Physical Properties
| Method | Unit | Value | |
|---|---|---|---|
| Compressive Strength<sup>2</sup> | ASTM D1621 | psi, min. | 25 |
| Water Absorption<sup></sup> | ASTM C272 | % by volume, max. | 0.3 |
| Water Vapor Permeance<sup>3</sup> | ASTM E96 | perm, max | 1.5 |
| Maximum Use Temperature<sup></sup> | - | ¡ã¹ó | 165 |
| Coefficient of Linear Thermal Expansion<sup></sup> | ASTM D696 | in/in?¡ã¹ó | 3.5 x 10-5 |
| Flexural Strength<sup></sup> | ASTM C203 | psi, min. | 50 |
2Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam? Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation. For static loads, 3:1 is suggested. For dynamic loads, 10:1 is suggested.
