In the world of industrial components, where reliability under extreme conditions is non-negotiable, PTFE (Polytetrafluoroethylene) tubing stands as a benchmark material. At Kaxite, we have engineered our premium PTFE tubing to meet and exceed the rigorous demands of modern industry. Our tubing is not just a piece of plastic; it's a precisely manufactured component designed to ensure system integrity, safety, and longevity in the most challenging environments, from chemical processing to semiconductor manufacturing and medical device assembly.
Kaxite's dedication to material science and advanced extrusion processes results in tubing that offers an unmatched combination of properties. We understand that your applications require more than just a standard product—they require a solution built with precision, consistency, and deep technical expertise.
The exceptional performance of PTFE stems from its unique molecular structure. Kaxite leverages this inherent potential, delivering tubing with consistent, high-grade characteristics across every production batch.
Our product range is designed to provide precise solutions. Below are the standard specifications for our seamless, extruded PTFE tubing.
| Parameter | Standard Range | Key Notes |
|---|---|---|
| Standard Color | Natural (Translucent White), Black | Other colors available upon request for coding and identification. |
| Inside Diameter (ID) | 0.5 mm to 50 mm (0.02" to 2.0") | Tight tolerances available (e.g., ±0.05mm) for critical applications. |
| Wall Thickness | 0.2 mm to 5.0 mm (0.008" to 0.197") | Optimized for pressure rating and flexibility requirements. |
| Standard Length | Up to 100 meters per coil (continuous) | Can be cut to specific lengths, spooled, or provided as straight sticks. |
| Operating Temperature | -200°C to +260°C (-328°F to +500°F) | Short-term peak tolerance up to 300°C (572°F). |
| Pressure Rating (Typical) | Varies with ID and Wall Thickness | Example: For a 4mm ID x 1mm wall tube, burst pressure >50 bar (725 psi). Consult our engineers for specific data. |
| Surface Finish | Smooth, extruded finish | Special finishes (e.g., etched for adhesive bonding) can be provided. |
| Standards Compliance | FDA, USP Class VI, RoHS, REACH | Certificates of Compliance provided. Medical-grade and high-purity versions available. |
Kaxite offers a variety of PTFE tubing grades to suit specific application needs.
Q: What is the primary advantage of PTFE tubing over other plastic tubings like PVC, PU, or Nylon?
A: The primary advantage is its unmatched combination of extreme chemical inertness and exceptional temperature range. While PVC, PU, and Nylon have specific strengths, they cannot withstand highly corrosive chemicals or temperatures above 100-150°C for prolonged periods. PTFE tubing operates reliably from deep cryogenics up to 260°C while resisting attack from almost all industrial chemicals, making it the ultimate choice for severe service conditions.
Q: Can Kaxite PTFE tubing be used for food contact or medical applications?
A: Yes, absolutely. Kaxite produces specific grades of PTFE tubing that comply with relevant regulations. Our medical-grade tubing meets FDA standards and USP Class VI requirements for biocompatibility, making it suitable for peristaltic pumps, fluid transfer, and device components. For food and beverage applications, we offer FDA-compliant grades that ensure no contamination or leaching into the product stream.
Q: How do I connect or fit PTFE tubing? Does it require special fittings?
A: Due to its slippery, non-stick surface and flexibility, securing PTFE tubing requires careful consideration. Common methods include using compression fittings (e.g., Swagelok-type) with ferrules specifically designed for soft tubing, push-to-connect fittings with gripping teeth, or flared/beaded ends created with a specialized tool. It is crucial to avoid using standard barbed fittings, as the tubing can easily slip off under pressure. Our technical team can advise on the best connection method for your application.
Q: Is PTFE tubing flexible? Can it be bent sharply?
A: PTFE tubing is semi-flexible. It has good column strength but a relatively large bend radius compared to very soft plastics like silicone. Sharply bending a PTFE tube can kink it, permanently obstructing the flow path. The minimum bend radius depends on the tubing's diameter and wall thickness; typically, it should be no less than 5 times the outer diameter. For tight spaces, pre-formed bent tubes or the use of elbows and connectors is recommended.
Q: What is the difference between PTFE, FEP, and PFA tubing? Are they interchangeable?
A: While all are fluoropolymers with excellent chemical resistance, key differences exist. PTFE has the highest continuous use temperature (260°C) but is opaque and must be processed by sintering, not melt-extrusion. FEP is melt-processable, transparent, and has a lower temperature limit (205°C). PFA shares PTFE's high temperature rating (260°C) and is melt-processable, offering excellent clarity and purity, often used in high-purity semiconductor applications. They are not directly interchangeable; the choice depends on the required temperature, clarity, processing needs, and budget. Kaxite supplies all three materials.
Q: How does Kaxite ensure the quality and consistency of its PTFE tubing?
A: Kaxite implements a rigorous quality management system from raw material sourcing to final shipment. We use 100% virgin PTFE resins from reputable suppliers. Our in-line production monitoring controls dimensions (OD, ID, wall thickness) with laser gauges. We perform batch testing for critical properties like melt flow index, density, and thermal stability. Furthermore, we can provide material certifications, lot traceability, and custom testing protocols to meet customer-specific quality assurance requirements.
Q: Can you manufacture PTFE tubing with custom colors or printing/marking?
A: Yes. Beyond standard natural and black, Kaxite can produce tubing in a range of colors for system identification, safety coding, or branding purposes. We can also apply permanent printing or laser marking on the tubing surface to indicate part numbers, size, batch codes, or flow direction, enhancing traceability and assembly accuracy in complex systems.
The versatility of our tubing makes it a critical component across numerous sectors.
