Clariant's comprehensive line of CESA additive masterbatches offers unprecedented opportunities to improve the properties, performance and quality of finished products, while also optimizing productivity and costs.

Oxidation and heat aging are major causes of degradation of plastics. Exposure to heart and oxygen causes a chain reaction involving the formation of free-radicals, which inevitably leads to cleavage of the main chains in the polymer and degradation of the plastic. This is manifested in many difference ways including loss of shine and transparency, yellowing, surface cracking and odors. Oxidation can also result in loss of mechanical properties such as impact resistance, elongation and tensile strength.

CESA-nox antioxidant masterbatches are formulated to combat thermo-oxdative decomposition at every stage of the plastic life cycle, from manufacturing, drying and processing through end use. They are particularly suitable for use in LDPE, HDPE and PP.

One example is CESA-nox 4201, a masterbatch based on a combination of antioxidants for long-term heat protection of polypropylene caused by severe outdoor and/or heat exposure.
