For over 50 years, Insulfoam has been enabling building professionals to construct high-quality building insulation systems at a minimal cost. Expanded PolyStyrene (EPS) does not degrade. This makes it a bit of a nuisance from a landfill perspective (although at least it doesn’t seep into our water table). "Polystyrene (PS) is used in things like yogurt pots and coffee lids (amongst various others). Polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. It is a lightweight, rigid, plastic foam insulating material produced from solid beads of polystyrene. EPS is generally white and made of pre-expanded polystyrene beads. expanded polystyrene synonyms, expanded polystyrene pronunciation, expanded polystyrene translation, English dictionary definition of expanded polystyrene. EPS is sometimes called “Styrofoam”, though that particular name actually refers to a single trademarked brand of EPS owned by Dow Chemical. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. 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. Insulation Technology, Inc. manufactures EPS (Expanded Polystyrene) Insulation in many shapes and sizes for a broad range of insulating applications. These are the most commonly Expanded polystyrene is a type of cladding that is combustible and increases the likelihood of fire spreading more quickly. Air is a very poor conductor of heat so heat transfer is minimised. It is unique in that it is a closed cell, rigid, polymeric material that is about 95% air. Composed of individual cells of low density polystyrene, EPF is extraordinarily light and can support many times its own weight in water. The EPS beads are expanded and finally molded into larger EPS blocks which are further used for walls, roofs, floors, crawl spaces.. This is more expensive and more effective than expanded polystyrene insulation. 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. Expansion is achieved by virtue of small amounts of gas contained within the polystyrene bead. It is commonly used as insulation. Because its cells are not interconnected, heat cannot travel through EPF easily, so it is a great insulator. 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. English: expanded polystyrene n Styropor® nt. Polystyrene boards are also called foam boards or bead boards. See more ideas about Polystyrene, Expand, Construction applications.
