How are Kapton heaters made?
Polyimide (Kapton) heaters make use of very thin (e.g. 50μm) etched metal (usually nickel based alloy) foil as resistance element. The resistance pattern to be etched is designed in CAD and transferred to the foil, which is then processed through acid spray to produce the desired resistance pattern.
How are polyimide heaters made?
Polyimide heaters are constructed of an etched foil element of 0.0005” or 0.0001” thickness, which is encapsulated between two layers of polyimide film and 0.001” FEP adhesive. These flexible heaters are available in a variety of shapes, sizes, and wattages.
Is Kapton the same as polyimide?
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.
How hot can Kapton get?
Kapton® HN has been used successfully in applications at temperatures as low as -269°C (-452°F) and as high as 400°C (752°F). Kapton® HN film can be laminated, metallized, punched, formed or adhesive coated.
Is polyimide a plastic?
Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles.
How is Kapton flexible?
Due to its polyimide composition, it is resilient to high temperatures, thin, and highly flexible. The resistive property is inherent to the film, so it cannot be cracked, rubbed off or otherwise easily damaged.
Is polyimide a good insulator?
Polyimides are particularly interesting for microelectronics as well as for high voltage electrical engineering industry, thanks to their high thermal stability, high glass transition temperature, low dielectric constant, and overall very good electrical insulation properties (high breakdown field, low dielectric loss …
Does Kapton tape insulate heat?
This high-temperature tape is made from Kapton®† film and a cross-linked silicon adhesive. The tape is flame-resistant and can be used as electrical and thermal insulation.
What temperature can polyimide withstand?
Kapton® Type HN, all-polyimide film, has been used successfully in applications at temperatures as low as -269°C (-452°F) and as high as 400°C (752°F).
Is Kapton a good thermal insulator?
Kapton® MT+ offers the highest thermal conductivity of any polyimide film on the market and offers excellent breakdown voltage, mechanical resilience, and flexibility to make it an ideal substrate to incorporate into an electrically isolating thermal solution for your electronic or automotive application.
What is polyimide film used for?
In addition to excellent heat resistance properties, polyimide film also has excellent dielectric properties. Typical applications for polyimide film include multi-layer insulation blankets for space, flexible electronics, tapes, and various other high heat applications.
Is Kapton flammable?
Kapton® is self extinguishing as it has the highest UL-94 flammability rating: V-0. The outstanding properties of Kapton® permit it to be used at both high and low temperature extremes where other organic polymeric materials would not be functional.
Is Kapton electrically conductive?
DuPont™ Kapton® RS is an electrically conductive polyimide film developed for heating applications where a thin, lightweight, uniform heater is needed.
What is polyimide thermal conductivity?
The thermal conductivity of the PI/BN composite was up to 1.2 W/m-k, for a mixture containing 30 wt % of micro and nanosized BN fillers in the polyimide matrix. The PI/BN composites had excellent thermal properties.
What temp does Kapton tape melt?
It has no melting point and can be used over a temperature range of -269°C to 350°C. It can be used constantly at a temperature of 240°C.
Is Kapton tape an electrical insulator?
Kapton is a polyimide film from DuPont with a strong balance of electrical, chemical, mechanical, physical, and thermal properties. Unlike other electrical insulators, Kapton has good dielectric strength even at high temperatures. Desirable over a wide temperature range, Kapton film can also withstand low temperatures.
Why do polyimides have high melting temperatures?
The strong polymer chain interactions give polyimides very high glass transition temperatures, many extending beyond 300 °C (572 °F) and some as high as 400 °C (752 °F).
Can you melt Kapton?
