FIELD: polymer materials. SUBSTANCE: method involves mechanical processing of plastic composition containing chemical pore agent in a plastic-processing machine to yield well homogenized molten composition. The latter is then aged under pressure in closed press mold space at temperature superior to decomposition temperature of pore agent. Additives controlling decomposition of pore agent can also be added to plastic composition. EFFECT: maximized number of closed pores in products manufactured from foam plastic. 4 cl, 2 ex
