cellulose based insulation papers


Insulation class A (105 °C)

For many decades, presspaper has demonstrated its value as an insulation class A material. It is made of cellulose fibers and is obtained from a paper manufacturing process without the use of binders.


A proven surface insulation material, Presspahn is resistant to high voltage and a high capacity for impregnation with transformer oil (dielectric mix of oil-cellulose).


This press paper and pressboard is available in a variety of different thicknesses and formats, and can withstand high heat loads for short periods of time.


Presspahn is produced from 100% electrical grade kraft wood pulp and is a designed as a surface insulation material on cellulose for insulation class A.


It can be punched, folded, cut and, in some cases, shaped as well.


Depending on the type of cellulose, fibre conditioning and machinery settings, UKi supply a variety of presspaper and pressboard types with very specific characteristics.


Presspahn coil is available in thicknesses from 0.13mm to 1mm thick and also in rigid board from 0.5mm to 12mm.
