GENERAL DESCRIPTION & EXTERNAL LINKS
Antioxidant is a substance added in small quantities to hydrocarbons which are susceptible to oxidation, such as rubbers, plastics, foods, and oils to inhibit or slow oxidative processes, while being itself oxidized.  Antioxidants work in two different ways. In primary antioxidants (also called free-radical scavengers), antioxidative activity is implemented by the donation of an electron or hydrogen atom to a radical derivative. These antioxidants are usually hindered amines (p-Phenylene diamine, trimethyl dihydroquinolines, alkylated diphenyl amines) or substituted phenolic compounds with one or more bulky functional groups such as a tertiary butyl at 2,6 position commonly. Butylated hydroxytoluene (BHT) is a common example of hindered phenolic antioxidant. The reaction rate, or carbocation stability, in SN1 mechanism is 3° > 2° > 1° > CH3 (no SN1) so, tertiary alkyl moiety exists in lots of phenolic antioxidant compounds. Primary antioxidants are free radical scavengers which combine with peroxy radicals and break autocatalytic cycle. In secondary antioxidants ( also called peroxide decomposers), activity is implemented by the removal of an oxidative catalyst and the consequent prevention of the initiation of oxidation. Examples of peroxide decomposer type of antioxidant are trivalent phosphorous and divalent sulfurcontaining compound such as sulfides, thiodipropionates and organophosphites. Synergistic effect is expected when primary antioxidants are used together with secondary antioxidants as primary antioxidants are not very effective against the degradation by UV oxidation. Sometimes, chelating agents are added to scavenge metal impurities which can initiate decomposition.

Tetrakis(3-(3',5'-di-tert-butyl-4'-hydroxyphenyl) pentaerythritol is a hindered phenolic antioxidant with a wide range of application against themo-oxidative degradation for polymers, synthetic fibers, elastomers, adhesives and waxes without discoloring.

Polymer Stabilizers protect polymers from oxidative damage. They prevent discoloration and cross linking of polymers during progressing and ensure long term properties of the finished articles.
Phenolic Antioxidant(SONGNOX®) is a highly effective, non-discoloring stabilizer for organic substrates which are prone to oxidation, e.g. plastics, synthetic fibers, elastomers, waxes, oils and fats.
Aminic Antioxidant maintain physical and surface properties with good color, excellent anti-scorch, good heat resistance.
Phosphite Antioxidant(SONGNOX®) is used to protect organic polymers which are prone to oxidation, especially during progressing and color stabilizer.

Thioester Antioxidant(SONGNOX®) decomposes and neutralizes hydroperoxides formed by auto-oxidation of polymers.
Hindered Aminic Light Stabilizer(SONGLIGHT®) protect polymers from degradation due to
uv radiation and long term heat aging.
UV Absorber(SONGSORB®) absorbs ultraviolet radiation and through a reversible chemical rearrangement, dissipates the energy as heat.
