risen, we hope that customers can purchase more at ease without worrying about professional problems, so we insist on not letting customers bear the extra cost. loss.

Customers buy products for use, not for refunds. It is our responsibility to truly ascertain customer needs and reduce customer costs.

3. High procurement efficiency

“Time is money”, especially in the modern business age, people’s life is getting faster and faster, and customers’ requirements for suppliers’ response speed are getting higher and higher.

If the supplier’s response speed is too slow, it will inevitably fail to meet the delivery date and affect the customer’s experience.

In the 10,000-meter PTFE/FEP double-layer heat-shrinkable tube project, our company learned that the customer’s order demand was urgent at noon on Thursday, so before 4 pm that day, the production line with a lower emergency level was replaced with the product material required by the customer. And I contacted the colleague in charge of the transportation department to book the air freight warehouse at the first time, and four days later, the goods were loaded on the trucks prepared in advance and sent to the airport.

Corresponding production efficiency is an indicator of life for my factory. As a world-renowned plastics manufacturer, we will ensure production and delivery effectiveness at all costs.

PTFE, FEP, PFA & Fluoropolymer Tubing FAQ – Yuzhong Technologys

1. What is PTFE？

PTFE, also known as Teflon®, is the ancestor of all fluoroplastics. It offers exceptional chemical resistance, non-stick performance, and high-temperature tolerance. Its main challenge is that it does not melt, requiring specialized molding, extrusion, and welding techniques.

2. What is FEP？

FEP tubing, or fluorinated ethylene propylene, is a melt-processable fluoropolymer similar to PTFE and PFA. It provides excellent chemical resistance, low friction, high transparency, and can operate up to 200°C. Applications include laboratory piping, automatic sampling, chromatography, medical equipment, and high-temperature cable insulation.

3. What is PFA？

PFA (perfluoroalkoxy) is a melt-processable fluoropolymer with properties similar to PTFE, but with 10× higher elongation and low permeability. PFA withstands temperatures up to 260°C, offering excellent crack resistance, stress resistance, and low friction. Common applications include semiconductor components, valves, pump bushings, and insulating parts.

4. What are the differences between PTFE and FEP?

Both PTFE and FEP belong to Teflon® fluoroplastics. Key differences:

（1） PTFE: -200°C to +260°C, opaque

（2）FEP: -200°C to +200°C, transparent

（3） Both are non-stick, chemically inert, and stable under extreme temperatures

5. How can I make the rubber stick not sticky?

By applying FEP heat-shrinkable tubing coating, standard rubber rollers become non-stick. Coating sleeves are easy to apply, or Yuzhong Technology can provide professional on-site installation.

6. Why is PTFE chemically corroded?

Although PTFE, FEP, and PFA have excellent non-stick properties, chemical etching can remove fluorine atoms to improve adhesion to substrates.

7. Will PTFE, FEP and PFA become brittle at low temperatures?

No. All these fluoropolymers operate reliably down to -200°C without embrittlement.

8. Can you make PTFE tubes with similar tolerances?

Yes. If standard PTFE, FEP, or PFA tubes do not meet your requirements, we can produce tighter ID, OD, or wall thickness tolerances for specific applications.

9. What is the largest size heat shrinkable tube you can produce?

We can produce heat shrink tubing of any diameter using special welding processes. Stock size is up to 175 mm.

10. Can you produce super-thin PTFE tubing to replace Zeus Inc.?

Yes, we manufacture 0.02–0.05 mm wall PTFE tubes that meet medical-grade standards.

11. Do you have a minimum order quantity?

Yes. For spot goods, MOQ is $10. Small order fees may apply.

12. Can you supply one-off or small batch orders?

Yes. We can provide any quantity of standard products, with only setup time fees applied.

13. Do you provide design support for new concepts?

Absolutely. We offer custom injection molding and engineered plastic products solutions. Our dedicated team helps optimize designs, save costs, and drive technological innovation.

14. What other tubing products do you offer?

We also supply fluoroplastic tubes, silicone tubing, and rubber tubes for versatile industrial and medical applications.
