    • Flexible Fluorine (ETFE) Resin Tubing Anti-Static Type [Model Number: SJAST]

    Flexible Fluorine (ETFE) Resin Tubing Anti-Static Type [Model Number: SJAST]

    image_SJAST01
    image_SJAST02

    Multi-Purpose / Anti-Static Chemical Resistance Tube | Single-layer teflon tubing is hard (stiff) and easy to break. Our Flexible Fluorine (ETFE) Resin Tubing Anti-Static Type is an alternative tubing for a teflon tubing.

    Characteristics

    • Anti-Static…Since Anti-Static material is added to the outer layer of SJAST, SJAST eliminates the static electricity that badly affects the results from chromatography, biochemical analyzers and precision instruments. However, please note that volume resistance value is 1010 to 1012, which is the material data, not tubing data.
    • Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, SJAST is resistant to most of the chemical substances. For more information, please refer to chemical resistance data.
    • Flexibility…Due to the laminated structure, compared with a single-layer fluorine tubing, SJAST is superior in flexibility. This improves your work efficiency.
    • Hard to Break…Unlike a single-layer fluorine tubing, SJAST is less likely to break. (Even if it breaks, you can restore its shape to some extent.)
    • Higher Non-Adhesiveness…Since ETFE fluorine resin is superior in terms of water-proof, you can wash out the fluids very easily.
    • Abrasion Resistance…Fluorine resin (inner layer) shows high levels of abrasion resistance. Thus, you can even transfer chemical slurry.
    • Plasticizer-Free…SJAST does not contain plasticizer (an elution material) at all. SJAST is an oil-free tubing.
    • Non-PVC…SJAST is made of non-PVC materials.
    • Low Elution and Low Odor…Since SJAST contains very low levels of elution and odor, it is highly recommended for use in transfers of cosmetics.
    • High Purity…Fluorine resin does not contain any additives such as plasticizer, so SJAST is suitable for transferring high purity chemical fluids.
    • Transparency…SJAST enables you to check the fluid very easily.
    • RoHS2…SJAST is compliant with RoHS2 requirements (Directive: (EU) 2015/863). (RoHS 2 Compliant means that SJAST does not contain RoHS 2 10 restricted substances or it does not exceed the upper threshold of RoHS 2 10 restricted substances.) Certificate is available on request.

    Technical Information

    (A) Flexibility Comparative Data

    Test Sample
    Minimum Bend Radius (mm)
    Amount of Deflection (mm)
    Kink Resistance (mm)
    SJAST-4$\times$623 (Catalog Value: 25)3111
    PTFE Tubing (4$\times$6)20711
    PFA Tubing (4$\times$6)23611

    Minimum Bend Radius
    Deflection (Flexibility)

    Kink Resistance

    Results: “Amount of Deflection” is one indication of flexibility. Flexibility varies depending on hose (tubing). The larger the amount of deflection is, the more flexible the hose (tubing) is. Thus, SJAST is much more flexible than PTFE and PFA tubing.

    Contact Angle Image

    Critical Surface Tension: The surface tension of the assumed fluid which has the contact angle of zero against solid.

    Results: Since the lower value of “Critical Surface Tension” and higher value of “Contact Angle for Water” show higher non-adhesivenss, ETFE fluorine material shows the highest non-adhesiveness.
