FC522 is a free flowing expandable polystyrene grade, consisting of spherical polystyrene beads containing pentane as the expansion agent. Expandable polystyrene (EPS) is normally expanded to achieve the low densities required for final step expansion. The typical density of this grade is around 25 kg/m3, but other densities are possible depending on applications and equipments. FC522 is specially fast cycling and water proof formulated to achieve low density foam without lumps during pre-expansion. This grade is not fire retardant so it is not suitable for building applications. Applications: High Density Block, Shape Molding.Information provided by Tabriz Petrochemical Commercial Co. |
