Available here If you're cutting the rigid foam for a specific project, measure the length and width you will need it to be. Measure and mark the dimensions for your cut using the measuring tape and marker. Combining low thermal conductivity and low water absorption, extruded polystyrene has become the first choice for specifiers in a wide range of insulation applications. Extruded polystyrene (XPS) Extruded polystyrene foam (XPS) consists of closed cells. For example, it is not resistant to organic solvents, it is flammable if oil painted, health concerns when using as a packaging material for food items, etc. Then we can shape, cool and trim this material into the desired shape. In the production of this foam material, we can achieve the expansion due to the trapped small amounts of gas inside the polystyrene beads. Compare these dimensions to the length and width that your rigid foam insulation currently has to make sure it's long and wide enough. • Easy to saw, cut or score Product Installation 1. Remove Strawberry Stains From a Cutting Board, Owens-Corning: Owens-Corning Pink Extruded Polystyrene Foam Insulation, Dow Industries: Renovate with styrofoam Brand Extruded Polystyrene Foam Insulation. There are two types of polystyrene foam best suited for processing with the Hot wire foam cutters and Hot knife cutters: extruded polystyrene (XPS foam), and expanded polystyrene (EPS foam). Alt… This material has a superior moisture resistance. One more alternative is to use 2lb./cubic foot (25psi - pounds per square inch) extruded polystyrene foam (XPS) - Dow Square Edge, or "blue board". Laser cutting of polystyrene can be performed with a 9.3 or 10.6 micron CO 2 laser, resulting a clean, smooth, slightly melted cut edge, free of discoloration. Use a cutter to cut the foam and make the surface even. The carbon footprint of EPS is lower than many other packaging materials in use today. Only 0.1% of total oil consumption is used to manufacture EPS. Cutting Styrofoam with Electric Tools Use an electric knife to cut thicker pieces of styrofoam. Polystyrene foam insulation, commonly used for exterior house insulation, is manufactured in a wide variety of thicknesses and strengths. It is a lightweight, rigid and closed cell insulation. Place the caulk in the caulking gun. When it emerges through the die, it expands forming a foam. EPS is also easily worked in the field during installation. Although both types of insulation are comprised of polystyrene, the two types of manufacturing processes produce finished products with very different performance properties. Technical Resources for EPS Geofoam from Universal Foam Products. Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. TECHNONICOL extruded polystyrene has an excellent energy-saving performance due to improved physical and mechanical properties. Hardscape Applications for Expanded Polystyrene. Ideal for low installation heights and has excellent soundproofing qualities. Work the blade through the cut until the blade goes through the board fully. Mainly, it is used as insulation in floors, facades and cold rooms. 2. 2. This results in a viscous plastic fluid, which is hot and thick.

Shipped in poly-wrapped units with individually wrapped or banded 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. A lot less mess than a regular saw blade and the edges are nice and sharp. Polystyrene & Styrofoam technical specifications 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. In addition to extruded polystyrenes other uses is lightweight fill for embankments in the civil engineering industry. Although both types of insulation are comprised of polystyrene, the two types of manufacturing processes produce finished products with very different performance properties. Looking For Polystyrene Prices Or Styrofoam Prices Nationally in South Africa? Grade Beam Forms. It offers a number of valuable advantages: low thermal conductivity, high strength, biological resistance, ecological compatibility and durability of use for more than 40 years. To cut polystyrene foam insulation, all you need are a few household tools and a supply of very sharp utility knife blades. Blend for about a minute. EPS blocks or boards used in building construction are commonly cut using hot wires.

Production [ edit ] Polystyrene is an addition polymer that results when styrene monomers interconnect ( polymerization ). Owens Corning® FOAMULAR® 250 Extruded Polystyrene (XPS) Rigid Foam Insulation is a closed cell, highly moisture-resistant rigid foam board well suited to meet the needs for a wide variety of residential and commercial construction applications. Extruded Polystyrene has been used extensively for model making, including model railways, model boats, surf boards, architectural modelling, sculptures and table top games like Warhammer. Those who want to create specific shapes will have more reasons to hesitate between expanded and extruded polystyrene. For specific applications, extruded polystyrene panels are available scored so they can be snapped at 16” intervals instead of cut. Remember! Often it isn’t even necessary to cut all the way through, you can simply score it and then snap along the scored line.If you’re going to cut a lot of foam, or desire to work with expanded polystyrene, you’ll want to get a hot wire cutter.
