There are two common expended foam, one is EPE, the other is EPS. Foam expending machines fills air to Polythene and Polystyrene, which makes these materials become soft, light, adiabatic. Expended foams are widely used from package to food container. However, it’s a big challenge to recycle them. Air is the biggest problem. In order to remove air from foams, Genius EPE EPS Foam Recycling Machine equips cutter compactor. It breaks and heats foams before extruding them. This construction releases air in foams and creates higher productivity.
