The water buoyancy per cubic metre of EPS is determined by subtracting its kg/m3 density from 1000. It is produced from solid beads of polystyrene. The density of EPS is low compared to water, with a normal density range of 11 to 32 kg/m3 compared to water at 100 kg/m3. This means that EPS can be used in a lightweight fill application, where it is used in the place of low bearing capacity foundation soils or heavy fill materials, to prevent the associated issue of unacceptable rates of settlement. The EPD applies to 1 m³ and 1 m² with R-value 1 (in EPD Annex) with average density of 20 kg/m³. EPS Size & Density. Some mattress brands use the terms ‘density… EPS foam density. Its uniform, closed cellular structure limits radiant, convective and conductive heat transfer. Standard-sized EPS foam insulation is available in multiple sizes up to 36-inches thick and 16-feet long or larger. The data on fatigue properties of PU foams are generally lacking. density, STYROBAR® can be produced with a variety of qualities suited to particular applications ranging from insulating boards to lightweight structural units. EPS protective packaging offers a broad range of physical properties to the designer and user. #SurfEPSpecific. If used as a soft bed topper by an average-sized individual every day, a 1.5LB density foam will begin to show a noticeable decline in support and comfort after six months to a year. All substances of unknown composition should be tested for compatibility. The volume resistivity of molded polystyrene within the 1.25-2.5 pcf density range, conditioned at 73° F and 50% r.h. is 4x1013 ohm-cm. At frequencies up to 400 MHz, the permittivity is 1.02-1.04 with a loss factor less than 5x10-4 at 1MHz and less than 3x10-5 at 400 MHz. The result is the weight in kilograms that a cubic metre of EPS can support when fully submerged in water.

By doing this we get a foam sheet that is flat, has a better surface finish, and a more uniform thickness than is typically available from insulation suppliers. EPS is created in a two-stage process:Raw beads are expanded using steam, creating pre puff beads, which are then cured in large bags before being conveyed to the mold. These properties, in combination with satisfactory engineering considerations provide the design flexibility required to create truly cost-effective protective packaging.With the average package handled by up to nine different people and with more than 445,000 packages a day per distribution facility, the risks of the distribution environment can be great. Expanded polystyrene foam (EPS) produced by EUMEPS members. Strongly relied upon in the food distribution industry, EPS is ideal for long distance shipment of perishable foods. Density is a function of the chemistry used to produce the foam and additives included with the foam chemistry. is ideal for many applications requiring high-strength insulation board. However, variables such as the grade of raw material used, geometry of the molded part and processing conditions will affect package properties and performance. Expansion is achieved by virtue of small amounts of gas contained within the polystyrene bead. (5-Panels) (106) Model# AMDKIT001 $ 56 08. 0000011227 00000 n
The table below breaks down PCF ranges for low-, medium-, and high-density polyfoams and memory foams. These values are the common density range for EPS foam for bicycle helmets [12], and they were de fined by the stress-strain curve of EPS with different densities as shown in Figure 3 [13]. Use Benchmark Foam’s High-Density EPS as a thermal barrier be-neath the concrete slab when installing a radiant floor heating sys-tem. Millions of manufacturers over the past 40 years have relied on EPS transport packaging because of its exceptional cushioning properties and high tensile strength. Dry EPS R-value ranges from 3.1 to 4.3 R per inch depending on density. –31-37; Tensile strength, p.s.i. Howzit! These cells occupy approximately 40 times the volume of the original polystyrene bead. Less-expensive EPS—typically sold at home improvement warehouse stores—is 0.4 kg (1 lb) density per 0.02 m 3 (1 cf), appropriately called Type-I density EPS. – 58-61; Thermal resistance, R/in. The higher the density of the product, then the higher the R-value will be. A higher pcf can make a product more expensive, but it can heighten the quality of the product as well. Without the right tools, making those cuts and shapes can be messy, time-consuming, and a real hassle. ICA’s new state-of-the-art Hirsch mold allows us to manufacture block sizes anywhere from 37-1/2″ – 54″ x 49″ x 121-1/2″ – 220″.

EPS (Expanded Polystyrene) or as many know by The Dow Chemical Company's trademarked name, STYROFOAM, is an extremely lightweight product that is made of expanded polystyrene beads.Originally discovered by Eduard Simon in 1839 in Germany by accident, EPS foam is more than 95% air and only about 5% plastic. Many kinds of polyethylene are known, with most having the chemical formula (C₂H₄)nH₂. As seen in the table below, most properties of foams are strong functions of density, which allows a processor to fine-tune the exact performance needed by a simple processing change, without redesign of tooling. Joined: 02/23/2005 . The data are largely dependent on foam producer, as used substrates and production technology decide on intrinsic structure and foam density, and in such a manner - on capacity to carry mechanical loads. Generally, strength characteristics increase with density. 2. EPE is white, light, flexible and able to bend. The density chart below offers great choices for lightness and strength. It is meant to fill empty space or to be used as insulation and strangely, this is the quality of EPS that many surf manufactures use to build surfboards. ). EPS is highly resistant to heat flow. However, one of the most confusing things about foam is the relationship between these characteristics. Newsletter. The actual R-value of EPS depends on its density, with higher-density foams having higher R-values ranging from about 3.6 to 4.2 per 25 mm. Density affects foam durability and support. 0000004153 00000 n
