Expancel for high bulk in core board and card board

Expancel Microspheres is used in board applications where a high bulk is needed. Expancel will improve bulk and bending stiffness of the board, 1% of Expancel can increase the bulk with up to 25%.

These effects are achieved when Expancel Slurry, added in the wet-end of the board machine, expands in the drying section, giving an increased bulk of the board.

Expancel Slurry can also be coated with a binder on the surface of board or paper to provide anti-slip properties.
