F400 is an EPS class with HBCD flame retardant, which can be used in production of EPS foam in density ranges above 20 kg/m3 suitable for shape molding with good fusion and surface finish.
F400 in general is used for small parts and thin wall with good surface finish is used for cases and packaging product, insulation application which is requiring fire classification, in industrial applications inside proton brick with impact absorber and for light concrete applications.
Lower densities can be achieved after multiple expansion
