Brief Introduction
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.

Features
Insulation class A (105 °C)
Hot-pressed Pressboard, 100 % sulphate pulp
High hardness and stiffness
Low shrinkage and compatibility
High purity and mechanical strength
Good compatibility with liquid dielectrics
Further processing is ensured since the pressboard can be punched, folded, cut and formed without difficulty.
