FEP Shrink Tubing Manufacturer
Peflon FEP heat shrink tubing is made from Fluorinated Ethylene Propylene (FEP), a material with excellent chemical and thermal stability that shrinks and wraps tightly around objects when heated to provide protection and insulation. We supply customized color, size, shrinkage ratio and length of FEP heat shrink tubing to match your application.
Peflon FEP Shrink Tubing Features
FEP (CAS RN 25067-11-2) is a melt-processable fluoropolymer whose base resin is produced by fluoropolymer leaders such as Daikin; its chemical identity is catalogued by CAS Common Chemistry. These four properties make Peflon FEP shrink tubing dependable across demanding environments.
High Temperature Resistance
FEP materials have excellent high-temperature resistance and can typically withstand temperatures in the range of -200°C to 260°C without deformation, making them well-suited for high-temperature environments.
Chemical Resistance
FEP is highly resistant to most acids, bases, solvents and other chemicals.
Electrical Insulation
FEP materials have excellent electrical insulation properties, making them ideal for preventing leakage or short circuits in wires and cables.
Transparency
FEP shrink tubing is usually transparent, making it easy to see the condition of the cable or wire inside.
FEP Shrink Tubing Types by Shrinkage Ratio
Degree of shrinkage of tubing after heating of Peflon FEP shrink tubing. Choose the shrink ratio that matches the diameter reduction your part requires.
| Shrinkage Ratio | Application |
|---|---|
| 2:1 | Suitable for general cable protection and protection of smaller electrical components; shrinkage reduces the diameter by half. |
| 3:1 | Suitable for medium-sized cables or objects. |
| 4:1 | Suitable for larger sizes or irregularly shaped parts; can be shrunk to one-quarter of the original diameter. |
FEP Shrink Tubing by Wall Type
There are two main types of Peflon FEP shrink tubing: single-wall and dual-wall. The main differences between them are in construction, application and performance.
Single Wall FEP Shrink Tubing
Suitable for general electrical insulation, protection and sealing applications.
FEP Dual Wall Shrink Tubing
Our FEP dual wall shrink tubing is suited to high-temperature work such as mechanical protection and corrosion resistance in the realm of high temperatures.
FEP Shrink Tubing Colors
Peflon FEP shrink tubing is available in a wide variety of colors.
Transparent
A common type that allows observation of the internal cable or equipment status.
Colorful
Used to identify different types of wires, connectors or equipment for easy differentiation or added aesthetics. Common colors include red, blue, yellow and black.
FEP Shrink Tubing Applications
Peflon FEP shrink tubing can be categorized into different types to meet the requirements of specific environments, depending on the needs of the particular application.
Electronic Industry
Wire and cable protection and electronic connector protection.
Chemical Industry
For the protection of chemical transportation pipelines and mechanical parts.
Medical Industry
For the protection of catheters, cables and other medical equipment.
Food Industry
FEP spiral heat shrink is widely used to protect food processing equipment because FEP material meets hygiene requirements, and perfluorocarbon resins such as FEP are covered for food contact under 21 CFR 177.1550.
What Our Customers Say
Ishita Malhotra
“We have been using Peflon’s FEP heat shrink tubing in our cable protection projects for several months now and the quality is excellent.”
Kylo James
“We use this heat shrink tubing on our wires and connectors to ensure their safety and reliability in harsh environments. Even in extreme temperatures and chemically corrosive environments, FEP heat shrink tubing holds up well. Highly recommended!”
FEP Shrink Tubing FAQ
What is FEP heat shrink tubing?
FEP heat shrink tubing is a tube made from Fluorinated Ethylene Propylene (FEP) that shrinks tightly around a wire, cable or component when heated. It provides electrical insulation, chemical resistance and mechanical protection while withstanding continuous service temperatures from about -200°C to 260°C.
Which shrink ratio should I choose — 2:1, 3:1 or 4:1?
The shrink ratio is how much the tube reduces in diameter when heated. A 2:1 ratio suits general cable protection and smaller components, 3:1 suits medium-sized cables or objects, and 4:1 suits larger or irregularly shaped parts, shrinking to one-quarter of the original diameter. Send us your recovered and supplied diameters and we will match the ratio.
What is the difference between single-wall and dual-wall FEP shrink tubing?
Single-wall FEP shrink tubing is used for general electrical insulation, protection and sealing. Dual-wall tubing adds an inner layer for high-temperature work, mechanical protection and corrosion resistance, giving a tighter, more robust seal in demanding environments.
Can Peflon supply custom colors, sizes and lengths?
Yes. We manufacture FEP heat shrink tubing in customized color, size, shrinkage ratio and length. Transparent tubing lets you inspect the cable inside, while colored tubing (red, blue, yellow, black and more) helps identify different wires and connectors.
Is FEP shrink tubing suitable for medical and food applications?
Yes. FEP is chemically inert and hygienic, so it is used to protect catheters, cables and other medical equipment as well as food processing equipment. Perfluorocarbon resins such as FEP are addressed for food-contact use under 21 CFR 177.1550.
