All Electrical Insulators

Materials Direct offers one of the highest quality and most diverse ranges of Electrical Insulator materials in the world

  • All
  • High Voltage
  • Thermally Conductive

DuPont™ Kapton® MT – A1

  • 3x the thermal conductivity and cut through strength of standard Kapton® HN.
  • Excellent breakdown voltage, mechanical resilience, and flexibility
  • MT has higher modulus than HN; this offers improved strength to the final product.

DuPont™ NOMEX® NKN 5-2-5

  • Excellent for high-temperature applications
  • Will not delaminate or blister at high temperatures
  • High dielectric strength

DuPont™ Kapton® 100HN

  • All purpose – can be laminated, diecut, slit, formed, or adhesive-coated.
  • 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.

DuPont™ NOMEX® 410

  • Exceptional thermal stability
  • Outstanding mechanical toughness
  • Inherent dielectric strength

DuPont™ MYLAR® A

  • Balanced tensile properties
  • Excellent resistance to moisture and most chemicals
  • Can withstand temperature extremes from -100°F to 300ºF
