Technical laminates - sheets
COTTON PHENOLIC SHEET – Hgw 2082
These sheets are made from cotton fabric as fortifier material and cresolformaldehyde resin as a bond. This material has good mechanical and antifriction properties enable this material to be used for production of bearings, geared wheels, garnishing of antifriction parts of presses, heavy planing machines, frame saws. Thanks to its good resistance against weak acids at elevated temperatures, it can be used as construction material for machines and devices production rayon, galvanic plating etc.
Available dimensions: 1050x1050 mm, 1050x2050 mm, 1050x2350.
Available thickness: 0,5 mm - 100 mm
