Abstract

Oppfinnelsen er rettet mot et flyteelement for å holde garn og fangsredskaper flytende. Det blir også beskrevet en prosess for fremstilling av slike flyteelementer. Flyteelementene blir fremstilt i en endoterm prosess der det benyttes spesielle blandingsforhold mellom forskjellige plastmaterialer som for eksempel polypropylen, sammen med et blåsemiddel. Flyteelementene har en spesiell densitet som gjør at de har gode oppdriftsegenskaper, men er også robuste mot sprekking og kollaps ved bruk på store havdyp.The invention is directed to a floating element for keeping nets and fishing gear afloat. A process for manufacturing such floating elements is also described. The floating elements are manufactured in an endothermic process where special mixing ratios are used between different plastic materials, such as polypropylene, together with a blowing agent. The floating elements have a special density which means that they have good buoyancy properties, but are also robust against cracking and collapse when used at great depths.
