Heat or steam is then applied to the mould which expands the polystyrene beads and fuses them together. The puffing of EPS resin, creating the puffed polystyrene beads is the first step in producing EPS (expanded polystyrene) blocks. No, we are not kidding, it is blue in color! Polystyrene panels are primarily used to insulate houses, but they can also be used in the creation of sets for artistic projects, for example. } Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point. Each process is briefly explained below. Expanded Polystyrene has been used for approximately 50 years. The Advantages of Expanded Polystyrene EPS is a … 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. As you can see, these materials may seem very similar, but they have very different qualities. Expanded Polystyrene – 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. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material. 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. Polystyrene itself is a form of plastic, a polymer that can be extruded (think Styrofoam®) or expanded. 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.) Lightweight, they’re very easy to transport. You Decide?? Expanded Polystyrene (EPS) is one of the most economic and cost-effective options for insulating your home. for EPS). They can be found in different forms, but the polystyrene panel is undoubtedly the most commonly used. Polyurethane Vs. EPS (Expanded Polystyrene) Panels in Comparison. Don’t feel alone in this misconception, it is very common. It’s also highly resistant to different temperatures: heat, cold, and water are usually unsuccessful at overcoming quality extruded polystyrene. Although the same material they manufactured differently; EPS beads are molded or cut into various sizes and shapes while XPS is extruded sheets. on: function (event, callback) { However, grey polystyrene is slightly more expensive. The 2 lb EPS is available in any thickness, not just 1″ increments and is more economical than extruded polystyrene. if ( ! So, you’re thinking about insulating your garage door. As it’s quite fragile when it comes into contact with fire, it’s necessary to combine expanded polystyrene with a non-combustible material. 2 lb nominal density EPS (expanded polystyrene) has become a very popular alternative to extruded polystyrene for under slab and perimeter foundation wall insulation. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. Expanded polystyrene foam is made by expanding the polystyrene plastic polymers to form a white, closed-cell foam material. } However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. It’s therefore preferred in areas with rather extreme weather conditions. 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. R- Value – P olyurethane is the most efficient manmade insulation in the world. One of the main functions is to provide insulation and protect surrounding structures and is widely used for building insulation. })(); Votre adresse courriel: Your email adress: Polystyrene is a material that comes from the family of synthetic insulators. listeners: [], The choice of a recycling method is based on technical, environmental and economic considerations. 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. for EPS). Polystyrene is produced from the crude oil refinery product styrene. 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. By: Agence Combustible|Published on: Nov 2, 2017|Categories: News, Uncategorized| 0 comments. 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. Its lightness makes it easy to handle and install. EPS is also easily worked in the field during installation. ); It’s primarily used in the form of white or grey panels to insulate floors, walls, roofs, or terraces. On the other hand, if this element needs to have a minimum resistance, then it will be better to opt for extruded polystyrene. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. The main difference between these two materials lies in their density. 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. Polyurethane is a relatively new product, roughly around 35 years. This is the key difference between expanded and extruded polystyrene. EPS (expanded polystyrene) and XPS (extruded polystyrene) are both closed-cell rigid insulation made from the same base polystyrene resins. EPS is also used in the construction industry for insulation and void fill. 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. window.mc4wp) { } These plates are mainly appreciated for interior insulation. XPS & EPS Differentiators. A SCULPTURE ENLARGEMENT FOR THE WINNER OF THE LAST SCVLPTVRE SHOW, 100,000$ INVESTMENT FOR NEW TECHNOLOGY AT USIMM.

Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. If it’s only handled a little, expanded polystyrene will largely do the trick. Below you will see a detailed difference between polyurethane, and expanded polystyrene. Expanded polystyrene (EPS), is produced from small beads of polystyrene that are fed into a mold. 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. Polystyrene panels are very useful when it comes to decorating a place. The EPP manufacturing process is complex. FMI-EPS | Learn the difference between Expanded Polystyrene (EPS) & Extruded Polystyrene (XPS) See why EPS holds a better R-Value compared to XPS However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. EPS can be recycled in many ways once it comes to the end of its life. 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. XPS performs better than EPS. This was clearly shown in an independent, third-party test. What is Expanded Polystyrene? For example, it’s equipped with a higher mechanical resistance than EPS. Polyurethane has been developed to alleviate the shortfalls of EPS. Save my name, email, and website in this browser for the next time I comment.

It doesn’t warp much, even over time, and doesn’t lose its thickness. callback: callback } The white foam is commonly used for … Polystyrene panels are very useful when it comes to decorating a place. These repeating units are “monomers”. It exists in two types: expanded polystyrene (EPS) and extruded polystyrene (XPS). Material costs are about &0.31 per square foot for each inch of thickness, plus installation costs. Expanded polystyrene (EPS) can also be made out of recycled polystyrene. 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. Remember that expanded polystyrene is simply lighter, thicker, and less insulating than extruded polystyrene. Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. 5025, boul. XPS has good thermal conductivity (generally higher than EPS). Finally, XPS is often branded by its manufacturer and frequently comes in a number of different colors which have nothing to do with performance. The food service industry is a major user of this product, which makes strong, protective, and insulating trays, cups, and containers. Monomers bind with each other via covalent bonds to form a polymer. R- Value EPS (Expanded Polystyrene) Vs Polyurethane. Extruded polystyrene (XPS) was shown to have lost R-Value over time. forms : { 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. Extruded polystyrene has other advantages. Required fields are marked *. 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) EPS or expanded polystyrene packaging has historically been a popular choice for protecting products in distribution. Expanded vs. Extruded Polystyrene. Polystyrene can be solid or foamed. EPS has been with us for around 50 years. These qualities are especially appreciated in Québec. It is a light-weight and rigid foam, which is produced from solid beads of polystyrene. The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. Polystyrene beads are often mistakenly referred to as STYROFOAM™ beads. Saint-Jean-Baptiste Montréal (Québec) H1B 5V3. Cost. Polystyrene. The main difference between these two materials lies in their density. Once it’s cut, the panel will be transformed into a fully fledged decorative element. Those who want to create specific shapes will have more reasons to hesitate between expanded and extruded polystyrene. 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. Prototype Manufacturing: Why Opt for an Incubator? 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. Puffed polystyrene beads are used for several different applications besides the manufacture of EPS … Because EPS insulation is 98% air, it is chemically inert. The white stuff most everyone refers to as “Styrofoam” is actually EPS, expanded polystyrene.
