Abstract

Det er beskrevet en ikke-tverrbundet skumstruktur med lukkede celler med et forhold mellom minste dimensjon og største dimensjon på 1/8 eller mindre som omfatter en flerhet av koaleserte ekstruderte tråder eller profiler av et polyetylen-skummateriale som har en gjennomsnittlig celle- storrelse på fra 0,02 til 0,5 millimeter. Tverrsnitts- geometrien til skumstrukturen tilsvarer i alt vesentlig det samlede arrangement av åpningene i dysen som polyetylen- skummaterialet blir ekstrudert fra. Det er videre beskrevet en fremgangsmåte for fremstilling av ovennevnte skumstruktur som omfatter å ekstrudere et skumbart polyolefinmateriale gjennom dysen med flere åpninger for å danne strukturen.A closed cell non-crosslinked foam structure having a minimum to maximum dimension ratio of 1/8 or less is disclosed comprising a plurality of coalesced extruded strands or profiles of a polyethylene foam material having an average cell size of from 0.02 to 0.5 millimeters. The cross-sectional geometry of the foam structure substantially corresponds to the overall arrangement of the openings in the nozzle from which the polyethylene foam material is extruded. A process for preparing the above foam structure is further described which comprises extruding a foamable polyolefin material through the multiple aperture nozzle to form the structure.
