| Product Model | Polyimide Tubing |
Polymide Tubing is one of the materials under NASA’s space development program. It was originally used in space shuttles, military aircraft and other molded products. It has been applied in various fields and has the following advantages.
Tube is formed in one piece and the general spiral type is different from heating with no peeling phenomenon.
Thickness
It can be produced with an inner diameter of 0.127mm and a pipe wall of 0.025mm.
Special multiple structure, impact resistance, and bending resistance with no peeling or damage.
Various adhesives can be used, including alkaline and radioactive drugs. It is non-toxic, non-polluting and not harmful to the human body.
Convenient work
The pipe wall is solid and can be carried out smoothly during the casing operation, and the soldering operation can be carried out directly due to the heat resistance.
Cold and heat resistance
Withstanding temperature -269℃～+400℃
