What Is EPS?

EPS stands for expanded polystyrene, which is a rigid, lightweight material with a closed-cell structure. You may often hear of expanded polystyrene being referred to as “styrofoam.” However, styrofoam is actually a trademarked brand for extruded polystyrene (XPS). You have most likely seen EPS when getting a coffee, takeout, or meat from the grocery store (foam cups, takeout containers, meat packaging).

Manufacturing Process:

Raw beads are expanded by using steam and pressure to create pre buff beads of various densities, which are stored in silo bags before being transferred to our molding machine which again uses steam and pressure to then form a block. The blocks created in the molding machine at Insulation Technology Inc are 2′ x 4′ x 16′. These blocks (billets) are stored on the floor in our warehouse where they age before being custom cut for various applications. Our aged material is stored on the floor for a minimum of six weeks, whereas our non-aged material only sits for a minimum of two to three days. 

The sizes and densities InsulTech offers:

Thickness: 1/4″ to 25″

Lengths: Up to 192″ (16′)

Widths: Up to 48″ or (4′)

Densities: 1.0lb, 1.25lb, 1.50lb, 2lb per cubic foot
