Highest Heat Resistance
Kept in contact with 300°C flame for one minute, Furukawa Polyimide Tubing on the left shows no change, while Fluorine resin tubing on the right begins to soften.
| FURUKAWA POLYIMIDE TUBING | Fluorine resin tubing | Spiral tubing |
|---|---|---|
| No degradation occurs at 220°C in continuous service or at 400°C in a brief moment. Safety can hardly be threatened, owing to its flameless self-flame extinction without any poisonous fume. |
starts to decompose at about 200°C, softening at high temperature to emit a fluorine gas. | susceptible to glue. |
Seamless
Spiral tubing loosens in contact with 300°C flame, the same can never occur in Furukawa Polyimide Tubing (seamless and unitary forming).

| possesses superlative heat resistance, owing to its seamless unitary forming. | vitally susceptible to glue. |
Thinner Wall Thickness
Comparison of space factor (left: polyimide tubing, right: Fluorine resin tubing - each shows 15 pieces of 1.0mm inside diameter )
Polyimide tubing has the superior space factor compared to Fluorine resin for 3 times.
| FURUKAWA POLYIMIDE TUBING | Fluorine resin tubing | Spiral tubing |
|---|---|---|
| A minimum inside diameter of 0.08 mm is available ; and wall thickness of 0.013 mm is producible, on account of its high tensile strength. Compact, delicate wiring in electronic or other instruments can be laid out, without any concern over space. | unable to support a thickness of less than 0.2 mm or an inside diameter of less than 1 mm, extremely pliable and easy to fade away under tension. | unable to be made with an inside diameter of less than 0.4 mm. |
Good Chemical & Radiation Resistance
Fluorine resin is unlikely to be glued, polyimide is compatible with most types of glue.
| FURUKAWA POLYIMIDE TUBING | Fluorine resin tubing | Spiral tubing |
|---|---|---|
| Polyimide resin is outstanding in adhesion and remains unaffected in chemicals (except alkalis) or radiation. Consequently, new utilities can be offered in chemical or nuclear plant. | incompatible with any glue, falling into decay in radiation. | resistance to chemicals or radiation within limits of glue. |
Good Flexibility
The cross section of a Furukawa Polyimide Tubing, shows a multi-layered structure -- the key to bending endurance.
| FURUKAWA POLYIMIDE TUBING | Fluorine resin tubing | Spiral tubing |
|---|---|---|
| The elaborate layered structure, as shown in the microphotograph, guards against deterioration through shock forces, repeated bending or if used to form a moving part. | surface threatening to separate in parts as shocked. | glued overlap likely to loosen. |
Easy Installation
Upper Fluorine resin tubing is less rigid, even harder to pass a conductor through.
| FURUKAWA POLYIMIDE TUBING | Fluorine resin tubing | Spiral tubing |
|---|---|---|
| Unitary polyimide tubing, being drag free and fairly rigid, allows easy feeding of wire through the inside. Moreover, soldering work is easy, facilitating volume production through outstanding thermal resistance. | slightly greater in friction and rather thick in tubing wall. | glued overlapped surface likely to be clogged. |
