Expanded polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls that are expanded through a molding process in our factories to create a cost effective, highly efficient material used in hundreds of different applications. Learn more. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. The manufacturing process for extruded polystyrene (XPS) foam products is similar to the manufacturing process of expanded polystyrene (EPS) foam products. Polystyrene boards are also called foam boards or bead boards. expanded polystyrene synonyms, expanded polystyrene pronunciation, expanded polystyrene translation, English dictionary definition of expanded polystyrene. The EPS beads are expanded and finally molded into larger EPS blocks which are further used for walls, roofs, floors, crawl spaces.. Expanded polystyrene is a type of foam made from polystyrene. It is widely employed in the food-service industry as rigid trays and containers, disposable eating utensils, and foamed cups, plates, and bowls. 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. Its strength, durability and lightweight nature makes it a versatile and popular building product. Expanded Polystyrene Casting In the expanded polystyrene casting process, a sand mold is packed around a polystyrene pattern representing the metal casting to be manufactured. Expanded polystyrene is a type of cladding that is combustible and increases the likelihood of fire spreading more quickly. Translations. The key difference between expanded and extruded polystyrene is that we produce expanded polystyrene (or EPS) from solid beads of polystyrene while we produce extruded polystyrene (or XPS) from solid polystyrene crystals.. Expanded polystyrene (EPS) is a crushable foam, widely used in helmet liners (and other energy management applications like automobile bumpers). However, it does make them useful in plant pots. Expanded Polystyrene (EPS) < back. The distinctive white pre-expanded beads are very recognizable, and display the resin identification code number. It is a lightweight, rigid and closed cell insulation. Polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. Expanded polystyrene, or EPS geofoam, is a cost-efficient insulation material used in the construction industry. It may shrink, melt or ignite when exposed to elevated temperatures. 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. German / Deutsch: Styropor®. It is this design that makes expanded polystyrene insulation less effective. Because its cells are not interconnected, heat cannot travel through EPF easily, so it is a great insulator. Expanded polystyrene, or EPS, is a plastic material derived from crude oil used in a variety of applications, including thermal insulation in buildings, civil engineering applications and decorative mouldings and panels. Introduction . The EPS process involves mixing unexpanded polystyrene beads with a liquid bonding agent. It is unique in that it is a closed cell, rigid, polymeric material that is about 95% air. See more ideas about Polystyrene, Expand, Construction applications. EPS is a closed cell, light-weight, resilient, foamed plastic composed of hydrogen and carbon atoms. Extruded Polystyrene Insulation. It is used for fish boxes, packaging for electrical consumer goods and for insulation panels for building. During the forming process, the foam beads are expanded to fill a form. EPS has a compressive strength between 10-60 psi for most construction applications. For over 50 years, Insulfoam has been enabling building professionals to construct high-quality building insulation systems at a minimal cost. Polystyrene blocks use expanded foam beads to form a solid material that is lightweight, easily cut and has enough strength to be used as concrete forms. EPS is generally white and made of pre-expanded polystyrene beads. Expanded Polystyrene (EPS) is a rigid cellular plastic, which is found in a multitude of shapes and applications. This is more expensive and more effective than expanded polystyrene insulation. Introduction Expanded Polystyrene, or EPS, […] The process may be performed as a single step or a two step process. Expanded polystyrene has been used widely in the building industry in … It is extremely lightweight, but strong and durable. 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). Expanded polystyrene (EPS) refers to a rigid, tough and lightweight thermoplastic product. Expanded Polystyrene (EPS) has become known for its role in smaller combustible cladding fires over the last 20 years due to its very flammable composition. EPS is ideal for the packaging and construction industries due to its light weight, strong and excellent thermal insulation properties. Insulation Technology, Inc. manufactures EPS (Expanded Polystyrene) Insulation in many shapes and sizes for a broad range of insulating applications. XPS & EPS Differentiators. Expanded Polystyrene (EPS): Production, Price, Market and its Properties. EPS is also used in the construction industry for insulation and void fill. It is commonly used as insulation. These are the most commonly Expanded Polystyrene is an effective insulator because it's packed full of tiny air pockets. The two main types of polystyrene are expanded polystyrene (EPS) and extruded polystyrene (XPS). Expanded vs. Extruded Polystyrene. Building and Construction EPS is used widely in the building and construction industry. The gas expands when heat in the form of steam is applied, thus forming closed cells of EPS. Artists use rigid, but versatile polystyrene board. The foam plastic consists of 96 – 98% air and 2-4% polystyrene. The pattern is not removed, and the molten metal is poured into the pattern which is vaporized from the heat of the metal. It is a lightweight, rigid, plastic foam insulating material produced from solid beads of polystyrene. Polystyrene is also copolymerized, or It is produced from solid beads of polystyrene. Expanded polystyrene (EPS) is a rigid cellular plastic, commonly used for fish boxes, packaging for electrical consumer goods and for building insulation. "Polystyrene (PS) is used in things like yogurt pots and coffee lids (amongst various others). Expanded polystyrene foam (EPF) is a plastic material that has special properties due to its structure. The cell walls help … Both begin with the same basic raw material. Expanded PolyStyrene (EPS) does not degrade. Air is a very poor conductor of heat so heat transfer is minimised. This makes it a bit of a nuisance from a landfill perspective (although at least it doesn’t seep into our water table). EPS is an inert material that does not rot and provides no nutritional benefits to vermin therefore does not attract pests such as rats or termites. English: expanded polystyrene n Styropor® nt. The design of the form dictates the finished size and shape of the polystyrene block. EPS is a closed cell foam, meaning every cell is closed off to the other cells that surround it. expanded polystyrene definition: 1. a light plastic that contains gas and is used for wrapping things in before putting them in…. Expanded polystyrene (EPS) has been extensively tested in terms of fire hazard assessments. Like ACP, this material is a very dangerous, flammable material that has many advantages as a building material despite this issue. Expanded polystyrene (EPS) is often associated with poor quality packaging that comes wrapped around new consumer goods such as TVs or washing machines. 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. Expandable polystyrene (EPS) is produced in a suspension process by adding a blowing agent, usually pentane, which causes resin to foam during moulding.
