However, low-density EPS not subjected to load will show no noticeable loss of dimensional stability at temperatures up to 184°F. A low-density foam can still be firm or hard. EPS. 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. When choosing EPS, original equipment manufacturers realize cost savings across the board. The dielectric strength of EPS material is approximately 2KV/mm. x 48 in.

Standard-sized EPS foam insulation is available in multiple sizes up to 36-inches thick and 16-feet long or larger. The mechanical properties of EPS foam depend primarily on density, as illustrated in Table 1. Use Benchmark Foam’s High-Density EPS as a thermal barrier be-neath the concrete slab when installing a radiant floor heating sys-tem. Amvic Multipurpose High Density Insulation Kit R10 2-3/8 in. Density is a function of the chemistry used to produce the foam and additives included with the foam chemistry. Insulfoam EPS Rigid Foam Insulation. 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]. 7 posts / 0 new .

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″. Home  |  News & Announcements  |  Contact Us  |  Related Links  |  Privacy Policy. For specification purposes, it is advisable to use the polymer density of the foam, or the density of the material made up strictly by the foam chemistry without fillers or reinforcements included. 0000019307 00000 n Atlas Molded Products specializes in the development and manufacture of innovative, high-quality, HFC- and HCFC-free Expanded Polystyrene (EPS) insulation for construction, packaging and OEM products.

Because a molding process is used to produce EPS foam, there are more sizes available to select from, compared to XPS foam board which comes in limited sheet sizes. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. Generally, strength characteristics increase with density, however the cushioning characteristics of EPS foam packaging are affected by the geometry of the molded part and, to a lesser extent, by bead size and processing conditions, as well as density. ). 0000001332 00000 n It has almost same kind of chemical composition as of the EPS but produced with a different kind of technology. The water buoyancy per cubic metre of EPS is determined by subtracting its kg/m3 density from 1000. 0000000987 00000 n Picture a styrofoam cup for example. Benchmark Foam’s closed-cell High-Density EPS expanded polystyrene . The performance of these foams has to be studied as a function of several parameters such as density, microstructure and also the strain rate imposed during dynamic loading. 0000012027 00000 n Many temperature sensitive pharmaceutical and medical products use EPS because comparable packaging materials can rarely offer the same level of thermal insulation. ft. for a single, 1-inch 4×8 sheet. EPS protective packaging offers a broad range of physical properties to the designer and user. EPS foams can be used to absorb energy. 0000010885 00000 n How density is measured varies across materials though, and in the case of foam, density is found by weighing a 12″ x 12″ x 12″ block of the material. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3.

The thermal conductivity (k factor) of molded polystyrene varies with density and exposure to temperature, as shown in the table below. please contact us! Density tells you the weight of the foam more accurately than the firmness. A mattress with a 5.0 foam density doesn’t say much about the love seat you’re considering, for instance. However, one of the most confusing things about foam is the relationship between these characteristics. Size and density. 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. In addition, it is resistant to many solvents including styrene and most fuels, yet is compatible with most adhesives and laminating resins. Beyond its competitive material pricing, EPS – because of its versatility and lightweight characteristics – can offer savings in design and development, product assembly and distribution costs. What is Superwhite Foam? Surf specific EPS. Firstly, EPS is an ultra lightweight material that has a density of approximately 1/100th of other conventional fill materials (see Table 1). Expanded polystyrene foam (EPS) produced by EUMEPS members. I'd need to know which foam density is to prefer for building an eps surfboard. 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. EPS protective packaging offers a broad range of physical properties to the designer and user. x 24 in. 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. 0000009281 00000 n The blocks are then placed on the storage floor to age for the appropriate length of time before being cut into various shapes and sizes. 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. Its uniform, closed cellular structure limits radiant, convective and conductive heat transfer. However, EPS may absorb moisture when it is completely immersed due to its fine interstitial channels within the bead-like structure. (5-Panels) (106) Model# AMDKIT001 $ 56 08. If a product has a 3LB density, that means its 12″ x 12″ x 12″ block weighed 3LB. XPS is another form of a foam which offers improved surface roughness and higher stiffness with reduced thermal conductivity. PE foam (Polyethylene foam) is the most common and largest production plastic, a kind of thermoplastic resin. Densities can range from 10 grams per litre (0.6 pounds per cubic foot) to 48 grams per litre (3.0 pounds per cubic foot). ASTM C578 Standard Specification for Rigid Cellular Polystyrene Thermal Insulation addresses the physical properties and performance characteristics of EPS foam as it relates to thermal insulation in construction applications. 6'4" LITE EPS Blank; 7'0" LITE EPS Blank; 6'8" Lite EPS Blank; About Why We Do It. 3/4 in. 0000019244 00000 n Density, lb./cu.ft. Expanded Polystyrene (EPS) is the generic industry name used for white rigid material made from the expanded polystyrene beads. A common misunderstanding is that the density of foam – in a mattress or pillow for example – determines its firmness. Here at ICA we manufacture Low Density EPS foam blocks all the way up to 2.85 lb density. 72 sq. x 1.25 ft. x 4 ft.
