InVento Optima 500FR/PL and 800FR/PL is expandable polystyrene (EPS) based on innovative athermal additive, with a low thermal conductivity value. The materials was produced using recycled materials. Materials have a form of grey spherical polystyrene particles that contain a new type of flame retardant pFR (without HBCD) and low level of hydrocarbon as a blowing agent. Their surface is coated to support processing and to prevent electrostatic charge. Due to the content of halogenated flame retardant the product is unsuitable for objects intended for direct contact with food.

APPLICATION
InVento 500FR/PL can be molded on both shape and block molding equipment. It can be used to produce blocks at medium to high density with very low thermal conductivity, which is cut to make insulation board. It may also be used for contour moldings with a wall thickness >10mm, such as molded building elements and specialist packaging.
