The effect of crosslinking on properties of low-density polyethylene filled with organic filler

Scanning electron microscopy was employed to investigate the effect of peroxide-initiated crosslinking on behaviour of composites of low-density polyethylene filled with wood flour. The improved wetting of the filler by the matrix and/or the increase in the matrix/filler adhesion was shown to be the main consequence of crosslinking, with the obvious influence on the physical, especially mechanical properties.
