polyimide structure

Polyimides (PI) are high-performance polymers of imide monomers which contain two acyl groups (C=O) bonded to nitrogen (N). These polymers are known for their high temperature performance in the 400-500°C range as well as chemical resistance.

Is polyimide a dielectric?

Polyimides (PI's) have been widely used as dielectric and packaging materials in the microelectronics industry because of their unique physicochemical properties: excellent thermal stability, good radiation and chemical resistance, good mechanical strength, low moisture adsorption, and good adhesion to semiconductor ...

What is the difference between polyamide and polyimide?

The main difference between Polyimide and Polyamide is that the Polyimide is a polymer of imide monomers and Polyamide is a macromolecule with repeating units linked by amide bonds. Polyimide (sometimes abbreviated PI) is a polymer of imide monomers. ... Polyamides occur both naturally and artificially.

Is polyimide an insulator?

Insulation and passivation films

Polyimide materials are lightweight, flexible, resistant to heat and chemicals. Therefore, they are used in the electronics industry for flexible cables and as an insulating film on magnet wire.

How is polyimide film made?

Polyimide film, the generic name of of DuPont's tradename Kapton®, is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imine treatment at high temperature. ... It performs well in a wide range of temperatures as low as ‑452°F (-269°C) and as high as +500°F(+260°).

Is Kapton conductive?

DuPont™ Kapton® RS is an electrically conductive polyimide film developed for heating applications where a thin, lightweight, uniform heater is needed. ... Due to its polyimide composition, it is resilient to high temperatures, thin, and highly flexible.

Is polyimide a thermoplastic?

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.

Is Kapton a polyimide?

In applications where superior adhesion and low shrinkage are important, Kapton® FPC is the polyimide film of choice. Kapton® FPC meets IPC 4202/1 requirements. DuPont ™ Kapton® HN general-purpose film has been used successfully in applications at temperatures as low as -269°C (-452°F) and as high as 400°C (752°F).

What are the typical sizes in polyimide sintering?

fairly narrow size distribution (the main fraction lies in the range of 6-15 μm).

Where is polyamide used?

Synthetic polyamides are commonly used in textiles, automotive industry, carpets, kitchen utensils and sportswear due to their high durability and strength. The transportation manufacturing industry is the major consumer, accounting for 35% of polyamide (PA) consumption.

Can I use electrical tape instead of Kapton tape?

A better tape for electronics. ... Kapton tape (generically known as polyimide tape) is a cool tool in these cases and better than regular black electrical tape for a number of reasons: It is heat resistant. You can put a soldering iron on Kapton tape and it will not melt.

What is polyimide tape used for?

Thin, conformable tapes, provide electrical insulation, chemical and high temperature resistance. Polyimide tapes consist of an amber colored polyimide film coated with a pressure sensitive silicone adhesive. They are often used in applications that require good chemical resistance or high temperature resistance.

Is Kapton tape an insulator?

The tape is flame-resistant and can be used as electrical and thermal insulation. ... Kapton^® tape is commonly used as a wire and cable wrap as well as to protect electrical components during soldering.
