FIELD: production methods.
SUBSTANCE: method includes the stage of extrusion of foamed mix through the drawhole, which contains thermoplastical polymer and foamed addition in fluxed condition, for realizing the foaming. Then it is made the cooling and cutting the foam material at the input from drawhole by knife, during this procedure it is made the cooling by fluid.
EFFECT: it is generated the method of achieving the granules on the base of foamed polymer with solid-core layer.
