Cotton phenolic sheets – HGW 2082

These sheets (rods, tubes) are made from cotton fabric as fortifier material and cresolformaldehyde resin as a bond.

Used electric motor intermediate bearings, plates or other components that are exposed to electrical and mechanical stresses and friction production. 
Resistant to weak acids rather high temperatures. This material has good mechanical and antifriction properties.

Plate dimensions: 1020x2040 mm, 1220x2440 mm and etc.
Thickness: 0,5 mm - 100 mm
