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. 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. 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. 72 sq. density, STYROBAR® can be produced with a variety of qualities suited to particular applications ranging from insulating boards to lightweight structural units. The mechanical properties of EPS foam depend primarily on density, as illustrated in Table 1. When choosing EPS, original equipment manufacturers realize cost savings across the board. The thermal conductivity (k factor) of molded polystyrene varies with density and exposure to temperature, as shown in the table below. In addition our EPS blanks are manufactured with up to 10% recycled content and stronger boards stay out of landfills making EPS/epoxy construction the most environmentally sound choice for surfboards. 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. 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″. In general, this is often true, but when appl… Dynamic compression tests were conducted on cubic specimens of EPS foam with side length of 25mm (Figure 1). 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. 0000034867 00000 n Virgin EPS; I-Foam; Stringers +-Poplar Ply; Appelcore; Bamboo; Bass; High Density; Services +-CNC Cutting; 3D Scanning ; Recycling; Deliveries; Where To Buy +-Shapers Who Use Marko; Distributors ; About Us +-Why Marko? 0000005696 00000 n EPS R-value per inch varies with density because the higher the density, the smaller the open void air spaces between beads, which results in a slightly higher R-value. A mattress with a 5.0 foam density doesn’t say much about the love seat you’re considering, for instance. A mattress with a 5.0 foam density doesn’t say much about the love seat you’re considering, for instance. Newsletter. Foam density is also relative and shouldn’t be used to compare different product types. 4 Environmental Product Declaration EUMEPS – Expanded Polystyrene (EPS) Foam Insulation (density 30 kg/m³) show that “no deficiencies are to be expected from EPS fills placed in the ground over a normal life cycle of 100 years.”/Langzeitverhalten 2004/, /Long-term … NEW- Surfblanks Lite EPS; Custom Rockers; Rocker Charts Download – 2; Electrical Properties. However, low-density EPS not subjected to load will show no noticeable loss of dimensional stability at temperatures up to 184°F. What is Superwhite Foam? Once in the mold, the pre puff beads are again steamed to form a block that is anywhere from 37-1/2″ – 54″ x 49″ x 121-1/2″ – 220″. 0000012027 00000 n These cells occupy approximately 40 times the volume of the original polystyrene bead. Lower density foam is also great for occasional-use comfort products. SilveRboard 0.625 in. density of polystyrene foam is equal to 50 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 3.1 pound per cubic foot [lb/ft³], or 0.029 ounce per cubic inch [oz/inch³] . The dielectric strength is approximately 2KV/mm. %PDF-1.2 %���� However, variables such as the grade of raw material used, geometry of the molded part and processing conditions will affect package properties and performance. If you were to tell a stranger that foam has density, weight, and firmness characteristics, he or she would likely understand, given how common the terms are. Styrene Products, Inc. expanded polystyrene (EPS) rigid board foam plastic is for all types of industrial, packaging, and con-struction uses. EPS is hand- and machine-shapeable, although because of the larger cell size, it’s not quite as easy to shape as polyurethane foam. 0000031203 00000 n is ideal for many applications requiring high-strength insulation board. EPS protective packaging offers a broad range of physical properties to the designer and user. Expanded Polystyrene is manufactured in conformance with numerous standards. These properties, in combination with satisfactory engineering considerations provide the design flexibility required to create truly cost-effective protective packaging. Recycled Content – EPS foam may be molded from virgin beads, or a combination of virgin bead and recycled material content. Millions of manufacturers over the past 40 years have relied on EPS transport packaging because of its exceptional cushioning properties and high tensile strength. Table 1 presents the stress and strain values of EPS foam. (5-Panels) (106) Model# AMDKIT001 $ 56 08. PE foam (Polyethylene foam) is the most common and largest production plastic, a kind of thermoplastic resin. The dielectric strength is approximately 2KV/mm. A higher pcf can make a product more expensive, but it can heighten the quality of the product as well. However, one of the most confusing things about foam is the relationship between these characteristics. Expanded Polystyrene (EPS) ... coating has been dried, the foam pattern assembly is positioned on several inches of loose dry sand in a vented flask and additional sand is then added while continuing to vi‐brate the flask until the pattern assembly is completely embedded in sand. 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. Material: Low-Density Range: Medium-Density Range: High-Density Range: Polyfoam: Less than 1.5 PCF: 1.5 PCF to 1.7 PCF: More than 1.7 PCF: Memory foam : Less than 4 PCF: 4 PCF to 5 PCF: More than 5 PCF: Density vs. Firmness and ILD. Generally, neither water nor vapor affects the mechanical properties of EPS. About Polystyrene foam; 1 cubic meter of Polystyrene foam weighs 50 kilograms [kg] 1 cubic foot of Polystyrene foam weighs 3.1214 pounds [lbs] Polystyrene foam weighs 0.05 gram per cubic centimeter or 50 kilogram per cubic meter, i.e. All rights reserved. The cellular structure of molded polystyrene is essentially impermeable to water and provides zero capillary. XPS is a uniform R 5 per inch K) at 10 °C. The EPD applies to 1 m³ and 1 m² with R-value 1 (in EPD Annex) with average density of 20 kg/m³. 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. It has almost same kind of chemical composition as of the EPS but produced with a different kind of technology. The higher the density of the product, then the higher the R-value will be. PROPERTY UNITS Type XI Type I Type VIII Type II Type IX DENSITY (Nominal) Lb/ft3.75 1.00 1.25 1.50 2.00 DENSITY (Minimum) Lb/ft3.70.90 1.15 1.35 1.80 2. This should be taken into consideration when selecting adhesives, labels and coatings for direct application to the product. Intro to Surfboard Foam; Intro to Stringers; Blanks Catalogue 2020; Quick Ref Blanks Chart; Foam Density Chart; So what is Superwhite Foam? In addition, it is resistant to many solvents including styrene and most fuels, yet is compatible with most adhesives and laminating resins. 0000015378 00000 n XPS is another form of a foam which offers improved surface roughness and higher stiffness with reduced thermal conductivity. Man Four different density values of 50 kgmˉ³, 64 kgmˉ³, 80 kgmˉ³ and 100 kgmˉ³ were considered in this study. When you compare EPS and XPS insulation at the same R-values, EPS insulation can be between 10 to 30 percent less expensive and costs about 19 cents per sq.
