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$6	23 (Catalog Value: 25)	31	11
PTFE Tubing (4$\times$6)	20	7	11
PFA Tubing (4$\times$6)	23	6	11

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.

(B) Flexibility Difference Image (PTFE Tubing vs. E-SJ)

(C) Non-Adhesiveness Comparison Data

Resins	Critical Surface Tension (dyne/cm)	Contact Angle for Water ($\theta$)
ETFE Fluorine	22	96
PVDF Fluorine	25	82
High Density Polyethylene	31	73
Hard Vinyl Chloride	39	68
PET	43	-
Nylon	46	54

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.

HAKKO Original Fittings for SJAST

Product Name	Materials, Characteristics
Fittings for Multi-Layer Tubing [Model Number: E-FTS-F]]	Material: SUS316L (Body) and SUS304 (Nut) It is designed by HAKKO tubing products, so you do not have to worry about fluid leakages and coming off. Specify temperature range and working pressure for each product. It is excellent in corrosion resistance (Body: made of 316L Steel Use). Since it is made of stainless steel (Passivation Treatment), you can transfer a wide variety of fluids.

PEEK (Carbon Reinforced) Nut Type Fittings [Model Number: AL]]	Material: PEEK Lightweight…Fitting weight is less than one-fifth, compared to same-size SUS joints, leading to overall weight reduction of equipment. Great Heat Resistance…PEEK material has excellent heat resistance among resins. Chemical Resistance…PEEK material has excellent resistance to a wide range of chemicals including acids, alkalis and organic solvents. Mechanical Strength…Carbon fiber is added to the engineering plastic of PEEK, which is strong in tensile and impact resistance.
