The automotive industry places stringent demands on the materials used in vehicle manufacturing. Plastic components, in particular, must withstand a wide range of environmental conditions, including heat, UV radiation, and exposure to various fluids, while maintaining their structural integrity and aesthetic appeal. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced antioxidant solutions to meet these challenges, ensuring the longevity and performance of automotive parts.

Automotive plastic components are exposed to significant thermal stress, especially in the engine bay and under direct sunlight. This heat can accelerate oxidative degradation, leading to embrittlement, cracking, and loss of mechanical properties. Antioxidants play a crucial role in mitigating these effects by scavenging free radicals and interrupting the degradation chain reactions. Antioxidant 697, known for its excellent thermal stability and low volatility, is a key additive for enhancing the durability of automotive plastics.

Beyond thermal stress, automotive parts are also exposed to UV radiation, which can cause photo-oxidation and discoloration. While Antioxidant 697 primarily functions as a thermal antioxidant and metal deactivator, it is often used in conjunction with UV stabilizers and HALS (Hindered Amine Light Stabilizers) to provide comprehensive protection. This combined approach ensures that plastic components maintain their mechanical properties and appearance even after prolonged exposure to sunlight. The ability to contribute to improving weather resistance of polymers is critical in this sector.

Furthermore, the metal deactivating properties of Antioxidant 697 are beneficial in automotive applications where trace metal ions from catalysts or wear particles might be present. By complexing these metal ions, it prevents them from catalyzing degradation, further enhancing the overall stability of the plastic components. Its efficacy as a metal deactivator for polyolefins and other engineering plastics commonly used in automotive applications is well-established.

The compatibility of Antioxidant 697 with various polymers used in the automotive industry, such as ABS, PP, and EPDM, makes it a versatile solution. Its non-discoloring nature is also advantageous, ensuring that components like interior trim pieces and under-the-hood parts maintain their original appearance. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing the automotive sector with high-quality additives that contribute to vehicle safety, reliability, and aesthetics, including specialized formulations for antioxidant 697 polymer stabilizer needs.

In summary, advanced antioxidants are indispensable for the automotive industry. By providing robust protection against thermal, oxidative, and photo-degradation, additives like Antioxidant 697 help ensure that automotive plastic components perform reliably under demanding conditions, contributing to longer vehicle lifespans and enhanced occupant safety.
