Polyolefins and ABS resins are among the most widely used polymers globally, found in everything from packaging and automotive components to consumer electronics and construction materials. Their versatility, however, is accompanied by a need for effective protection against degradation during processing and throughout their service life. NINGBO INNO PHARMCHEM CO.,LTD offers advanced additive solutions, including our high-performance Antioxidant Blend 215, specifically designed to enhance the stability and longevity of these critical materials. This blend leverages synergistic antioxidant action to maintain melt flow and preserve color, crucial for high-quality output.

Polyolefins, such as polyethylene (PE) and polypropylene (PP), are susceptible to thermo-oxidative degradation. The high temperatures and shear forces involved in processing can initiate free radical chain reactions, leading to chain scission or cross-linking. This can manifest as a loss of mechanical strength, embrittlement, and undesirable changes in melt flow. Similarly, ABS (Acrylonitrile Butadiene Styrene) resins, known for their toughness and rigidity, can suffer from discoloration and a decrease in impact strength when exposed to heat and oxygen during processing. Effective stabilization is therefore essential to maintain their performance characteristics.

Antioxidant Blend 215 is formulated to address these challenges head-on. It combines a primary hindered phenolic antioxidant with a secondary phosphite antioxidant. The hindered phenolic component acts as a radical scavenger, neutralizing the free radicals that initiate degradation. The phosphite component works by decomposing hydroperoxides, which are intermediate products of oxidation that can further propagate the degradation process. This synergistic action provides a comprehensive defense, protecting the polymer matrix from within.

The benefits of using Antioxidant Blend 215 in polyolefin and ABS applications are significant. Firstly, it ensures excellent melt flow consistency. By preventing chain scission and cross-linking during processing, the blend maintains the polymer’s viscosity, leading to more uniform product dimensions, better surface finish, and improved processing efficiency. This consistency is vital for applications requiring tight tolerances, such as injection molded parts or extruded films. Secondly, the blend provides superior color protection. It inhibits the formation of chromophores, which are responsible for yellowing and discoloration in polymers. This ensures that polyolefin and ABS products retain their intended color and aesthetic appeal, which is critical for consumer-facing applications and branded goods.
