This is a fire retardant molding grade typically used for medium-density foam applications. It consists of spherical polystyrene particles (beads) containing an expanding agent, pentane and an internal flame retardant additive. Applications: This is a fire retardant molding grade. It is used for the producing block at medium densities, which are subsequently cut into board. Compared with standard Styrocell grades, EF443C offers more controllable pre-expansion, short maturing times and fast cycle time during molding. This grade should not be used for food contact applications. Information provided by NOVA Chemicals. |
