Foam Factory carries sheets of expanded polystyrene in three different densities: 1LB, 2LB, and 3LB. Our polystyrene foam sheets are available for immediate order in a standard size of 24”x48” and thicknesses from 1” to 8” as either a single sheet or a budget-friendly 4-pack.

Polystyrene foam blows in the wind and floats on water due to its low specific gravity. It can have serious effects on the health of birds and marine animals that swallow significant quantities. [71] Juvenile rainbow trout exposed to polystyrene fragments show toxic effects in the form of substantial histomorphometrical changes.

Owens Corning® FOAMULAR® & FOAMULAR® NGX® 250 Extruded Polystyrene (XPS) Rigid Foam Insulation is a closed cell, highly moisture-resistant foam board well suited to meet the insulation needs for a wide variety of residential and commercial building applications.

Polystyrene foam, a derivative of the polymer polystyrene, is a versatile material with unique properties such as low density, insulating capabilities, and shock absorption. Its applications are widespread, spanning packaging, construction, and the food service industry.

Expanded polystyrene can be a budget-friendly option that offers good thermal- and sound-insulating properties. Extruded insulation has great water resistance and is ideal for use in areas like crawlspaces. If you’re interested in insulating with STYROFOAM, note that STYROFOAM insulation is a type of extruded insulation.

There are mainly two types of polystyrene foams: extruded polystyrene (XPS) foam and EPS. Both of them are rigid foams consisting of rigid closed cells and are manufactured by different processes producing products with very different performance properties.

Polystyrene is a lightweight, durable thermoplastic, widely used in solid and foam forms for insulation, packaging, and product manufacturing due to its affordability and versatility. Its forms and properties make it one of the most important polymers used today.

Feb 20, 2024 · Polystyrene insulation is a rigid, closed-cell foam insulation composed of extruded (XPS) or expanded (EPS) polystyrene. This type of insulation is terrible at conducting heat because it literally has millions of air bubbles inside that trap air and prevent it …
