Tabriz HS221 Performance Expandable Polystyrene
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)
Material Notes:	HS221 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 22 kg/m3, but other densities are possible depending on applications and equipments. HS221 is specially high strength formulated to achieve low density foam without lumps during preexpansion. This grade is not fire retardant so it is not suitable for building applications. Applications: Medium Density Block. Low- and medium-density foam blocks made from HS 221 are used as thermal insulation boards for construction applications without special requirements concerning flame resistance or as packaging blanks.
