Expanded Polystyrene, commonly known as EPS foam in North America, is a lightweight, closed-cell, semi-rigid and highly insulating cellular plastic based material. Comprised mostly air, EPS foam exhibits physical and mechanical properties rendering it an excellent choice of material for numerous industries and applications, especially for insulation in construction projects, protective insulating packaging for food and general packaging products offering high impact protection for sensitive contents.
Expanded Polystyrene is the perfect solution for a broad range of industries including:
Construction
Public Infrastructure (roads, bridges, etc.)
Television & Film
Automotive
OEM (Original Equipment Manufacturers)
Expanded Polystyrene, commonly known as EPS in North America, is a light weight, closed-cell, semi-rigid cellular plastic material. EPS exhibits physical and mechanical properties which render it as an excellent choice of material for several industries and applications.
Expanded Polystyrene has many desirable physical and mechanical properties such as:
Superior long term thermal resistance
EPS is an inert material and is dimensionally stable
Excellent Buoyancy
Excellent moisture resistance
Light weight and easy to handle
High compressive strength relative to its weight
Versatile material and can be molded or cut into a multitude of shapes and forms
100% recyclable
Ozone friendly. Does not use CFC’s or HCFC’s in the manufacturing process
Cost effective with a relatively Low cost per R-value (R-value is a measure thermal insulation)
Construction
The majority of EPS production in North America is used in the construction industry in several applications including:
High density EPS insulation panel products
Thermal insulating material for exterior/interior below and above grade walls and roof structures
Thermal insulating material of floors and slab on grade
Main substrate material for stucco and exterior insulating finishing systems (EIFS)
Thermal insulation for radiant floor heating
Insulated concrete forms (ICF’s) for walls and floors
Structural insulated panels (SIP’s)
Garage door insulation
Geofoam
Due to its light weight, dimensional stability and high compressive strength, a special grade of EPS referred to as geofoam is used in geotechnical applications including:
Retaining wall backfill
Road construction and widening
Bridge abutment and underfill
Culverts, pipelines and buried structures
Noise and vibration damping
Slope stabilization
Stadium and theatre seating
Under slab fill for ice rink floors
Landscaping and green roofs
Automotive
The automotive industry is another innovative application of EPS products. Automotive manufacturers have for the past decade increased their usage of EPS in the exterior and interior of several components to make cars and trucks lighter, more fuel efficient yet safe and stylish to attract more revenue from clients. EPS is now commonly used in automotive components such as:
Behind bumpers
Body side moldings
Dashboards
Under seat cushions
Behind door trims and arm rests
Recreational Themes
EPS has also proved its cost effectiveness for recreational themes. Due to its light weight and production versatility, EPS is used in the recreation industry to create monuments, historical building replicas and decorations. EPS can be molded, hand carved or custom cut with precision to create almost any shape as required. Furthermore several EPS shapes can be glued together easily to form larger objects. The final shape is then painted and/or coated to create the required theme without resorting to the use of heavy materials such as stone or cement or expensive skilled labor such as master masons.
Lost Foam
EPS is also used to create complex and precision metal shapes using a special technique known as lost foam casting. This process requires making the required metal shape in EPS. The EPS shape is then coated with refractory coating and placed in a casting flask that is filled with compacted sand. Molten material is then poured into the casting flask causing the EPS to vaporize leaving behind the required shape in precision cast metal. This is a cost effective method of creative precision metal shapes compared to the traditional wax casting.
