"MIKI" INSULATION PAPERS
"MIKI" insulation papers (pressboard class 2, Coil Insulating paper Class 2 & LD-Board) are high grade insulation material with 100% imported kraft wood pulp usedfor wide insulation field.
Main Types:
Pressboard Class 2(PB-2): principal Applications: Electirc motors, transformers, ringsflanges, spacers, gaskets, capacitors, etc, Available colors are brown, red, green.
Coil Insulating Paper Class 2(PI-2): Principal applications: Speaker coil paper, cableraping, capacitors, etc.
LD-Board: This is a Non-pressed low density frbre paper. It is used when high densityis not required.
Other insulation papers include "BASE DDP", wrinkling coil paper for transformers and"Senkaski" paper for Speaker coil.
