Description
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 different 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. 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.
