Description

PATENTKRAV 1. Fleksibelt polyurethanskum baseret på methylendiphenylisocyanater og iso-cyanat-reaktive forbindelser, der er valgt blandt polyoler og polyaminer med en gennemsnitlig ækvivalentvægt i intervallet fra 1.000 til 3.000, kendetegnet ved, at forholdet mellem densiteten udtrykt i kg/m3 og kompressionshårdheden ved 40% kompression, målt ifølge fremgangsmåden beskrevet i ISO 3386, udtrykt i kPa, har en værdi på mindst 20, og at densiteten af skummet ligger i intervallet fra over 45 kg/m3 til 200 kg/m3. 2. Fleksibelt polyurethanskum baseret på methylendiphenylisocyanater og iso-cyanat-reaktive forbindelser, der er valgt blandt polyoler og polyaminer med en gennemsnitlig ækvivalentvægt i intervallet fra 1.000 til 3.000, kendetegnet ved, at det har en kompressionshårdhed ved 40% kompression, målt ifølge fremgangsmåden beskrevet i ISO 3386, på mellem 0,95 og mindre end 2,5 kPa med det forbehold, at sådanne skum, som er fremstillet i en lukket form, og som har en kompressionshårdhed på 2 kPa eller mere, er udelukket. 3. Fleksibelt polyurethanskum ifølge krav 1 eller 2, kendetegnet ved, at det er vandopskummet i nærværelse af under 1 vægt% af et halogencarbon-opskumningsmiddel, baseret på den totale formulering. 4. Fleksibelt polyurethanskum ifølge ethvert af kravene 1-3, som er opnået ved en fremgangsmåde i ét trin. 5. Fleksibelt polyurethanskum ifølge ethvert af kravene 1-4, som har en kompressionshårdhed under 2,0 kPa. 6. Fleksibelt polyurethanskum ifølge ethvert af kravene 1-5, som har en kompressionshårdhed under 1,0 kPa. 7. Fleksibelt polyurethanskum ifølge ethvert af kravene 2-6, som har en densitet på over 45 kg/m3. 8. Fleksibelt polyurethanskum ifølge ethvert af kravene 1-7, som har en densitet på mellem 50 og 200 kg/m3.
