Thank you! Extruded polystyrene — XPS has the same chemical composition as the expanded polystyrene EPS , but is made by a different technology; as a result, the produced foam has smaller air pockets and is more uniform.

It often comes in pink, blue, green, etc. XPS styrofoam is ideal for manufacturing demonstration panels and in construction area. A resilient and robust construction material boasting a high compressive strength and a superior thermal performance, Extruded polystyrene is the number one choice for home builders, specifiers, architects and engineers.

The high-density cell structure of XPS styrofoam also makes it practically impervious to water. There are several reasons why the abovementioned materials are so widely used wiki. Machines T — Series! Machines MW — Series! Polystyrene as a versatile material Different uses of polystyrene. EPS is available in several compressive strengths to withstand load and back-fill forces.

This closed-cell structure provides minimal water absorption and low vapor permanence. Commonly used as insulation for walls, foundations and roofing, there are many benefits to selecting EPS products :. Raw beads are expanded using steam, creating pre puff beads, which are then cured in large bags before being conveyed to the mold. The blocks are then placed on the storage floor to age for the appropriate length of time before being cut into various shapes and sizes.

Blocks are produced in several densities to meet specific project needs. Although ICA does not stock any cut foam, regularly cut sizes are: 48 inches by 96 inches and 24 inches by 96 inches. Almost any size is available as a custom order. Density is a measure of mass per volume.
