Antioxidant AO-20 is a highly efficient primary antioxidant for polymers.
Its chemical structure includes three sterically hindered phenolic groups.
It functions mainly as a "radical scavenger" it reacts efficiently with peroxy radicals, thus slowing down the chain reaction process which facilitates thermal oxiidation.
Antioxidant AO-20 offers the following performance advantages:
- High Processing and Long-Term Heat Stabilization.
- Low Volatility in the range of temperatures normally used for processing and service of polymers.
- High Compatibility with a wide range of polymers, in particular polyolefins
- High Compatibility and Synergism with a broad range of additives used in formulations of polyolefins and other polymers(in particular with secondary antioxidants).
- High Resistance to leaching in water.
- High Resistance to Heat Treatments, such as "tentering" or "latexing".
- High Resistance to Gas Fading caused by urban and industrial pollution agents such as nitrogen oxides. |
