What is the density of expanded polystyrene?

What is the density of expanded polystyrene?

Polystyrene Foam (EPS) Physical Data Sheet

1LB Polystyrene
Density (LB/Cubic Ft.) 1.02
Thermal Resistance (R-Value @ 1″ Thick) @ 25°F / @ 40°F / @ 75°F 5.56 / 5.26 / 4.70
Compressive 10% Deformation (PSI) 46
Flexural (PSI) 99

What is high density EPS?

High Density (HD) Envirosheet is a high density economical foam board insulation made from Expanded Polystyrene (EPS) offering a high R-value per dollar. It is a highly durable and cost-effective product that is primarily designed to be used for below grade applications for residential or commercial construction.

What is the difference between Styrofoam and expanded polystyrene EPS foam?

As we said, Styrofoam™ is a Dow trade, blue in color, and is an extruded polystyrene (XPS) foam made for thermal insulation, construction and craft applications. EPS is an expanded polystyrene available in various densities for insulation, construction and craft applications and so much more.

How is EPS foam density measured?

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. If a product has a 3LB density, that means its 12″ x 12″ x 12″ block weighed 3LB.

Does expanded polystyrene absorb water?

A: EPS is non-hygroscopic and does not readily absorb moisture from the atmosphere. Its closed-cell structure reduces the absorption and/or migration of moisture into the insulation material.

How do you find EPS density?

In Imperial or US customary measurement system, the density is equal to 0.94 pound per cubic foot [lb/ft³], or 0.00867 ounce per cubic inch [oz/inch³] ….The entered volume of Expanded Polystyrene (EPS), Type I in various units of volume.

centimeter³ 1
inch³ 0.06
liter 0
meter³ 1 × 10-6
metric cup 0

What is the strongest Styrofoam?

Duramate™ Plus is a Styrofoam™ Brand extruded polystyrene (XPS) foam insulation, designed for residential home construction. It is DuPont’s strongest XPS foam insulated sheathing, with proprietary extra-tough plastic on both sides.

What are the different uses of polystyrene?

  • What is the specific heat capacity of polystyrene?

    Styrofoam is a material that is made of expanded polystyrene foam (EPS). It is generally used to make food containers, coffee cups etc. The specific heat capacity of Styrofoam is calculated experimentally as 0.27calgm−1oC−1 or 1131Jkg−1K−1.

    Why to use polyurethane foam?
