Abstract
A találmány eljárást szolgáltat tömör külső réteggel és lágy cellásmaggal rendelkező lágy, de legfeljebb félkemény poliuretán formázotttermékek előállítására, mely szerint a) szerves és/vagy módosítottszerves poliizocianátokat és/vagy poliizocianát előpolimereketreagáltatnak b) legalább egy poliol komponenssel, melynek OH száma 20-200, funkcionalitása 2-6, előnyösen 2-3, c) adott esetben olyan poliolkomponenssel együtt, melynek OH száma 201-899, és funkcionalitása 2-3,és d) legalább egy lánchosszabító komponenssel, melynek OH vagy aminszáma 600-1850, funkcionalitása 2-4, és e) adott esetben ismertadalékokkal, aktivátorokkal és/vagy stabilizátorokkal víz és1,1,1,3,3-pentafluorbutánt és legalább egy további fluoralkánttartalmazó habosítóanyag keverék jelenlétében. Az eljárás lényege aspeciális, nem éghető, fluoralkánt és 1,1,1,3,3-pentafluorbutánt (R365mfc) tartalmazó habosítóanyag-keverék alkalmazása. A találmánytárgyát képezik az eljárással előállított formadarabok is, melyeknektömbsűrűsége 150-900 kg/m3 valamint a formadarabokat tartalmazókülönféle késztermékek, elsősorban kerékpárnyergek, biztonságiszelepek, kartámaszok, fejtámlák, kormányborítások,motorkerékpárnyergek, egészségügyben használt székek.
