Antioxidant mixtures
Caused by the influence of oxygen and oxygen compounds, polymers generally are subject to oxidation. Impairment through thermal stress, especially at higher processing temperatures can cause problems. These problems mostly occur when mixing of two or even more polymers with different permissible processing temperatures.
With our HECONOX® product range we provide a number of highly effective antioxidants, mostly primary and secondary antioxidants for the plastics processing industry.
In general, the decomposition reaction is a chain reaction. The majority of primary antioxidants are sterically hindered phenols or secondary amines which are considered as so-called scavengers. Secondary antioxidants are almost exclusively found in sulfur compounds and act by corroding the hydro peroxides. HECOPLAST® uses extremely effective antioxidants which saturate and stabilize the hydro peroxide reaction beginning already at 120°C.
Oxidation is shown in loss of gloss or transparency as well as a tendency to yellowing, in impairing the mechanical and physical properties. In principle, the aging process cannot be stopped but can be significantly delayed and because of that the above mentioned thermal processing properties as well as the useful properties will be improved or at least retained over a longer period of time.
