CIRCULUM® Standard grades​

CIRCULUM® B- and K-grades are white, high quality EPS raw materials.

Whether you are producing insulation or packaging products, from the wide product range of BEWiSynbra RAW you will find the right raw material for your process.

Grades for frost insulation/perimeter applications are also available, as well as low pentane grades.

 

Properties

Circulum B- and K-grades are expandable polystyrene for 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.

B-grades have been optimized for packaging and especially for fish boxes, but K-710 grades and smaller are also successfully used in packaging applications. For insulation applications K-grades are recommended, but B-580 and bigger grades can also be used.

Both Circulum standard grades are compliant with the compositional requirements of the major food contact regulatory regimes in Europe.
