These It becomes rigid again when cooled. STYROFOAM™ vs Polystyrene - What's the Difference? OVERVIEW. The key difference between polystyrene and Styrofoam is that the polystyrene is a form of synthetic aromatic hydrocarbon polymer whereas the styrofoam is a commercial brand of polystyrene. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. These insulation panels are commonly referred to as "blue board" in the construction industry. or to shape molds. This particular article focuses on two insulation types that are popular in a variety of installations for the entire building envelope: EPS and XPS. Polystyrene (left) is a synthetic aromatic polymer made from the monomer styrene which is also known as Styrofoam. construction industry. Whether selecting EPS or XPS insulation, to ensure performance, confirm that the product was manufactured to meet the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. Expanded Polystyrene (EPS) Insulation is a rigid closed cell plastic foam that is comprised of hollow, spherical beads that are fused together using steam. Expanded polystyrene foam, such as is used in cups and packaging. This standard provides a key quality check on rigid insulation. Compatibility – XPS vs EPS Insulation. 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. used to describe expanded polystyrene foam products like disposable As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. Some Rigid foam: These are panels of rigid foam, sold in 4-by-8-foot sheets in a variety of thicknesses from 1/4 to 2 inches.It is also sold in large bundled panels, joined at the ends accordion-style for use as an exterior sheathing material. All rights reserved. are actually STYROFOAM. EPS performs better at mid to upper sound frequency attenuation, and significantly better when used with other materials. STYROFOAM™ has never been used to hold food and for making beverage containers or coolers for the beach - STYROFOAM™ is actually a registered brand of the Dow Chemical company – with very few exceptions they color it light blue to differentiate it from EPS or expanded polystyrene foam, and it is a version of closed-cell extruded polystyrene foam currently made for thermal insulation and craft … Use either extruded polystyrene (XPS) such as Styrofoam or Foamular or expanded polystyrene/EPS, sometimes called “beadboard.” EPS is less expensive and rates about R-4 per inch vs. R-5 for EPS . So, you’re thinking about insulating your garage door. Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.

This temperature behaviour is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail. between Expanded Polystyrene Foam and STYROFOAM Brand Foam?" The higher the R-Value, the greater the insulating power. For contractors working with a building made of concrete, XPS tends to be the preferred form of rigid-foam insulation. Additionally, it is moderately soluble in many organic solvents, cyanoacrylate, and the propellants and solvents of spray paint. However, EPS insulation has proven to perform just as well in such situations. Owens Corning® FOAMULAR® XPS insulation is proven to hold its R-Value better than EPS – and even more so when water is present*, such as in below-grade applications. Expanded vs. Extruded Polystyrene XPS & EPS Differentiators It is commonly understood that XPS offers more initial R-value per inch than EPS but because of its lower cost, EPS offers more R-value per dollar. Definitions . An alkane chain of benzene molecules, RCH2CHphenylR.
