(A) Gas Barrier 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 Barrier Tubing for Water-Based Ink
  • E-KYT-4 $\times$ 6
  • Polyethylene Tube 4mm $\times$ 6mm
Fluorine-Based (for Solvent-Based Ink) Tubing

  • E-SBT-4 $\times$ 6 Barrier Tubing for Solvent-Based Ink
  • E-SJ-4 $\times$ 6
  • E-PD-4 $\times$ 6
  • Fluorine Rubber Tubing

(B) Ink Barrier Test Data

1. Solvent Barrier Test

Seal the ink into the tubing. Then, leave the tubing under the condition of temperature (50 $^\circ$C) with sealing both ends. Then, measure the weight (weight changes) of the ink tubing in 3 days.
* Except the weights of tubing and sealing items, we only measured the weight changes of the solvents.

2. Sample

  • Barrier Tubing for Solvent-Based Ink E-SBT
  • Barrier Tubing for Wate-Based Ink E-WBT
  • Flexible Fluorine (ETFE) Resin Tubing E-SJ
  • Polyethylene Tube (Tube Commercially available)
  • Soft Olefin Tube (Tube
    Commercially available)
    * All tubing Sizes: I.D. 4.0mm $\times$ O.D. 6.0mm

(C) Solvent Barrier Test Data

1. Solvent Barrier Test

Seal the solvent (Diethylene Glycol Diethyl Ether) in the tubing.
Then, leave the tubing under the condition of temperature (60 $^\circ$C) with sealing both ends.
Measure the weight (weight changes) of the ink tubing in 7 and 14 days.
* Except the weights of tubing and sealing items, we only measured the weight changes of the solvents.

2. Sample

  • E-SBT-4 $\times$ 6
  • E-SJ-4 $\times$ 6
  • Fluorine Rubber Tubing

3. Results
