XPS performs better than EPS. In addition, it’s not necessary to use a highly insulating material as a decorative element; the cheaper option should be more than sufficient. The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. window.mc4wp.listeners.push( Required fields are marked *. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. 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. Remember that expanded polystyrene is simply lighter, thicker, and less insulating than extruded polystyrene. forms : { } Don’t feel alone in this misconception, it is very common. One of the main functions is to provide insulation and protect surrounding structures and is widely used for building insulation. Save my name, email, and website in this browser for the next time I comment. Expanded Polystyrene (EPS) Insulation is a rigid closed cell plastic foam that is comprised of hollow, spherical beads that are fused together using steam. It exists in two types: expanded polystyrene (EPS) and extruded polystyrene (XPS). It is an inexpensive resin per unit weight. Polystyrene panels are primarily used to insulate houses, but they can also be used in the creation of sets for artistic projects, for example. EPS is also used in the construction industr… It’s also less expensive and more manageable for those who don’t have machines adapted to its cutting. Pros & Cons of EPS vs. PUR Insulated Shipping Coolers October 2, 2018 - Chill-Pak - Cold Chain Packaging EPS (aka expanded polystyrene or Styrofoam) insulated shipping coolers are the typical material of choice for human & animal health companies … As it’s quite fragile when it comes into contact with fire, it’s necessary to combine expanded polystyrene with a non-combustible material. What is Expanded Polystyrene? EPS - Expanded Polystyrene Foam Insulation Boards: Rated at R4 per inch; EPS foam insulation boards are more permeable to air and moisture than XPS, but it doesn't retain moisture to the same extent because of it's more closed cell structure and it's breathability which lets it dry out. Polystyrene panels are very useful when it comes to decorating a place. Lightweight, they’re very easy to transport. EPS has been with us for around 50 years. See for yourself the performance advantages of Extruded Polystyrene (XPS) vs. Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer styrene. The main difference between these two materials lies in their density. R- Value EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material. Insulfoam is a division of Carlisle Construction Materials, a wholly owned subsidiary of Carlisle Companies (NYSE: CSL), and is the nation's largest manufacturer of block-molded expanded polystyrene (EPS). Heat or steam is then applied to the mould which expands the polystyrene beads and fuses them together. However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. Your email address will not be published. Polystyrene is produced from the crude oil refinery product styrene. These repeating units are “monomers”. Saint-Jean-Baptiste Montréal (Québec) H1B 5V3. on average for XPS vs. 0.93 lbs. Once it’s cut, the panel will be transformed into a fully fledged decorative element. Although manufacturers of XPS and EPS often tout the fact that their products can be recycled, a complete life cycle analysis shows that EPS has a better overall environmental impact when compared to XPS. Expanded polystyrene or EPS is a thermoplastic foam material that we produce from solid beads of polystyrene whereas the extruded polystyrene or XPS is a foam material that we produce from solid polystyrene crystals. While XPS is "extruded" into a close approximation of its final form, EPS is manufactured in large blocks that are subsequently cut by hot-wire machines into sheets or cut into virtually any special shape or form by computer-driven systems. However, grey polystyrene is slightly more expensive. 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. This is the key difference between expanded and extruded polystyrene. General-purpose polystyrene is clear, hard, and rather brittle. Polystyrene is commonly injection molded, vacuum formed, or extruded, while expanded polystyrene is either extruded or molded in a special process. 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. listeners: [], By: Agence Combustible|Published on: Nov 2, 2017|Categories: News, Uncategorized| 0 comments. for EPS). The Difference between Expanded Polystyrene and Extruded Polystyrene. EPS is one of the most commonly used PS foam in everyday life. 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. The food service industry is a major user of this product, which makes strong, protective, and insulating trays, cups, and containers. Unique Properties of EPP. Polystyrene vs. Polyurethane Garage Door Insulation. 2 lb nominal density EPS (expanded polystyrene) has become a very popular alternative to extruded polystyrene for under slab and perimeter foundation wall insulation. Polystyrene itself is a form of plastic, a polymer that can be extruded (think Styrofoam®) or expanded. Monomers bind with each other via covalent bonds to form a polymer. } These qualities are especially appreciated in Québec. For over 50 years, Insulfoam has been enabling building professionals to construct high-quality building insulation systems at a minimal cost. on average for XPS vs. 0.93 lbs. Polystyrene can be solid or foamed. window.mc4wp) { Expanded polystyrene (EPS) can also be made out of recycled polystyrene. Polyisocyanurate’s typical R-value for the same 1″ of material is approximately 6.0. Polystyrene panels are very useful when it comes to decorating a place. The Advantages of Expanded Polystyrene EPS is a … It’s also highly resistant to different temperatures: heat, cold, and water are usually unsuccessful at overcoming quality extruded polystyrene. Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. Molded Pulp vs. Cost. window.mc4wp = { Because EPS insulation is 98% air, it is chemically inert. Expanded Polystyrene (EPS) is one of the most economic and cost-effective options for insulating your home. Styrofoam™ is a Dow trade name and is actually blue in color. The white stuff most everyone refers to as “Styrofoam” is actually EPS, expanded polystyrene. 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.) (function() { It is usually white in appearance and produced from pre-expanded PS beads. The main difference between these two materials lies in their density. Saint-Jean-Baptiste Montréal (Québec) H1B 5V3. For a Silicone Silicate render system with EPS of 100mm thickness the cost per pack of 6 sheets (Size: 1000mm x 500mm) is £8.33 while for mineral wool of 100mm the cost per pack of 2 sheets (Size: 1200mm x 600mm) is £14.58. On the other hand, if this element needs to have a minimum resistance, then it will be better to opt for extruded polystyrene. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. EPS (Expanded Polystyrene) or as many know by The Dow Chemical Company's trademarked name, STYROFOAM, is an extremely lightweight product that is made of expanded polystyrene beads.Originally discovered by Eduard Simon in 1839 in Germany by accident, EPS foam is more than 95% air and only about 5% plastic. 5025, boul. Polyurethane was produced to replace the shortfalls of expanded polystyrene. ); 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. 5025, boul. } However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. Polystyrene. Polyurethane is a new product with roughly 35 years of testing. The choice of a recycling method is based on technical, environmental and economic considerations. But these two products could not be more different. Those who want to create specific shapes will have more reasons to hesitate between expanded and extruded polystyrene. on: function (event, callback) { The difference between EPP and EPS lies in the manufacturing process where the distinctive resin (polypropylene vs polystyrene) goes through a different process under tightly controlled conditions. The puffing of EPS resin, creating the puffed polystyrene beads is the first step in producing EPS (expanded polystyrene) blocks. The white foam is commonly used for … Since XPS is typically more expensive than EPS, buyers need to closely compare the tables of properties for each product as compared to the needs of the application. The Long Term Thermal Resistance (LTTR) of XPS is therefore less than its "initial" R-factor. EPS is also used in the construction industry for insulation and void fill. Extruded polystyrene (XPS) was shown to have lost R-Value over time. Expanded Polystyrene – EPS. } FMI-EPS | Learn the difference between Expanded Polystyrene (EPS) & Extruded Polystyrene (XPS) See why EPS holds a better R-Value compared to XPS Address EPS can be recycled in many ways once it comes to the end of its life. Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene. EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets. They can be found in different forms, but the polystyrene panel is undoubtedly the most commonly used. Expanded Polystyrene (EPS). These include recycling directly into new building products and incineration to recover its inherent energy content. Expanded polystyrene – Made from expanded foam beads that are molded into shape, expanded polystyrene or EPS is ideal for above-grade applications such as exterior walls and offers an R-value of 3.6 to 4.2 per inch. 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. The 2 lb EPS is available in any thickness, not just 1″ increments and is more economical than extruded polystyrene. Expanded Polystyrene (EPS) EPS or expanded polystyrene packaging has historically been a popular choice for protecting products in distribution. R- Value – P olyurethane is the most efficient manmade insulation in the world. In addition, it’s not necessary to use a highly insulating material as a decorative element; the cheaper option should be more than sufficient. This was clearly shown in an independent, third-party test. It’s primarily used in the form of white or grey panels to insulate floors, walls, roofs, or terraces. Expanded polystyrene foam is made by expanding the polystyrene plastic polymers to form a white, closed-cell foam material. EPS is also easily worked in the field during installation. 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. Prototype Manufacturing: Why Opt for an Incubator? Polystyrene granulate is prefoamed at temperatures above 90°C. What is Expanded Polystyrene or EPS Polystyrene Foam? No, we are not kidding, it is blue in color! Each process is briefly explained below. Extruded polystyrene has other advantages. Finally, XPS is often branded by its manufacturer and frequently comes in a number of different colors which have nothing to do with performance. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. Expanded Polystyrene has been used for approximately 50 years. 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. event : event, Polyurethane Vs. EPS (Expanded Polystyrene) Panels in Comparison. if ( ! Your email address will not be published. Polyurethane is a relatively new product, roughly around 35 years. For example, it’s equipped with a higher mechanical resistance than EPS. Material costs are about &0.31 per square foot for each inch of thickness, plus installation costs. It must also be noted that stated R-values of insulations products vary under different conditions and truly credible comparisons must take into consideration the specific brands of foam and specific test conditions. Polystyrene has a typical R-value of approximately 4.4 per 1″ thickness of material. It is a light-weight and rigid foam, which is produced from solid beads of polystyrene. for EPS). XPS is primarily used in the form of blue panels for insulating floors and roofs (flat). { XPS & EPS Differentiators. Polyurethane has been developed to alleviate the shortfalls of EPS. EPS is a lightweight insulator with a high mechanical resistance. This is a relatively simple project that can reap great benefits, but with the wide variety of approaches you can take to insulate your garage, how do you choose the one that is right for you? Its lightness makes it easy to handle and install. Expanded polystyrene (EPS) is the winner! The battle began, EPS versus XPS, and the test results are in. } XPS has good thermal conductivity (generally higher than EPS). Lightweight, they’re very easy to transport. Expanded polystyrene maintains its R-Value even after long-term exposure in northern climates. callback: callback If it’s only handled a little, expanded polystyrene will largely do the trick. Polystyrene beads are often mistakenly referred to as STYROFOAM™ beads. The R-factor of EPS remains constant over the life of the product because the manufacturing process used in EPS results in normal air, rather than gas, in the voids in the product. It’s therefore preferred in areas with rather extreme weather conditions. Although the same material they manufactured differently; EPS beads are molded or cut into various sizes and shapes while XPS is extruded sheets. 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. The EPP manufacturing process is complex. These plates are mainly appreciated for interior insulation. Expanded polystyrene (EPS), is produced from small beads of polystyrene that are fed into a mold. EPS (expanded polystyrene) and XPS (extruded polystyrene) are both closed-cell rigid insulation made from the same base polystyrene resins. Sitemap Privacy Contact Us © 2019 TrueFoam Limited. You Decide?? })(); Votre adresse courriel: Your email adress: Polystyrene is a material that comes from the family of synthetic insulators. Generally, polystyrene is a synthetic aromatic polymer made from the monomer styrene, which is derived from benzene and ethylene, both petroleum products.Polystyrene can be solid or foamed. EPS (Expanded Polystyrene) Vs Polyurethane. A SCULPTURE ENLARGEMENT FOR THE WINNER OF THE LAST SCVLPTVRE SHOW, 100,000$ INVESTMENT FOR NEW TECHNOLOGY AT USIMM. As you can see, these materials may seem very similar, but they have very different qualities. Expanded Polystyrene (EPS) EPS is a kind of rigid, tough and closed foam. XPS cells contain insulating gases in addition to air that eventually diffuses out of the cells, thus lowering the insulating value. Puffed polystyrene beads are used for several different applications besides the manufacture of EPS … It doesn’t warp much, even over time, and doesn’t lose its thickness. Expanded vs. Extruded Polystyrene. Plaster is often used with expanded polystyrene and combined in the form of a plate. So, you’re thinking about insulating your garage door.
