Transformerboard (pressboard) fibers

Transformerboard is a cardboard made from several layers (or plies) of cellulose-based paper which is pressed using a combination of heat and pressure to form a dense and rigid board.

Tansformerboard is used as an electrical insulation material for high voltage transformers, windings, etc.

To meet the widest range of customer requirements, we can treat Transformerboard (by applying coatings), cut it to the required shape and provide various densities and thicknesses.

For example: Transformerboard coated with a thermosetting phenolic epoxy coating applied in a diamond pattern (to one or both sides) which offers very high purity and good mechanical strength, providing good compatibility with transformer oils.
