PTFE High Rigid Transparent Tube for Medical Devices

Description

Short Description

The PTFE High Rigid Transparent Tube is designed for catheter components, guidewire channels, instrument access, fluid transfer, electrical insulation, and precision medical device assemblies.

• High rigidity and stable shape
• Smooth, low-friction inner lumen
• Custom OD, ID, wall thickness, and length
• Optional surface etching for bonding
• Class 10,000 cleanroom production available

Product Overview

The PTFE High Rigid Transparent Tube is manufactured for medical device applications requiring controlled rigidity, precise lumen dimensions, chemical resistance, electrical insulation, and a smooth internal surface.

Its rigid construction provides stable shape retention during insertion, assembly, fluid transfer, and component positioning. The smooth PTFE lumen reduces resistance when guidewires, instruments, fluids, sensors, or fine electrical wires pass through the tube.

Depending on the tube dimensions, wall thickness, and production process, the natural PTFE appearance may range from translucent to semi-transparent. FEP or PFA tubing is also available for applications requiring higher optical transparency.

Fobos Polymer manufactures PTFE high rigid transparent tubes according to customer drawings, samples, dimensional requirements, assembly conditions, and intended medical applications.

Available Specifications

These are existing production sizes. Other outer diameters, inner diameters, wall thicknesses, lengths, and dimensional tolerances can be developed according to customer drawings.

Final tolerances should be confirmed according to the required tube size, production quantity, assembly method, and intended application.

General Technical Information

The general PTFE properties above are provided for reference. Final dimensions, cleanliness, material documentation, sterilization compatibility, and regulatory requirements must be confirmed for each medical device project.

Product Advantages

High Rigidity and Shape Retention

The tube provides better shape retention than conventional soft tubing. It is suitable for applications where straightness, controlled insertion, accurate positioning, and assembly stability are important.

Smooth, Low-Friction Lumen

PTFE has a naturally low coefficient of friction. Its smooth inner lumen helps guidewires, instruments, fluids, sensors, and fine electrical wires move through the tube with reduced resistance.

Excellent Chemical Resistance

PTFE resists many acids, alkalis, solvents, water-based fluids, and process chemicals. This makes it suitable for demanding medical device manufacturing and operating environments.

Wide Operating Temperature Range

PTFE typically maintains stable material performance from approximately -200°C to +260°C. The actual operating limits depend on tube dimensions, mechanical loading, assembly structure, and sterilization conditions.

Electrical Insulation

The dielectric properties of PTFE make the tubing suitable for protecting wires, sensors, electrodes, and electrical components used in medical instruments.

Optional Surface Etching

Untreated PTFE has a naturally non-stick surface and is difficult to bond. Chemical etching can be provided when the tubing must be bonded to suitable adhesives, metals, polymers, or other device components.

Medical Applications

The PTFE High Rigid Transparent Tube can be customized for:

• Catheter shafts and catheter components
• Guidewire pathways
• Instrument access channels
• Endoscopic device components
• Minimally invasive surgical instruments
• Fluid and drug-delivery assemblies
• Sensor and electrode insulation
• Fine wire protection and routing
• Medical equipment assemblies
• Precision protective sleeves

The final PTFE grade, dimensions, surface condition, cleanliness level, packaging, and sterilization requirements should be selected according to the intended medical device.

Customization Options

Fobos Polymer supports custom production based on customer drawings and samples, including:

• Outer diameter and inner diameter
• Wall thickness
• Tube rigidity
• Fixed or customized length
• Dimensional tolerances
• Natural or customized color
• Smooth or etched surface
• Cutting and end finishing
• Cleanroom production
• Customized packaging
• Prototype and sample quantities
• Batch production after sample approval

For new medical tubing projects, sample evaluation is recommended before finalizing mass-production specifications.

Class 10,000 Cleanroom Manufacturing

Medical tubing projects requiring controlled manufacturing conditions can be produced in Fobos Polymer’s Class 10,000 cleanroom.

Available manufacturing and quality services include:

• Precision PTFE tube extrusion
• Prototype and sample development
• Fixed-length cutting
• Dimensional inspection
• Surface etching
• Controlled production and packaging
• Production according to customer drawings
• Batch manufacturing after sample approval

Raw-material information, dimensional inspection records, and applicable quality documentation can be supplied according to project requirements.

Fobos and SUKO can also provide relevant CE, ISO, and SGS documentation where applicable. Final regulatory suitability must be evaluated according to the selected PTFE grade and finished medical device.

Customer Development Case

A medical device manufacturer in Shenzhen requested four specifications of custom PTFE tubing for dimensional and assembly evaluation.

During the initial development stage, five sample pieces of each specification were manufactured. The customer used the samples to evaluate tube rigidity, lumen dimensions, component fit, insertion performance, and suitability for the intended medical assembly.

This sample-first process helps identify dimensional or assembly issues before volume production and reduces the risk of ordering unsuitable tubing specifications.

FAQ

Is the PTFE High Rigid Transparent Tube completely clear?

Natural PTFE is normally translucent or semi-transparent rather than optically clear. Its actual appearance depends on the wall thickness, tube dimensions, raw material, and production process. FEP or PFA may be recommended when full optical transparency is required.

What is the difference between this tube and conventional soft PTFE tubing?

The high-rigid tube provides better shape retention, straightness, and positioning stability. It is designed for medical assemblies where the tube must resist unwanted bending or deformation.

Can you customize the OD, ID, and wall thickness?

Yes. Outer diameter, inner diameter, wall thickness, length, tolerance, and surface treatment can be customized according to customer drawings.

Can this tubing be used in catheter components?

Yes. It can be customized for catheter components, guidewire channels, instrument pathways, insulation sleeves, and other medical device assemblies.

Can the PTFE tube be bonded to other components?

Untreated PTFE is difficult to bond. Chemical etching can be provided to improve adhesion to suitable adhesives, metals, and polymer components.

Can you provide fixed-length tubes?

Yes. Fixed-length cutting is available according to the required dimensions, tolerances, assembly process, and packaging requirements.

Can you manufacture samples before mass production?

Yes. Sample production is recommended for verifying dimensions, rigidity, component fit, insertion performance, and functional requirements before confirming a batch order.
