HS321 , is one of the TPC Performance expandable polystyrene products range. It 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.

 HS321 is specially high strength formulated to achieve low density foam without lumps during pre-expansion. This grade is not fire retardent ,so it is not suitable for bulding applications.
