These proven electrical insulation materials feature the right balance of properties, enabling them to deliver reliable performance even in the most demanding environments.
When you’re designing products that require electrical insulation systems (EIS), DuPont can make your job easier in meeting electrical insulation standards. That’s because we provide the industry’s broadest offering of pre-approved systems, over 400, by Underwriters Laboratories (UL) and recognized to IEC standards. These systems include a wide range of DuPont materials used in electrical insulation, including: films, aramid papers, pressboard products, and thermoplastic resins. Our portfolio of high-performance materials enable us to meet virtually all the electrical insulation requirements of today's transformers, motors, relays, switches, sensors and encapsulated coils and components.
Family of heat sealable fluoropolymer coated polyimide materials that are designed specifically to meet the demands of the aerospace and cable industry.
Maintains its unique combination of mechanical properties under the harshest of conditions.
DuPont™ Kapton® corona resistant film is a state of the art polyimide film that withstands the damaging effects of corona discharge. The corona resistance of Kapton® 100CRC film provides improved service life and operational efficiencies beyond that of conventional insulation materials. In addition to the corona resistant properties, Kapton® CRC offers excellent, physical, electrical, thermal, and chemical resistant characteristics expected with Kapton® polyimide films.
Kapton® CRC polyimide film has been developed for use as an electrically insulating material for high voltage environments where the potential for corona discharge is present. Kapton® CRC is typically used in industrial motor and generator applications as magnet wire, turn to turn strand, coil, slot liner and ground insulation materials. It has also been used to form laminates with other materials, such as DuPont™ Nomex® paper or mica insulations, to provide a tailored electrical insulation property.
Combines the corona resistant polyimide film with a heat fusible FEP fluoropolymer film.
General purpose HN film coated or laminated on one or both sides with a FEP fluoropolymer.
DuPont™ Kapton® 150FWN019 is a two-layer, polyimide, FEP fluoropolymer dispersion-coated heat-fusible composite film with a unique balance of excellent physical, electrical, thermal durability and chemical resistance properties. 150FWN019 has superior scrape abrasion resistance and motor manuacturers have reported that wire insulated with 150FWN019 exhibits lower frictional properties than wire insulated with other commonly used polyimide materials. 150FWN019 is ideal for demanding magnet wire applications. and for difficult-to-wind motors.
Kapton® 150FWR019 film is constructed of a 1.0 mil Kapton® polyimide film with 0.5 mil of FEP fluoropolymer on one side.
Recommended for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.
Recommended in applications where low shrinkage and superior adhesion are important.
The properties of DuPont™ Kapton® 150PRN411 make it suitable for insulating copper conductor used in high temperature magnet wire applications where improved adhesion between layers and abrasion resistance are desired. Kapton® 150PRN411 polyimide film consists of a layer of 25 micron thick Kapton® HN polyimide film between two layers of high melt temperature fluoropolymer. One of the fluoropolymer layers is approximately ten microns thick and the second layer is approximately three microns thick.
Kapton® type XP provides a type H film coated on one or both sides with a proprietary fluorocarbon resin which provides excellent mechanical strength and adhesive properties at elevated temperatures. In addition, high level bond strengths of XP to copper, itself or other materials are maintained at elevated temperatures. The four graphs included with this bulletin compare retention of bond strength of type FN and type XP from room temperature to 200°C. Kapton® XP exhibits the same chemical stability, electrical properties, and mechanical strengths in high and low temperature environments as has been demonstrated with Kapton® FN.
Availability Both 2 mil Kapton® XP (919) and 1.5 mil XP (019) are in inventory. Other constructions can be made available as market applications and needs develop. Substrate preparation and electrical, mechanical and chemical data can be found in the Kapton® Summary of Properties booklet (EI-10142).
