FILM INSULATION SYSTEMS
DuPont is offering more ways to engineer electrical devices for fast-track recognition for Class N (200° C) or Class H (180°C) performance under the UL(r) 1446 standard. Kaladex(r) PEN is a biaxially oriented film with performance and cost between those of PET polyester and polyimide films. Kaladex(r) offers high stiffness and mechanical strength, low thermal shrinkage, excellent dielectric strength, and excellent hydrolysis and chemical resistance. DuPont supplies it in a range of thicknesses from 100 to 500 gauge (25 to 125 um). With the new systems, a total of five EISs using Kaladex(r) 2000 film are now available, two with Class H and three with Class N recognition under UL 1446 and IEC publication 85. Other insulation materials listed in the systems include DuPont Kapton(r) brand polyimide film, DuPont Nomex(r) brand aramid paper and parts molded from DuPont Rynite(r) brand PET thermoplastic polyester resin.
