The visual and functional quality of flexible Polyvinyl Chloride (PVC) is often marred by surface imperfections such as 'fish eyes'. These small, translucent defects can significantly impact the aesthetic appeal and performance of PVC products. NINGBO INNO PHARMCHEM CO.,LTD. addresses this challenge with its specialized additive, Antioxidant 245 (CAS 36443-68-2), which has proven effective in fish eye reduction during the processing of flexible PVC.

Antioxidant 245, a high-performance phenolic antioxidant, not only protects polymers from degradation but also plays a crucial role in improving processing characteristics. In the context of flexible PVC, its ability to mitigate fish eye formation is a key benefit. Fish eyes typically arise from incomplete plasticization or dispersion of PVC particles and additives within the polymer matrix. Antioxidant 245 aids in achieving a more homogeneous blend and smoother melt, thereby minimizing the occurrence of these undesirable defects.

By promoting better dispersion and enhancing the overall stability of the PVC compound during high-temperature processing, Antioxidant 245 contributes to a more uniform surface finish. This is critical for applications where appearance is paramount, such as in clear films, sheets, or coatings. The low volatility and excellent color stability of Antioxidant 245 ensure that it remains effective throughout the processing cycle without contributing to discoloration or plate-out issues, which can exacerbate surface defects.

For manufacturers of flexible PVC products, such as flooring, medical tubing, or packaging films, the use of Antioxidant 245 offers a clear advantage. Achieving a defect-free surface finish directly translates to higher quality products and increased customer satisfaction. Understanding the specific dosage and synergy with other plasticizers and stabilizers is key to maximizing its effectiveness in fish eye reduction. Companies looking to source this critical additive can rely on NINGBO INNO PHARMCHEM CO.,LTD. for consistent quality and technical guidance.

The integration of Antioxidant 245 into flexible PVC formulations represents a targeted approach to overcoming common processing challenges. Its contribution to smoother surfaces and improved aesthetics, alongside its inherent antioxidant properties, makes it an indispensable component in modern flexible PVC manufacturing. As the demand for high-quality, visually appealing PVC products grows, the role of specialized additives like Antioxidant 245 becomes even more pronounced.
