Characteristics

Chemical Resistance...Since the inner layer is made of ETFE fluorine resin, E-SJ-CBU 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, E-SJ-CBU is superior in flexibility. This improves your work efficiency.
Hard to Break...Unlike a single-layer fluorine tubing, E-SJ-CBU is hard 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...E-SJ-CBU does not contain plasticizer (an elution material) at all. E-SJ-CBU is an oil-free tubing.
Non-PVC...E-SJ-CBU is made of a non-PVC material.
Low Elution and Low Odor...Since E-SJ-CBU contains very low levels of elution and odor, it is highly recommended for use in transfers of food, beverage, and cosmetics.
High Purity...Fluorine resin does not contain any additives such as plasticizer, so E-SJ-CBU is suitable for transferring high purity chemical fluids.
Easy to Cut...Since we print the cut mark on the hose every meter, it is easy to cut the length you would like to.
Transparency...E-SJ-CBU enables you to check the fluid very easily.
Original Fittings...By using our original fittings, you can avoid accidents which are caused by incorrect choices of hose and fittings. For more information on our original fittings, please scroll down to the end.

Certificates and Regulations

RoHS Compliant...E-SJ-CBU is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-SJ-CBU 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.
Non-Use of UV-328...E-SJ-CBU does not contain UV-328. Certificate is available on request.
Food Sanitation...E-SJ-CBU conforms to the Food Sanitation Law No.370 (No.370 of the Ministry of Health and Welfare for Food Sanitation). (Conformity to N-Heptane). [Regarding the conformity of “Partial Revision of the Food Sanitation Law” (Effective on June 1, 2020) and Positive List System (PL), please download here.]
Regulation (EC) No 1935/2004 and (EU) No 10/2011...An inner layer of E-SJ-CBU is compliant with (EC) No 1935/2004 and (EU) No 10/2011.

Cautions:

Due to the laminated structure tubing, please use the joints to seal an inner surface of the hose.
Please do not use the joints to seal an outer surface of the hose. This may result in the bursting or coming off from the hose.
When you use our products, please refer to "Precautions for Use."("The Precautions for Use" of E-SJ-CBU is also downloadable here.)
In terms of chemical resistance, please refer to "Chemical Resistance Data."
Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJ-CBU is usable for high purity fluids before you use.
Although the inner layer is resistant to fluids, depending on working environments, the fluids would be permeated through the inner layer, resulting in the danger of swelling and degradation of the middle or outer layer.

Technical Information

(A) Relationship Graph between Working Temperature and Maximum Working Pressure

E-SJ-CBU_Relationship between Working Temperature and Maximum Working Pressure

(B) Flexibility Comparative Data

Test Sample	Minimum Bend Radius	Amount of Deflection (mm)
E-SJ-4$\times$6-CBU	23 (Catalog Value: 25)	31
PTFE Tubing (4$\times$6)	20	7
PFA Tubing (4$\times$6)	23	6

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. The lower the minimum bend radius value is, the harder the hose (tubing) is. Thus, E-SJ-CBU is much flexible than PTFE and PFA tubing.

(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.

(D) Washability Data

Test Conditions	Kind of Ink	Solvent-Based Inks
Washing Methods	Ink Inclusion Period	7 Days (at Room Temperature)
	Cleaning Solution	Ethyl Acetate
	Cleaning Time	20 Seconds
	Pressure	Less than 0.01MPa

Results: In comparison with a Nylon hose, Flexible Fluorine (ETFE) Resin Hose is excellent in non-adhesiveness of the inner layer, so you can reduce washing time and save cleaning solutions and labor costs.
