Flexible Fluorine (ETFE) Resin Tubing (Eco-Friendly Type) [Model Number: E-SJECO]

Flexible Fluorine (ETFE) Resin Tubing (Eco-Friendly Type) [E-SJECO] is a multi-layer fluorine tubing that uses plant-derived raw polyurethane materials (biomass-based polyurethane materials), which reduces petroleum resource-derived plastics by 25%, compared to our standard product of Flexible Fluorine (ETFE) Resin Tubing [E-SJ].

As a manufacturer of plastic tubing and hoses, HAKKO continues to develop environmental-friendly products to contribute to a sustainable world.

Single-layer teflon tubing is hard (stiff) and easy to break. Our Flexible Fluorine (ETFE) Resin Tubing (Eco-Friendly Type) is a sustainable tubing that is alternative for a teflon tubing.

Characteristics

Environment-Friendly Materials...E-SJECO uses plant-derived raw materials (biomass materials) that reduce petroleum resource-derived plastics by 25%. We can issue the certificate upon request.
Chemical Resistance...Since the inner layer is made of ETFE fluorine resin, E-SJECO is resistant to most of the chemical substances.
Flexibility...Due to the laminated structure, compared with a single-layer fluorine tubing, E-SJECO is superior in flexibility. This improves your work efficiency.
Hard to Break...Unlike a single-layer fluorine tubing, E-SJECO 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...E-SJECO does not contain plasticizer (an elution material) at all. E-SJECO is an oil-free tubing.
Low Elution and Low Odor...Since E-SJECO 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 E-SJECO is suitable for transferring high purity chemical fluids.
Transparency...E-SJECO 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-SJECO is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-SJECO 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-SJECO is compliant with REACH SVHC 25th list (219 substances). Certificate is available on request.
Non-Use of UV-328...E-SJECO does not contain UV-328. Certificate is available on request.
TSCA (Toxic Substance Control Act) Compliance...E-SJECO does not use decaBDE, PIP(3:1), 2,4,6-TTBT, PCTP and HCBD. Certificate is available on request.
PFOA and POFS...E-SJECO does not contain perfluorocarboxylic acids (PFCAs C 9 - C 14), their salts or PFCA-related substances. Certificate is available on request.

Cautions:

In case you have to use your fittings other than our original fittings, 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
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-SJECO 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

(B) Minimum Bend Radius, Amount of Deflection and Kink Resistance Data

Test Sample	Minimum Bend Radius (mm)	Amount of Deflection (mm)	Kink Resistance (mm)
E-SJECO-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, E-SJECO is much more flexible than PTFE and PFA tubing.

(D) 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.

(E) 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.

(F) Transparency Comparison Image: E-SJ vs. PTFE Tubing

[Sample] We pour the same yellow paint through both tubings and seal both ends. [Result] As you can see, compared with a PTFE tubing, HAKKO E-SJ is easier to see through.
