Abstract

The present invention relates to the use of a combination of additives comprising at least two of the following compounds: - an antioxidant (A) according to formula (I): wherein R 1 , R 2 , R 3 , R 4 and R 5 independently are H, or non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise heteroatoms, - an antioxidant (B) according to formula (II): wherein o R 6 , R 7 and R 8 independently are non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise OH-groups; —‹ X 1 , X 2 , and X 3 independently are H or OH, with the provisio that at least one of X 1 , X 2 and X 3 is OH; and o the entire molecule does not comprise an ester group; and, - carbon black; for reducing taste and / or odour in a polyolefin composition.

Description

technical field [0001] The present invention relates to the use of a combination of two or more components selected from carbon black and one or more antioxidants for reducing taste and / or odor in polyolefin compositions. Background technique [0002] The development of taste and odor in plastic materials is known to be due to chemical degradation or transformation associated with the compounding of plastic materials to produce taste and odor emitting substances. These substances can have very different chemical properties. Even relatively low levels of these taste and odor producing substances can lead to disadvantages in plastic products, since humans are generally highly sensitive to taste and odor. Levels as low as one or a few ppb units are sufficient for a taste or odor to be noticeable. Therefore, to overcome or at least reduce this smell and taste, people have tried in various ways, for example, venting plastic products. These attempts are less effective and, more...
