Pressboard®
Product description
Pressboard® is a paperboard made from multiple layers (or plies) of cellulose-based paper compressed using a combination of heat and pressure to form a dense, rigid material.
Pressboard® is used as electrical insulation in applications such as high voltage transformers, winding, etc.
To provide the widest range of solutions, we can convert transformerboard (coating), cut it to the desired shape, provide various ranges of density and thickness.
Technical properties
- Electrical insulator
- High mechanical resistance
- High purity
