Natural antioxidants as stabilizers for polymers
Natural antioxidants (AO) can be divided into two main groups, namely enzymatic and non-enzymatic antioxidants .Enzymatic antioxidants either catalyze directly the decomposition of reactive oxygen species to harmless compounds (catalase, superoxide dismutase enzymes) or regenerate non-enzymatic antioxidants (glutathione reductase, glucose-6-phosphate dehydrogenase) .
A brief introduction of the commonly used antioxidant
A wide range of rubber antioxidant , function each different. According to its main function can be divided into oxygen resistance aging agent, antiozonant, harmful metal ions inhibitors, resist fatigue agent, uv absorber, resistance to cracking agent. But, since each kind of protection function often is not a certain kind of rubber antioxidant purpose-built, most of several factors can rubber
Beyond this, the rubber compound will become “saturated” with the antidegradant and the excess chemical will “bloom” to the surface. This is when synergy between antidegradants can help. If using three (3) phr of antioxidant “A” does not provide the needed protection, a second antioxidant “B” can be added to the rubber compound
mixing. The benefit of this method would allow the protective chemical(s) to: 1) react with oxygen that was entrained in the rubber compound as a result of mechanical mixing and 2) would bleed toward the surface over time; offering a continuous supply of protection for the rubber article.These chemicals became known as “ Antioxidants”.
