Foams made of Styropor® and its innovative counterpart, Neopor®, help make energy efficient building and construction a reality. Insulating materials made by BASF are at the forefront of sustainable construction and offer advantages over other materials in terms of cost-effectiveness, preservation of resources and environmental consideration. The return on investment for insulating materials is usually short and contributes to retaining and even enhancing the value of buildings.

Building and Construction


Styropor® and Neopor® EPS is valued for its outstanding thermal insulation properties and provides the highest cost efficiency per inch of thermal insulation when compared to other rigid insulation materials. Properly installed, it resists aging, is free from the tendency to rot or degrade and yet is compatible with traditional building materials and their components, including cement, lime, polymer dispersions, water, acid and alkalis (although it must be protected from solvents and their vapors).


Rigid insulation board produced from BF and BFL grades of Styropor EPS and all grades of Neopor EPS except P 5200 can be used in most construction or insulation applications when installed in accordance with Code. EPS foam insulation can be produced to provide a wide range of performance properties. It should be ordered in accordance with ASTM C 578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation, in whatever size and density is necessary to meet the requirements of the application.


EPS foam can be laminated to a variety of other materials to provide composite insulation for a wide assortment of applications.




Styropor® foam is a widely used packaging material including inserts, box-type packs, composite moldings, crates and trays for foodstuffs, transport and display pallets thanks to the following physical and chemical attributes listed below.


These same attributes apply to Neopor® foam, except Neopor® foam has up to 20% lower thermal conductivity. Neopor® foam is an excellent choice when more space for contents is desired in the package or when the contents of the package need to be kept cooler - or warmer - for a longer period of time. Neopor P 5200 EPS is produced without a flame retardant, making it ideal for packaging applications.


  • low density for lightweight packaging
  • high energy absorption when dropped or subjected to impact
  • abrasion-resistant yet relatively soft surfaces protect packaged goods against dirt and damage
  • low thermal conductivity protects contents against sudden temperature changes
  • as the foam is unaffected by water and water vapor, its mechanical properties remain intact
  • chemically inert, so that it can be used for food packaging
  • easy to mold into almost any shape which helps the packaging designer
