Expanded Polystyrene Foam Density

It is usually white and made of pre expanded polystyrene beads.

Expanded polystyrene foam density.

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 in design calculations. Foam types polystyrene foam standard sizes 96 x48 and 48 x24 thicknesses 1 to 32 in one inch increments can be cut to any thickness up to 32 thick.

Tds expanded polystyrene doc page 2 of 4 what is expanded polystyrene eps eps is a closed cell lightweight cellular plastics material produced from polystyrene.

Polypropylene coated sheets have an added layer of moisture protection. Eps foam is perhaps the most common in everyday life. Polystyrene literally translated is polymerised styrene. Contact us for details.

Expanded polystyrene or eps geofoam is a cost efficient insulation material used in the construction industry. Rigid polystyrene foam insulation sheets these sheets resist the absorption of water air and gas and are widely used in cold storage and packaging applications. The thermal conductivity of expanded polystyrene foam of density 20 kg m 3 is 0 035 0 037 w m k at 10 c. A versatile building material it works well for a variety of different applications such as road construction bridge abutments slope stabilization building foundations retaining walls stadium and theatre seating fill for.

Expanded polystyrene insulation is a lightweight rigid closed cell insulation. Eps foam is the correct term for any form of expanded polystyrene. Granules are heated with steam in such a way that they are rapidly expanding foaming and forming a low density block in a special form. This closed cell structure provides minimal water absorption and low vapor permanence.

Expanded polystyrene eps is a rigid and tough closed cell foam with a normal density range of 11 to 32 kg m 3. It is extremely lightweight but strong and durable. Eps is used for food containers molded sheets for building insulation and packing material either as solid blocks formed to accommodate the item being protected or as loose fill peanuts cushioning fragile items. Eps is available in several compressive strengths to withstand load and back fill forces.

The material has been modified by the addition of flame retardant additives.
