Abstract

Polymer composition comprising a heterophasic propylene copolymer, talc, an organic antioxidant, and a triazine derivative.

Description

technical field [0001] The present invention relates to a novel polypropylene composition containing phenolic antioxidants and the use of triazine derivatives in such polymer compositions. Background technique [0002] Polypropylene is the material of choice for many applications. For example, polypropylene in combination with talc can be used as the back cover of blister packs and in automotive interior articles. The polypropylene / talc compositions generally have good processability and can be individually made to order. However, the material must also provide long-term stability against environmental influences such as oxidative degradation, keeping the tailored properties of the polypropylene / talc composition at expected levels. Therefore, antioxidants are added to reduce degradation of polypropylene / talc compositions. Over the past few years, the standard requirements for long-term stability have steadily tightened, which in turn has increased the amount of additives ...
