Expanded polystyrene foam (or EPS) is a closed cell, resilient, lightweight rigid cellular plastics material produced in a range of densities between 13.5 kg/m3 and 28 kg/m3. The grades of expanded polystyrene we keep in stock are SL, M, H and VH grade.
Features
EPS foam has many features such as:
- Closed cell lightweight cellular plastics foam produced from polystyrene
- Material has been modified by the addition of flame retardant additives
- Gains excellent insulating properties from the stabilised air trapped within its cellular structure
- Contains no CFCs or any other gas that can escape to harm the ozone layer or decrease its insulation properties
- Highly resistant to the negative effects of moisture content
- Exceptional flotation properties
- Can withstand the effects of changes in temperature, thereby providing longevity in low temperature applications
- Impervious to vermin or pests, including termites
- Cost effective when compared to other insulating foams
- Polystyrene can be painted with non-solvent based paints
Applications
The main applications for products manufactured from EPS foam are:
- Thermal insulation systems (wall, roof and sub-floor)
- Ceiling panels and other decorative surfaces
- Concrete voids and block outs
- Pipe insulation
- Protective packaging
- Flotation and buoyancy applications
- Stage sets
