Antioxidants

Antioxidants are an important part of Schäfer Additivsysteme's product portfolio. For the polymer and lubricant industry, antioxidants are a crucial building block for the formulation of long-lasting products. By choosing the right antioxidant, the foundation can be laid for the stabilisation of the respective system.

Antioxidants in the polymer industry specifically slow down undesirable oxidative decomposition processes, which can lead to discolouration and even loss of usability of plastics. Antioxidants also protect against thermally induced ageing and thus serve as process stabilisers during plastics processing. Antioxidants act as radical scavengers or reducing agents.

Antioxidants of the LUBIO® AO series are suitable for use in a variety of polymers such as polyesters, PU/TPU or PVC. The product portfolio of primary and secondary antioxidants for use in plastics includes low- and high-molecular phenolic antioxidants, phosphite-based antioxidants and aminic antioxidants. We also offer complex and synergistic AO systems.

LUBIO® AO 40 rounds off our product portfolio. As a natural antioxidant based on renewable raw materials, LUBIO® AO 40 is the environmentally friendly option for a wide range of applications. LUBIO® AO 40 is suitable for use in polyolefins (PE, PP), bio-based polyesters (PLA, PBS, PCL) and natural rubber (NR).

Antioxidants are indispensable in plastics and lubricants as they inhibit degradation through oxidation. This chemical reaction can cause materials to lose their properties and shorten their service life. The addition of antioxidants protects against premature failure and maintains performance over a longer period of time. This is particularly important in applications that are exposed to high temperatures, UV radiation or other aggressive environmental conditions. The use of antioxidants therefore helps to improve product quality, cost efficiency and sustainability.
