Pressboard is a cardboard pressed with 100% pure cellulose.
Manufactured exclusively with cellulosic fibers, without any use of glues, fillers or colours, on special machines for cartons which allow to couple in the wet state, without the use of glues, different layers of elementary mix, previously refined and purified, using the most modern equipment used in the paper industry.
Light hazelnut in colour, Presspaper is used in the construction of transformers, capacitors, switches and other electrical devices both in oil and in air.
It can also be supplied in sheets, ideal in the transformer industry, for making insulating cylinders, flanges, barriers and spacers.
It is particularly suitable for all applications which require an insulator with excellent heat stability, high chemical purity and high mechanical and electrical resistance.
