Technical laminates - sheets

COTTON PHENOLIC SHEET – Hgw 2082.5

Attention: open in a new window.

These sheets are made from cotton fabric as fortifier material and cresolformaldehyde resin as a bond. This material has excellent mechanical and antifriction properties and good polishability. It´s suitable for the manufacturing of parts exposed to mechanical and electrical stresses.

Available dimesnions: 1050x1050 mm, 1050x2050 mm.
Available thickness: 0,5 mm až 100 mm, jiné po dohodě s výrobcem.
