Abstract
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.
