(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

3. Results

(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

3. Results

(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

(D-2) Slide Curvature Test Data Part II

Sample A (Flexible Fluorine (ETFE) Resin Tubing; I.D. 4 mm $\times$ O.D. 6 mm) and Sample B (Olefin Tube manufactured by other companies; I.D. 4 mm $\times$ O.D. 6 mm) are installed under the slide curvature test machine. In a state where the bending radius is 50 mm, the sample conditions (1 million times after the friction between the tubes and the cable tube when the continuous slide bending is performed) are measured.

Test Device:Slide Curvature Test Machine (Pictures Shown Below)

  • Bending Radius: R = 100
    (Inside Energy Chain)
  • Test Machine Velocity:810mm/sec
  • Number of Attempts:1 Million Times
  • Test Temperature:Room Temperature (20 – 30 $^\circ$C)

Shaving-Results

The photographs above are the samples after the slide curvature test for 1 million times. As shown in the photographs above, it was confirmed that Sample B was shaved deeper than Sample A. In the most scraped portion (thickness), Sample B was scraped more than 2 times as much as Sample A.

(D-3) Slide Curvature Test Data Part III

Sample A (PFA Tubing: I.D. 4mm $\times$ O.D. 6mm; manufactured by other companies), Sample B (Flexible Fluorine (ETFE) Resin Tubing Black: E-SJ-4$\times$6-BK) and Sample C (Flexible Fluorine (ETFE) Resin Tubing Black (Ultra Soft): E-SJUS-4$\times$6-BK) are installed under the slide curvature test machine. In a state where the bending radius is 50 mm, the sample conditions (5 million times after the friction between the tubes and the cable tube when the continuous slide bending is performed) are measured.

  • Bending Radius: R = 50
    (Inside Energy Chain)
  • Test Machine Velocity:810mm/sec
  • Number of Attempts:5 Million Times
  • Test Temperature:Room Temperature (20 – 30 $^\circ$C)

Results

The photographs above are the samples after the slide curvature test for 5 million times. As shown in the photographs above, it was confirmed that Sample A was shaved deeper than Sample B and Sample C.

(E) Flexibility Test Data

1. Test Methods

FlexibilityTest-TestMethods

2. Results

Compared with tubes manufactured by other corporations, HAKKO tubes show higher bending stress and larger amount of deflection, enabling space-saving installation.

*Please note that in terms of bending stress value, “smaller bending stress value” means “more softness.”

(F) Ultraviolet Penetration Test Data

1. Ultraviolet Penetration Data
