The word Styrofoam™ is often used to describe expanded polystyrene (EPS) foam; however, ‘Styrofoam’ is actually a trademarked term for closed-cell extruded polystyrene foam made for thermal insulation and craft applications. Polystyrene foams are used for a variety of applications because of its excellent set of properties including good thermal insulation, good damping properties and being extremely light weight. The foam plastic consists of 96 – 98% air and 2-4% polystyrene. Seed Trays 72. Polystyrene is a synthetic, hydrocarbon polymer derived from benzene and ethylene, two petroleum products. The strength of EPS foam along with its shock absorbing properties makes it effective for use in childrens seats and cycling helmets. Polystyrene is also a very good insulator, meaning that it quickly accrues electrical charge. EPS foam is perhaps the most common in everyday life: this white foam can be seen in cups for hot beverages, refrigerators, insulation, packaging, etc. More than half of the styrene produced is made into polystyrene, a light, stiff plastic widely used in injection-molded or foamed articles. XPS is manufactured in a continuous extrusion process that produces a homogeneous closed cell crossed section, whereas EPS is manufactured by expanding spherical beads in a mold, using heat and pressure to fuse the beads together. Polystyrene sulfonates are a group of medications used to treat high blood potassium. At EWI Store, we stock two types of polystyrene insulation, EPS and XPS. The uses for these pellets is ever expanding, so they may be used even more widely in the future. It is produced by the polymerization of styrene and is the most widely used plastic. Although the Styrofoam brand has become the common term for polystyrene, Styrofoam is mostly used as insulation rather than as craft material because it is a harder foam. You can unsubscribe at any time. Extensively used for seating applications and integrated with other components and materials. In solid form, it is a colorless and rigid plastic, but it may also be returned to a liquid state by heating, and used again for molding or extrusion. It is used to build up bridge embankments, … Polystyrene film is made by the polymer of styrene. These are both ideal for use with external wall insulation systems, offering an effective method of lowering energy bills by improving the thermal performance of properties. EPS insulation material also has applications in horticulture in seedling trays to promote aeration of soil. Effects generally take hours to days. Plant Pots 73. It is typically used for POP Display, Indoor Signage, and other common displays. Composite products, also known as fiber-reinforced polymer composites (FRP): used in automobile components, military and commercial aircraft, boats, wind turbine parts, corrosion-resistant pipes and tanks, bathroom fixtures, sporting goods, and many other applications. Expanded polystyrene, or EPS geofoam, is a cost-efficient insulation material used in the construction industry. Polystyrene is also a very good insulator, meaning that it quickly accrues electrical charge. Polystyrene can be naturally transparent, but can be coloured with colourants. It’s easy to snap in half or crumble but, crucially, it’s strong in compression and therefore protects delicate objects if dropped or crushed. It becomes rigid again when it cools down. What is Polystyrene (PS)? Insulation foam – EPS, XPS are used for a variety of applications because of its excellent set of properties including good thermal insulation, good damping properties and being extremely light weight. Sign in to manage your newsletter preferences. Polystyrene is the material of choice for packaging because it’s nice and light. Most of the foam boards used with stucco in the one coat system are made out of polystyrene, which is moisture repellent and relatively rigid in terms of its structure. Expanded polystyrene does not lose its fundamental properties with time and can be completely recycled and reused. Polystyrene, which is number 6, presents more problems. Thanks! Granules are heated with steam in such a way that they are rapidly expanding (foaming) and forming a low-density block (in a special form). Manufactured into different shapes, sizes and compression materials. Polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. 7.26. 4) Polystyrene use for making crafts. 2) Polystyrene beads to fill and refill bean bag, cushions, pillow, etc. The material is used today for CD and DVD jewel cases and plastic forks. Polystrene is similar to polystyrene foam, but is harder and more durable. Kayexalate works differently from other medicines because it passes into your intestines without being absorbed into your blood stream. The extruded polystyrene foam is a fine laminate that is only 2-3 mm thick. From being used as building materials to white foam packaging, expanded polystyrene has a wide range of end-use applications. XPS foam board is often used for above-grade insulation applications such as walls, ceilings, attics and roofs as well as for below-grade applications such as foundations and basements. They are also used to remove potassium, calcium, and sodium from solutions in technical applications..
