Fire retardant expanded Polystyrene SABIC® EPS550FF is manufactured by the suspension polymerization of styrene monomer. The polymerization is
generally carried out in a batch process and it contains a fire retarding additive in the formulation. SABIC® EPS550FF is an expandable polystyrene grade
supplied in free-flowing beads containing pentane (CFC free) as a foaming agent.
SABIC® EPS550FF grade is used for shape molding with wall thickness greater than 10 mm and for block molding with medium-to-high density for thermal
insulation in construction industry. SABIC® EPS550FF has retarded ignitability and the moldings made from it will conform to the requirement of DIN
53438 class K1 and K2.
