WebProperties. EPE foams are low density, semi-rigid, ... Consumption of polyethylene for PE foam was estimated at 114x10 6 kg in 2001. The majority was used for non-crosslinked foams, but crosslinked PE foams represented a significant (~ one third) fraction of demand. Use in protective packaging represented the largest use sector for such foams.
