CIRCULUM® Flame retardant grades
CIRCULUM® NF-grades are white, high quality EPS raw materials with polymeric flame retardant.
Whether you are producing flame retardant insulation or packaging products, BEWiSynbra RAW can provide you with a suitable raw material for your process and application.
Properties
Circulum NF-grades are 100 % HBCD free expandable polystyrene for flame retardant shape moulding and block moulding applications, consisting of free-flowing spherical beads and containing pentane as expanding agent. Bead size range from about 0.5 mm up to 2 mm is available to cover all applications from thin-walled and detailed products to light insulation boards. Grades for frost insulation/perimeter applications are also available.
All NF-grades fulfill the requirements of class E according to EN 13501-1.
