Durable and Diverse Features of Large Diameter Polyimide Tubing
Because polyimide tubing is a thermoset polymer, it cannot be re-flowed or melted. Thermoset materials are typically durable materials due to their strong covalent chemical bonds that hold the structural units together on the molecular level. This means that polyimide tubing, among its other impressive characteristics, cannot be melted. That’s a preferential property for large diameter polyimide tubing that is used so often in such a wide range of applications—from medical devices and industrial applications to the electrical and aerospace industries. Polyimide tubing is chosen across various industries for its many other properties, because it also offers superior thermal resistance, high voltage resistance, chemical corrosion resistance, along with other capabilities like outgassing, anti-nuclear radiation, and optimal flexibility.
The large diameter polyimide tubing that American Durafilm® provides, = / > 0.090” ID, can be produced with tight tolerances, thin or thick walls, and very low concentricity ratios to make it an excellent choice for a wide range of applications. Low concentricity ratios and consistent tight dimensions virtually eliminate weaknesses in the tubing. These key attributes improve the tubes’ performance in demanding applications. Large diameter tubing can be trimmed to very short lengths or laser machined with holes and unique features. It’s so versatile, ask about adding thermoplastic jackets and tips for medical applications and specially formulated coatings to provide release properties at high temperatures and to bleed static charge.
