What is polyimide tubing?
Polyimide is a polymer thermoset plastic that has exceptional thermal stability, chemical resistance, and tensile strength. These characteristics make polyimide an ideal material for high-performance medical applications. The tubing is lightweight, flexible, and resistant to heat and chemical interaction.
Can you extrude polyimide?
Duke Extrusion can provide polyimide tubing that is custom tailored to the unique needs of your application. Our polyimide medical tubing is commonly used in high-pressure applications, such as inflation lines for balloon catheters.
How is polyimide tubing made?
Myth 1: Polyimide tubing is difficult to bond Polyimide tubing is constructed in many layers on a mandrel; the process is known as “dipping” or “dip dispersion” in which each layer is applied and cured until the desired thickness is achieved. Each layer of the tube is extremely thin: in the order of 0.00010–0.00012 in.
Can polyimide be injection molded?
Polyimide is a popular plastic material that can be injection molded to obtain certain shaped products. Polyimide injection molding is to inject the molten polyimide into specific mold with injection molding machine, the basic processing is going through injection molding, stamping, compaction, and cooling.
Is polyimide thermoset or thermoplastic?
thermoset polymer
The Polyimide Forming Process and Characteristics Because polyimide is a thermoset polymer it cannot be re-melted like thermoplastic, and is cured using heat, a chemical reaction, or irradiation as the driving energy force. Before curing, thermoset materials exist in a liquid or malleable form.
Is polyimide the same as Kapton?
Since Kapton tape is a type of polyimide tape, all the same things that make polyimide tape special make Kapton tape special. It’s heat and chemical resistant, it’s strong, and it’s available in very thin sheets.
