Abstract (en)

[origin: US4488979A] A hydraulic fluid which contains 100 parts by weight of polyisobutylene, 3 to 15 parts by weight of butylstearate and 0.5 to 5 parts by weight of palm seed oil. It shows good compatibility with newly rolled aluminum surfaces and is therefore particularly suitable for feeding hydrostatic means of supporting rolls for roll-forming aluminum and aluminum alloys.

Abstract (de)

Die Hydraulikflüssigkeit enthält 100 Gewichtsteile Polyisobutylen, 3 bis 15 Gewichtsteile Butylstearat und 0,5 bis 5 Gewichtsteile Palmkernfett. Sie zeigt eine gute Verträglichkeit mit frisch gewalzten Oberflächen von Aluminium und ist deshalb insbesondere geeignet zur Speisung von hydrostatischen Stützquellen von Walzen für das Walzverformen von Aluminium und Aluminiumlegierungen.
