    Additives are ubiquitously used in plastics to improve their functionality. However, they are not always desirable in their 'second life' and are a major bottleneck for chemical recycling.

  • antioxidants


    Antioxidants. Antioxidants decelerate undesired oxidative degradation processes in plastics in a targeted manner which can lead to discolourations until the loss of serviceability. Furthermore antioxidants also protect against thermally induced ageing and thus serve as process stabilisers during the plastics processing.

    Classification of Polymer Additives. Polymer additives can broadly be classified as polymer stabilizers or functional agents. Polymer stabilizers are essential to practical use, since they maintain the inherent properties, color, and other characteristics of plastics by preventing the oxidative degradation caused by high temperature during processing, and ultraviolet exposure during use.
