Author Archives: Better Densifiers

Expanded Polystyrene, widely known as Styrofoam (Dow Chemical’s trademarked EPS foam product) is commonly used for packaging consumer products, to-go restaurant containers, fish boxes, insulation panels, etc.

Hot melt densifiers are top fed via a hopper style infeed. Loose foam is dropped into the hopper where it goes through a shredding process. The shredded foam then drops down onto an auger which shuttles it into a melt unit.

Styrofoam is pervasive in our society. It is a great packaging material and insulator because it is very light, durable, moldable into almost any shape, and cheap to produce. “Styrofoam” is a trademarked (Dow Chemical Corporation) thermal insulation made from polystyrene.
