Extruded polystyrene foam board compressive strength.

Astm c578 type vi. Styrofoam is the trade name of a range of blue extruded polystyrene foam insulation boards originally developed and marketed by the dow chemical company in the early 1940 s. Polystyrene blocks eps. The products are organized left to right in ascending compressive strength.

Compressive and flexural strength values for expanded polystyrene are based on short term load conditions in accordance with typical astm test standards. Extruded polystyrene is a closed cell polystyrene rigid foam board with high compressive strength and excellent long term thermal resistance performance. As do most load bearing building materials eps foam insulation products creep under long term continuous load conditions and in critical applications this characteristic must be considered. It is produced on a continuous fully automated extrusion process.

Unlike expanded polystyrene eps styrofoam is manufactured via a continuous extrusion process. 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. Extruded polystyrene xps rigid foam insulation owens corning foamular 250 extruded polystyrene xps rigid foam insulation is a closed cell highly moisture resistant rigid foam board well suited to meet the needs for a wide variety of residential and commercial construction applications. Celfort and foamular extruded polystyrene insulation boardsare suitable for all types of high strength construction applications the boards are lightweight durable and impact resistant which helps to reduce job site damage foam insulation can be scored and fabricated easily with common hand tools.
