BEWiSynbra Circulum® GF-514p Expandable Polystyrene
Categories: Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)

Material Notes: Description: GF-514p is a flame retardant (FR) expandable polystyrene grade, containing graphite, with reduced thermal conductivity. Pentane is used as a blowing agent and a brominated polymeric flame retardant as an FR additive. The product is delivered in the form of spherical beads with a bulk density of about 0.6 g/cm3 and is available in 1100 kg octabins.

Applications: The properties of GF-514p make it suitable for the production of flame retardant light and heavy insulation board by block or shape moulding, in accordance with ISO EN 11925-2 class E.
