Acrylonitrile Butadiene Styrene (ABS) is a popular thermoplastic known for its toughness, rigidity, and impact resistance, making it a versatile material for automotive components, electronic housings, appliances, and consumer goods. However, ABS is susceptible to degradation when exposed to ultraviolet (UV) radiation, which can lead to discoloration, surface cracking, and loss of mechanical properties. To ensure the long-term performance and aesthetic appeal of ABS products, particularly those used outdoors or in high-light environments, incorporating effective UV protection is essential. NINGBO INNO PHARMCHEM, a trusted supplier of specialty chemicals, highlights the benefits of UV Absorber 329 for ABS applications.

The primary challenge with ABS and UV exposure lies in the butadiene component, which is particularly prone to photo-oxidative degradation. UV radiation initiates a cascade of reactions that can lead to the formation of chromophores, causing yellowing, chalking, and embrittlement of the ABS matrix. This degradation not only affects the visual appearance but also significantly compromises the structural integrity and impact strength of the final product.

To counteract these effects, UV absorbers are incorporated into ABS formulations. These additives work by absorbing UV light and converting it into heat, thereby shielding the polymer from damaging radiation. The ideal UV absorber for ABS should possess strong UV absorption capabilities, good thermal stability for processing, excellent compatibility with the ABS matrix, and low volatility to prevent loss during manufacturing. Furthermore, resistance to migration is crucial to ensure continuous protection throughout the product’s lifecycle.

UV Absorber 329 (CAS: 3147-75-9), chemically known as 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol, is a highly effective benzotriazole UV absorber that is well-suited for ABS applications. It offers robust UV protection across a broad spectrum, low volatility, and excellent compatibility with ABS, ensuring it integrates seamlessly into the polymer matrix without compromising its properties. As a premier manufacturer and supplier in China, NINGBO INNO PHARMCHEM provides this critical additive to enhance the durability of ABS products.

For procurement professionals looking to buy UV Absorber 329, its combination with Hindered Amine Light Stabilizers (HALS) offers a synergistic approach to UV protection. While UV absorbers shield the material by absorbing light, HALS work by trapping free radicals formed during degradation. This dual mechanism provides superior long-term stability, significantly improving the weatherability and lifespan of ABS components. This is particularly important for automotive parts, outdoor equipment, and consumer electronics that require sustained performance.
