Hard paper, layers of brown paper, soaked phenol resin and then compressed

Hard paper is composed of layers of brown paper, which has been soaked in a phenol resin and then compressed at a high temperature.
It is used on a large scale in the electrical industry.

The great advantage of hard paper, apart from the electrical resistance, is the low price. It has no processing range and bends minimally on heating, so that short-circuiting is avoided.

Available as pipe, rod and plate in various sizes or modified to product.
