InSphere F/NL type 300F/NL, 400F/NL, 500F/NL, 800F/NL and 1600F/NL is expandable polystyrene (EPS) with improved insulation properties, the materials have a form of white spherical polystyrene particles that contain a new type of flame retardant pFR (without HBCD) and a hydrocarbon blowing agent. Their surface is coated to support processing and to prevent electrostatic charge. Due to the content of halogenated flame retardant and the residual blowing agent, the product is unsuitable for objects intended for direct contact with food.

APPLICATION
InSphere 400F/NL can be moulded on both shape and block moulding equipment with improved Insulation properties. It can be used to produce well fused blocks at low and medium densities, which can be cut to make insulation and construction products. It may also be used for large contour mouldings for building & construction applications. Other applications include elastified board for impact and airborne sound insulation, floor elements.
