The computers we use are typically encased in polystyrene, which is an older polymer. Polyurethane does not melt, unlike polystyrene. However, polyurethane provides higher-quality insulation in many instances. Polystyrene will melt at temperatures in the 200- to 300-degree range. An extremely cost effective packaging material, it is moisture resistant, a good thermal insulator, (insulation R-value of 4.0 per inch) and it is structurally strong (compression strength of 1000 lbs per square foot.) While this can be a difficult decision, the team at Metro Home Insulation & Waterproofing is able to help you with any of your questions! Of the two materials, polyurethane is the better material. R-Value Comparison, Icynene Foam vs Polyurethane Foam. Expanded Polystyrene (EPS) is the generic industry name for the white rigid material made by expanding polystyrene beads with steam and pressure to bond the beads together to form blocks or to shape molds. Polystyrene, for instance, is the material used to make coffee cups for protection in packaging. Additionally, it is moderately soluble in many organic solvents, cyanoacrylate, and the propellants and solvents of spray paint. Rigid foam is primarily installed in unfinished walls, roofs and foundations. Expanded Polystyrene (XPS) Bo Foard of Foard Panel has been in the SIP business for over twenty years. Visco elastic foam is another term for memory foam. The Styrofoam brand polystyrene foam, which is used for craft applications, can be identified by its roughness and the "crunch" it makes when cut. Installing rigid foam reduces thermal bridging, raises the R-value of a wall or roof assembly, and greatly reduces air leaks. There are two types of polystyrene rigid foam insulation: Available in rigid foam boards made from an expansion or extrusion process, polystyrene insulation offers easy on-site installation with only simple tools required to cut it to length or fit it around obstructions. Mudjacking vs. Polyurethane Foam, there’s the big question. This makes spray foam ideal for oddly shaped spaces and filling gaps around floor and wall penetrations. This common ‘expanded polystyrene’ is often shortened to ‘EPS’ whereas styrofoam is officially ‘XPS’ meaning extruded polystyrene. EPS (Expanded Polystyrene) Vs Polyurethane. Expanded Polystyrene (EPS) is the generic industry name for the white rigid material made by expanding polystyrene beads with steam and pressure to bond the beads together to form blocks or to shape molds. Although Icynene foam has lower R-Values than polyurethane foam (less thermal resistance and less insulation capacity), it still has valuable uses for insulation depending on the scenario. Though they are sometime confused, there are differences between the two in terms of their composition, the ability of finished products to resist chemicals and conduct heat and their tolerance for thickness. However, this resistance varies according to the density and thickness of each material. Polystyrene and polyurethane insulation materials sound similar, but they have their differences! Both polystyrene and polyurethane are polymers, synthetic substances made from long chains of molecules. http://www.EPSFoamPro.com Is Expanded Polystyrene EPS STYROFOAM™ Foam the Same?
