FOREX®-CLASSIC
is a slightly expanded, closed-cell rigid pastic sheet material with a
particularly fine and homogeneous cell structure and a silky matt surface.
FOREX®-CLASSIC is the lightest sheet material of its kind but has high
inherent rigidity and remains stable even after intensive processing.
