Mangas de tubagem termorretráctil PFA para semicondutores Anti-UV e resistência a altas temperaturas
Product Overview
PFA Heat Shrink Tube is a heat-activated fluoropolymer sleeve designed to conform around components, connections, wires, terminals, tubing or other assemblies when heated. Compared with general-purpose heat shrink materials, PFA is selected when chemical resistance, thermal performance, cleanliness and fluoropolymer properties are important.
For demanding process environments, the key value of PFA heat shrink tubing is not simply shrinkage. The recovered sleeve forms a continuous protective layer while retaining the characteristic chemical resistance and high-temperature capability associated with PFA. This makes it suitable for applications where contamination control, aggressive chemicals or elevated operating temperatures can limit conventional heat-shrink materials.
Use the dimensional tables below for initial size selection. Confirm shrink ratio, recovery temperature and operating limits against the approved specification for the required PFA grade and construction.
Caraterísticas principais
High-purity fluoropolymer material for demanding process environments; Excellent resistance to many aggressive chemicals and process media; Heat-shrinkable construction for conformal protection around irregular assemblies; Low surface energy and smooth surface for easier cleaning and reduced adhesion; Strong electrical insulation performance for wire, cable and component protection; High-temperature capability compared with conventional polymer heat-shrink materials; Good transparency is possible with suitable PFA grades, supporting visual inspection; Suitable for custom dimensions and application-specific OEM production.
Why Choose PFA Heat Shrink Tubing
PFA heat shrink tubing is intended for applications where the protective sleeve itself must withstand a demanding environment. A conventional polyolefin sleeve may provide economical insulation, but it may not offer the required chemical resistance or temperature capability. PFA provides a fluoropolymer-based alternative for more severe service.
The selection should be based on the complete assembly rather than on the tube diameter alone. Installation diameter, recovered diameter, wall thickness, shrink ratio, temperature exposure, chemical environment, electrical requirements and installation method all influence the correct construction.
Product Construction
The product is manufactured from PFA fluoropolymer in a heat-shrinkable tubular construction. The tube is supplied in an expanded state and contracts toward its designed recovered dimensions when exposed to the specified heating conditions.
Base material: PFA fluoropolymer; Form: expanded heat-shrinkable tube / sleeve; Surface: smooth fluoropolymer surface; Standard appearance: natural/translucent to transparent depending on grade and wall thickness; Supply form: straight cut lengths or continuous lengths subject to product design; Construction can be tailored for dimensional, wall-thickness and installation requirements.

Wall thickness is specified after recovery. Standard packaging length is 1 m.
The ≥82 mm expanded ID / ≤24 mm recovered ID entry is retained from the shared specification table and requires confirmation before ordering. Do not infer a universal shrink ratio from the listed dimensions.
The shared sizes do not establish identical material performance or recovery conditions for FEP and PFA. Confirm the PFA grade, recovery instructions, dimensional acceptance limits and application requirements with the quotation.
Additional PFA Size Options
The following recovered ID and wall thickness combinations are additional size examples. Specify the expanded ID, recovery requirements and required length when requesting a quotation.
Recovered ID mm Wall thickness mm 1.6 0.15 3.6 0.1 8 0.3 16 0.25 30 0.35 130 0.5 180 0.55 200 0.6 Other dimensions, lengths and tolerances can be evaluated to suit drawings or samples. Stock availability and production lead time are confirmed at quotation.
Pressure and temperature limits depend on the exact PFA grade, construction, dimensions, installation and service conditions. Confirm the requirements for the selected product.
Shrink Ratio and Dimensional Selection
The most important sizing principle is to evaluate both the expanded and recovered dimensions. The expanded inside diameter must be large enough to pass over the component during installation, while the recovered inside diameter must provide the required fit after heating.
Expanded ID: larger than the maximum installation diameter, with suitable installation clearance; Recovered ID: compatible with the finished assembly diameter; Wall thickness: selected according to insulation, protection, mechanical and thermal requirements; Shrink ratio: confirm against the approved product datasheet rather than assuming one ratio for the whole PFA range; Length: account for assembly geometry, cut tolerance and axial movement during recovery; For irregular parts, provide a drawing or sample so the recovered fit can be evaluated.
High Purity and Process Cleanliness
For semiconductor, analytical, chemical and other controlled environments, PFA is often chosen because of its strong chemical resistance and fluoropolymer cleanliness characteristics. The heat-shrink format extends these benefits to protective sleeves around components and connections.
Cleanliness requirements should be specified separately. If the application requires controlled particulate, extractables, trace-metal, ionic or other contamination limits, the customer should identify the required standard and the supplier should confirm the exact material grade, processing controls and documentation.
Resistência química
PFA provides broad resistance to many acids, bases, solvents and aggressive process chemicals. This is particularly valuable when the sleeve is exposed to the surrounding process environment or when it is used to protect a sensitive connection from chemical attack.
Chemical compatibility is application-specific. Temperature, concentration, exposure time, mechanical stress and permeation can change material performance. For critical service, compatibility should be confirmed for the actual chemical and operating conditions.
Isolamento elétrico
PFA is an electrically insulating fluoropolymer and can be used as a protective sleeve for wires, terminals, splices and electrical components. The heat-shrink construction allows the material to conform around the assembly and provide a continuous insulating barrier.
Wire and cable insulation reinforcement; Terminal and connector protection; Splice and joint insulation; Protection of sensitive electrical components; High-temperature electrical isolation where conventional shrink materials are unsuitable.
Temperature Performance
PFA is selected for high-temperature environments, but heat-shrink installation temperature and service temperature are different parameters. The recovery process must be performed within the approved processing window, while the finished assembly must remain within the continuous and short-term temperature limits of the specific product.
Recovery temperature: confirm from the exact product specification; Continuous operating temperature: confirm from the exact PFA grade and construction; Short-term exposure: evaluate separately where thermal excursions occur; Mechanical load at elevated temperature: consider when the sleeve carries or restrains a component; Chemical exposure at elevated temperature: verify compatibility under the actual process conditions.

Fluid Use and Installation
Suitable fittings and fluids vary. For liquids, keep instantaneous impact pressure within the maximum operating pressure. Excess impact pressure may damage joints or rupture the tube. Abnormal temperature rise caused by adiabatic compression may also cause rupture.
Avoid shaking or vibrating conditions. Operating pressure must remain below the allowable tube and fitting limits. Long-term or high-temperature use can change the material and cause leakage; inspect and maintain the installation regularly.

Consistent tube performance depends on resin selection, extrusion, dimensional control and final inspection. For high-purity applications, process cleanliness and packaging are additional parts of the specification.
Process Quality Focus Material Selection Select PFA resin/grade according to purity, chemical, thermal, electrical and regulatory requirements. Material Preparation Condition and prepare material according to the selected extrusion process. Extrusion Control tooling, temperature and process parameters to establish stable tube geometry. Sizing & Cooling Control OD, ID and wall geometry during sizing and cooling. Dimensional Inspection Check ID, OD, wall thickness, length and appearance against the agreed specification. Surface / Cleanliness Check Evaluate surface condition and cleanliness requirements where the application demands them. Cutting / Coiling Supply controlled straight lengths or coils with suitable protective packaging. Final Inspection Verify dimensions, appearance, labeling, packaging and order-specific requirements before shipment. Why Choose Yozonetech？

Frequently Asked Questions
1 How do I choose the right PFA tubing size
Specify the required outer diameter (OD) and inner diameter (ID), together with your fitting dimensions and flow requirements. Send us your existing tube specification or equipment drawing, and we can review the corresponding metric or inch option before quotation.
2 Can I order both metric and inch PFA tubing
Yes. Our listed range includes 13 metric sizes and nine inch models. Provide the exact OD and ID rather than relying only on the nominal size, so we can confirm the tubing matches your connections.
3 Can you supply a size that is not listed
Send your required OD, ID, tolerances, length and quantity. We will review production feasibility and confirm availability, minimum order quantity and lead time for the requested size.
4 What working pressure should I specify
Provide your normal and maximum pressure, operating temperature and fitting details. The permitted pressure varies by tube size and temperature. We can review the relevant pressure group and identify any specifications that need confirmation before you order.
5 Can PFA tubing operate at 260°C
The listed maximum operating temperature is 260°C, with reduced pressure limits at elevated temperatures. Tell us your temperature, pressure and exposure duration so we can review the proposed tube and connection requirements together.
6 Is this PFA tubing suitable for my process fluid
The operating index lists air, water and inert gas. For other media, send the chemical name, concentration, temperature and cleaning agents. We can review the material requirements and identify whether additional compatibility evidence is needed.
