Applications
- For Wide-Format Ink-Jet UV Printers (Water-Based UV Inks [Non-Aggressive Inks] )
Functions
Non-PVC
Chemical Resistance
Flexibility
UV Cut
Ink Resistance
Oxygen Barrier
Characteristics
- Ink Resistance...Since inner and outer layers are made of polyethylene resin, E-WBT-UV shows resistance against water-based ink.
- High Barrier...Since the middle layer is composed of barrier resin, the value of dissolved oxygen remains low.
- UV Cut…By cutting ultraviolet, E-WBT-UV is suitable for transferring UV-curable inks.
- Flexibility...Due to the laminated structure, compared with a single-layer tubing, E-WBT-UV is superior in flexibility. This improves your work efficiency.
- Plasticizer-Free...E-WBT-UV does not contain plasticizer at all, so you do not have to worry about the elution to the ink.
- Non-PVC...E-WBT-UV is made of non-PVC material.
Certificates and Regulations
- RoHS Compliant...E-WBT-UV is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-WBT-UV does not contain RoHS 10 restricted substances or it does not exceed the upper threshold of RoHS 10 restricted substances.) Certificate is available on request.
- EU REACH and UK REACH...E-WBT-UV is compliant with REACH SVHC 23rd list (209 substances). Certificate is available on request.
- Non-Use of UV-328...E-WBT-UV does not contain UV-328. Certificate is available on request.

What is a Barrier Tube? Reasons for the Need for Tubes with Excellent Oxygen Barrier
If the oxygen barrier or water vapor barrier is low for the ink supply tube, oxygen and water vapor in the atmosphere permeate into the ink.
This leads to the clogging of print head or ink discharge defect due to the generation of air bubble.
Also, if the low oxygen barrier or water vapor barrier tube is used, solvent components of the ink inside the tube will evaporate, changing the ink quality. Printing quality badly affects.
This HAKKO five-layer product includes the barrier resin (middle layer), keeping the oxygen less likely to be permeated.
Cautions:
- E-WBT-UV is a product intended for supplying inks. In case you use other than inks, please contact HAKKO CORPORATION in advance. The tubing performance may be reduced by applying the secondary processing to use conditions, environment, fluid, and customer. We kindly ask you to evaluate the suitability in real settings.
- The material of the middle layer and outer layer is inferior in chemical resistance to the inner layer. Do not allow chemicals to adhere to the tube during immersion or fitting insertion as it may cause swelling and cracking of the tube.
- When using the metal fittings, do not use any scratches or rusty fittings on the nipple surface. Damage to the inside of the tube may cause tube rupture or leakage. Also, do not use resin fittings with scratches on the surface of nipples. Depending on the state of the junction (parting line) of the resin joint, fluid may leak. Please confirm the matching between E-WBT-UV tubing and the fittings. If you need our technical support in fittings, please fill out this form.
- Due to the laminated structure tubing, please use the joints to seal an inner surface of the tubing.
- Please do not use the joints to seal an outer surface of the tubing. This may result in the bursting or coming off from the tubing.
- When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" is also available at the product specifications of E-WBT-UV, which can be downloadable from here.)
- In terms of chemical resistance, please refer to "Chemical Resistance Data."
Technical Information
(A) Slide Curvature Test (5 million times)
(B) UV Penetration Data
(C) Gas Barrier Test Data
1. Gas Barrier Test
Seal the de-gas water into the tubing. Then, leave the tubing under the conditions of temperature (20 $^\circ$C [68 F]) and humidity (50%) for 24 hours. Then, check the increasing amount of dissolved oxygen for each tubing.
2. Sample
Olefin-Based (for Water-Based Ink) Tubing
- E-WBT-4 $\times$ 6-UV Barrier Tubing Black for Water-Based Ink
- E-KYT-4 $\times$ 6 KY TUBE
- Polyethylene Tube 4mm $\times$ 6mm
3. Results
Result: E-WBT-UV is better than E-KYT and polyethylene tube in terms of gas barrier property.
(D) Flexibility Test Data
1. Test Methods
2. Results
Compared with tubes manufactured by other corporations, HAKKO tubes show higher bending stress and smaller amount of deflection, enabling space-saving installation.
Result: E-WBT-UV is better than polyethylene tube in terms of flexibility.
