The electrical industry relies heavily on the performance and reliability of wires and cables. The insulation materials used in these applications are subjected to constant electrical current, mechanical stress, and varying environmental conditions, all of which can accelerate degradation. NINGBO INNO PHARMCHEM CO.,LTD. provides advanced additive solutions, including specialized antioxidants, to ensure the longevity and safety of these critical components.

Wire and cable insulation materials, often made from polymers like polyethylene (PE), polypropylene (PP), and ethylene-vinyl acetate (EVA), are highly susceptible to thermal and oxidative degradation. This degradation can lead to a loss of dielectric strength, increased brittleness, and ultimately, failure of the insulation. Antioxidants are therefore essential additives that protect the polymer matrix from these damaging effects. Antioxidant 697, with its low volatility and excellent thermal stability, is particularly well-suited for these demanding applications.

The primary function of an antioxidant in wire and cable insulation is to prevent thermal degradation during processing and service life. During extrusion and subsequent operation, the polymer is exposed to heat, which can initiate oxidation. Antioxidants scavenge the free radicals formed, interrupting the degradation cycle and preserving the material's properties. Furthermore, the metal deactivating capabilities of Antioxidant 697 are crucial, as trace metal contaminants from conductors or processing aids can catalyze oxidation. Its role as a polymer stabilizer is vital for maintaining insulation integrity.

The compatibility of Antioxidant 697 with various polymers commonly used in the wire and cable industry, such as PE, PP, and ABS, makes it a versatile choice. When used as part of a comprehensive stabilization package, it can significantly improve the anti-yellowing performance and weather resistance of products. This ensures that cables maintain their electrical performance and physical integrity over extended periods, even when exposed to varying operational temperatures and environmental conditions.

Moreover, the non-discoloring and non-staining nature of Antioxidant 697 is a significant advantage. This ensures that the insulation remains aesthetically pleasing and does not cause any unwanted color transfer to adjacent materials. The focus on high purity antioxidant additive ensures consistent performance and adherence to stringent industry standards.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting the electrical industry with high-performance additive solutions. By understanding the specific challenges faced in wire and cable applications, we help our clients select and implement the most effective stabilization strategies, including the application of antioxidant 697 in wire and cable insulation, to ensure product reliability and safety.
