Abstract

The present invention discloses polyolefin mouldings having excellent stability when in permanent contact with an extraction media, said polyolefin extractions comprising, as stabilizers, a selected mixture comprising an organic phosphite or phosphonite, and a group especially selected from sterically hindered phenols, or a specific group of sterically hindered amines. It is further disclosed a selected three component mixture, comprising a phosphite or phosphonite, a phenolic antioxidant, and a specific group of sterically hindered amines, which is particularly suitable as a moulding stabilizer of polyolefins in permanent contact with extraction media.
