Product architecture
Built around the materials buyers ask for most.
Clear entrances for core motor insulation, lead protection, high-voltage/high-temperature products and add-on fixing parts.
NMN
F class motor slot and phase insulation with better heat resistance than DMD.
NHN
H class motor slot and phase insulation for higher-end motor systems.
Nomex Paper
F/H class motor slot insulation and transformer barriers with high tear strength.
PI Film / Kapton
Ultra-thin, high-temperature insulation for advanced motors, aerospace and demanding systems.
Heat Shrink Tubing
Single wall, dual wall adhesive and fluoroplastic tubing for sealing, lead protection and harnesses.
Mica Products
Mica tape, mica sheet, mica board and mica paper for high-voltage and high-temperature applications.
3240 / Slot Wedges
Epoxy glass rods, tubes, washers, slot wedges, cable ties and clamps for insulation support.
