Once it’s cut, the panel will be transformed into a fully fledged decorative element. The EPP manufacturing process is complex. As it’s quite fragile when it comes into contact with fire, it’s necessary to combine expanded polystyrene with a non-combustible material. They can be found in different forms, but the polystyrene panel is undoubtedly the most commonly used. Don’t feel alone in this misconception, it is very common. Plaster is often used with expanded polystyrene and combined in the form of a plate. 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.) on: function (event, callback) { EPS has been with us for around 50 years. 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. Expanded polystyrene (EPS) can also be made out of recycled polystyrene. Those who want to create specific shapes will have more reasons to hesitate between expanded and extruded polystyrene. XPS has good thermal conductivity (generally higher than EPS). Expanded Polystyrene (EPS) Insulation is a rigid closed cell plastic foam that is comprised of hollow, spherical beads that are fused together using steam. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. Polystyrene granulate is prefoamed at temperatures above 90°C. window.mc4wp.listeners.push( R- Value – P olyurethane is the most efficient manmade insulation in the world. Polystyrene beads are often mistakenly referred to as STYROFOAM™ beads. EPS is one of the most commonly used PS foam in everyday life. The key difference between polystyrene and polypropylene is that the monomer for polystyrene is styrene, while the monomer for polypropylene is propylene.. Polymers are large molecules, which have the same structural unit repeating over and over. The white stuff most everyone refers to as “Styrofoam” is actually EPS, expanded polystyrene. event : event, Below you will see a detailed difference between polyurethane, and expanded polystyrene. The battle began, EPS versus XPS, and the test results are in. It exists in two types: expanded polystyrene (EPS) and extruded polystyrene (XPS).

Most common foam products, like coolers, wine shippers, molded end caps and corners, box packaging and even cups at the office water cooler are actually polystyrene foam. R- Value It is a light-weight and rigid foam, which is produced from solid beads of polystyrene. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material. XPS cells contain insulating gases in addition to air that eventually diffuses out of the cells, thus lowering the insulating value. What is Expanded Polystyrene or EPS Polystyrene Foam? For example, whether it’s a stage play or a shop display case to be decorated, these panels can act as false partitions and create a specific atmosphere if they’re dressed up. for EPS). Extruded polystyrene has other advantages. The Difference between Expanded Polystyrene and Extruded Polystyrene. It’s worth noting that grey EPS shows a better thermal performance (around 10 to 20%), which makes it possible, for example, to reduce the thickness of the polystyrene panel when it’s used as insulation. These repeating units are “monomers”. However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. Puffed polystyrene beads are used for several different applications besides the manufacture of EPS … Polystyrene itself is a form of plastic, a polymer that can be extruded (think Styrofoam®) or expanded. This was clearly shown in an independent, third-party test. It is an inexpensive resin per unit weight. Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. 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.
