Product Description

Description
Insulation Pressboard is a special product based on pure cellulose taken from long-fibred coniferous wood. This is structured into a fibrous tissue without additional adhesive and then pressed. Due to its high chemical purity, pressboard is excellently suited as an insulation material in electric machines, capacitors and oil-filled transformers. 100% wood or cotton thick board is characterized by its high density.
