Customized PTFE Heat Shrink Tube Thin Wall Insulation Sleeve for Medical Catheter 4:1, 2:1 Ratio
Product Overview
Yozonetech PTFE Heat Shrink Tube is a shrinkable fluoropolymer sleeve designed for applications requiring high-temperature resistance, electrical insulation, chemical protection and a conformal fit around components.
Unlike conventional PTFE tubing, PTFE heat shrink tubing is supplied in an expanded state and contracts when heated. During installation, the tubing conforms closely to wires, terminals, connectors, sensors, metal components and other irregular surfaces, creating a compact protective layer.
PTFE provides excellent resistance to many aggressive chemicals, low friction, thermal stability and strong electrical insulation. The combination of PTFE material and heat-shrink construction is useful where conventional heat-shrink materials cannot provide sufficient temperature or chemical resistance.
Why Choose PTFE Heat Shrink Tubing
- High-temperature performance — suitable for demanding thermal environments.
- Excellent electrical insulation — suitable for wires, terminals, electrical components and sensors.
- Chemical resistance — resists a broad range of aggressive chemicals, solvents and process fluids.
- Conformal protection — contracts around the component when heated correctly.
- Low-friction surface — smooth PTFE surface can reduce installation friction.
- Thin-wall construction — provides insulation and protection without excessive bulk.
Product Construction
PTFE Heat Shrink Tube is manufactured from PTFE fluoropolymer and processed into an expanded shrinkable structure.
Basic construction: PTFE fluoropolymer → Expanded tube → Heating → Controlled shrinkage → Conformal protective sleeve.
Final performance depends on PTFE grade, expansion ratio, wall thickness, dimensions and manufacturing process. Straight or continuous lengths can be supplied according to application.

They are retained for traceability only and must not be used for freight calculations. Confirm actual packed dimensions and shipment weights. The listed net weights do not establish gross shipment weights.
Material and Color Information
The supplied catalog identifies PTFE as the base resin. It states that transparent tubing uses pure material without additives, while colored tubing uses the transparent base with the corresponding color masterbatch. Standard color is listed as transparent; other colors, dimensions and wall thicknesses can be produced to customer requirements.
The catalog includes a statement of conformity with European Union RoHS requirements. This statement is not a Yozonetech product certificate. Confirm the resin grade, additive composition, appearance and applicable compliance documentation for the exact supplied product.
The catalog instructs users not to burn the product. Follow the supplied installation instructions and product safety information.
Shrink Ratio and Sizing
The expanded ID must be large enough to pass over the component before heating, while the recovered ID must be small enough to achieve the required finished fit.
Selection principle: Expanded ID > Maximum installation diameter; Recovered ID ≤ Required finished diameter.
For connectors, terminals, splices or irregular profiles, consider the maximum installation diameter rather than only the wire or cable diameter.
Temperature Considerations
PTFE has broad temperature capability, but installation/recovery temperature and continuous operating temperature are different parameters. The tubing must be heated sufficiently to recover, while the finished assembly must remain within the allowable operating conditions of the selected PTFE grade. Final operating temperature should be confirmed against the specific product datasheet.
Electrical Insulation
PTFE Heat Shrink Tube is suitable where shrinkable installation and electrical insulation are both required. Typical uses include wire insulation, terminal insulation, connector protection, sensor protection, cable component protection and high-temperature wiring. For critical electrical systems, confirm voltage, dielectric requirements, wall thickness and operating conditions for the exact construction.
Chemical and Environmental Protection
PTFE provides strong resistance to many chemicals and solvents. After recovery, the sleeve can closely cover a component and help protect the covered area from environmental exposure. Compatibility should be evaluated against the specific chemical, concentration, temperature and exposure time.
PTFE Heat Shrink Tube vs Standard PTFE Tube
Standard PTFE Tube maintains its original dimensions and is often selected for fluid transfer or general tubing. PTFE Heat Shrink Tube is manufactured in an expanded state and contracts around a component when heated, making it particularly useful for insulation, covering and close-fitting protection.
PTFE Heat Shrink Tube vs Other Heat Shrink Materials
PTFE should not be selected simply because it is a fluoropolymer. Material selection depends on temperature, chemical exposure, shrink performance, flexibility, electrical requirements and cost. Yozonetech can evaluate PTFE, FEP and other fluoropolymer shrink tubing according to the application.

1. Polytetrafluoroethylene (PTFE) convoluted tube is made of modified standard PTFE. Compared with most fluoropolymers, it has excellent bending life performance and greatly improves the resistance to stress cracking.
2. Compared with standard materials, the PTFE spiral tube has fewer pinholes and lower penetration, which makes it an excellent choice for the transmission of fine chemicals and highly searchable gases (such as chlorine) .
3. PTFE can be made into corrugated PTFE pipe, which has excellent flexibility. Anti-static design (black) or straight end (for connectors/accessories) are also available. In addition to PTFE, we also provide PFA, FEP and PVDF bellows.
We can also provide stainless steel braided corrugated PTFE tube, whose engineering strength will be greatly increased
Key properties of convoluted PTFE tubing:
• UV-resistant (does not age)
• Almost absolutely chemical inert
• FDA- approved (suitable for food industry)
• Applications from -50 up to 260°C
• No attachment (easily to clean)
• Vacuum lasting up to 90%
• Electric isolated (high dielectricity)

PTFE Etching Tubing OEM Manufacturer for Medical
Medical Tubing Extrusion Product Description
PTFE often needs to be mixed with other materials, but due to its famous smooth surface, it is difficult to combine with other materials. The purpose of fluoropolymer etching is to change the surface characteristics of PTFE, after treatment, it can be combined with other materials, whether it is plastic, metal, composite material or ceramic.
The inherent bonding of fluoropolymers results in extremely low friction. In its unchanged state, the bonds of these polymers are so stable that it is difficult for them to bond with anything, even for a short period of time. When the etching process changes the carbon-fluorine bond of the PTFE bottom layer, the surface of the PTFE changes. After the PTFE is etched, its surface will have more friction, and it can be glued, molded or glued to other materials. It also allows the PTFE tube to be printed or engraved.
YOZONE-Technology provides the following key solutions for PTFE, FEP, PFA and PEEK products. So, today we will introduce you our quality Extruded Tube below:
PTFE tube supplier Extruded tubing is a versatile and widely used product in various industries. It is a continuous length of material that is formed by forcing it through a die, resulting in a hollow cylindrical shape.
