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.


Application
Presspaper is used for electrical industrial board for motors, electric device, instruments, swith board, transformer for insulation and assembly pieces under 35kv. 100% wood or cotton thick board is characterized by its high density.
Good mechanical strength, low compression and high electric strength
Size: 0.8-4mmx1mx2m
Color: Brown, red
Package: Pallet
