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. Introduction . However, EPS is also used in the construction industry as an insulating material and can be made in different densities and even with thermal enhancing graphite to provide a cost effective insulation material. The two main types of polystyrene are expanded polystyrene (EPS) and extruded polystyrene (XPS). Expanded PolyStyrene (EPS) does not degrade. Expanded polystyrene is a type of cladding that is combustible and increases the likelihood of fire spreading more quickly. Expanded vs. Extruded Polystyrene. Introduction Expanded Polystyrene, or EPS, […] EPS has a compressive strength between 10-60 psi for most construction applications. It is used for fish boxes, packaging for electrical consumer goods and for insulation panels for building. The distinctive white pre-expanded beads are very recognizable, and display the resin identification code number. Expanded Polystyrene is an effective insulator because it's packed full of tiny air pockets. Insulation Technology, Inc. manufactures EPS (Expanded Polystyrene) Insulation in many shapes and sizes for a broad range of insulating applications. Expanded polystyrene (EPS) is a rigid cellular plastic, commonly used for fish boxes, packaging for electrical consumer goods and for building insulation. Expanded polystyrene, or EPS geofoam, is a cost-efficient insulation material used in the construction industry. It is usually white and made of pre-expanded polystyrene beads. Polystyrene boards are also called foam boards or bead boards. Expandable polystyrene (EPS) is produced in a suspension process by adding a blowing agent, usually pentane, which causes resin to foam during moulding. Both begin with the same basic raw material. It is unique in that it is a closed cell, rigid, polymeric material that is about 95% air. Expanded polystyrene (EPS) has been extensively tested in terms of fire hazard assessments. Expanded polystyrene (EPS) is a crushable foam, widely used in helmet liners (and other energy management applications like automobile bumpers). EPS is ideal for the packaging and construction industries due to its light weight, strong and excellent thermal insulation properties. EPS is also used in the construction industry for insulation and void fill. 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. EPS is a closed cell, light-weight, resilient, foamed plastic composed of hydrogen and carbon atoms. expanded polystyrene. STYRO Expanded polystyrene “EPS” is a rigid cellular plastic foam comes from petroleum. 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. Like ACP, this material is a very dangerous, flammable material that has many advantages as a building material despite this issue. It is a lightweight, rigid, plastic foam insulating material produced from solid beads of polystyrene. Define expanded polystyrene. These are the most commonly German / Deutsch: Styropor®. The process may be performed as a single step or a two step process. Translations. Expanded Polystyrene (EPS) is a rigid cellular plastic, which is found in a multitude of shapes and applications. The design of the form dictates the finished size and shape of the polystyrene block. The EPS process involves mixing unexpanded polystyrene beads with a liquid bonding agent. Expanded Polystyrene has been the proven answer to common packaging, insulative, and construction material solution for decades. Its strength, durability and lightweight nature makes it a versatile and popular building product. This makes it a bit of a nuisance from a landfill perspective (although at least it doesn’t seep into our water table). 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. 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).
