Black Kapton® Type MTB provides thermal conductivity that is higher than Kapton® HN. The film's thermal radiation properties make it ideal for uses requiring thermal energy transfer such as loudspeaker voice coils and electrical insulating pads.General Kapton® information: Kapton® is synthesized by polymerizing an aromatic dianhydride with an aromatic diamine. It has excellent chemical resistance; there are no known organic solvents for the film. It does not melt. It can be used at both high and low temperature extremes. Kapton® polyimide films can be used in a variety of electrical and electronic uses: wire and cable tapes, formed coil insulation, substrates for printed circuit boards, motor slot liners, magnet wire insulation, transformer and capacitor insulation, magnetic and pressure-sensitive tapes, and tubing.Data provided by DuPont High Performance Films.No detailed property information is available about this grade. Other Kapton® grades in MatWeb such as Types HN and VN have more details.
