Neopor
Neopor is a foam based on polystyrene . The name is a registered trademark of BASF .
In addition to polystyrene and the blowing agent pentane, the balls of the raw granulate contain a proportion of ground graphite . Under the influence of heat, a characteristic silver-gray foam is created. This foam is marketed in the form of blocks, panels or molded parts.
The graphite particles should scatter the heat radiation and thus reduce the transport of thermal energy within the material. An insulation board with a bulk density of 15 kg / m³ has a thermal conductivity of 0.032 W / (m · K). Compared to expanded or extruded polystyrene, better thermal insulation is achieved with less raw material . Only half of the raw materials are required for the same insulation performance; a Neopor sheet can be up to 30% thinner or 50% less dense than a conventional polystyrene sheet. Neopor thus enables the formation of leaner constructions and the saving of insulating plastic.
