Abstract

PURPOSE: To prepare a closed-cell highly foamed polyolefin article having smooth surface, easily, by quenching an extruded and foamed polyolefin resin composition containing specific foam shrinkage controlling agent and a volatile foaming agent.
CONSTITUTION: A polyolefin resin is compounded with (A) 0.1W10 wt% of a foam shrinkage controlling agent selected from the compounds I, II, III, etc. (R1,3 are 10W24C hydrocarbon group; R2,4,5 are H, 1W24C hydrocarbon group; n1 is 1W22; R13 is 9W23C hydrocarbon group; R14,15 are H, 1W22C hydrocarbon group) and (B) ≥5 wt% of a volatile foaming agent having a boiling point of lower than the melting point of the base resin. The composition is kneaded, extruded and foamed. At the completion of the foaming, and when the surface temperature of the foamed article is still above the softening point of the resin, the surface is quenched to a temperature lower than the extrusion and foaming temperature by ≥5°C, to obtain a polyolefin resin foamed article having a density of 8W10 kg/m3.
