For B2B clients in the plastics industry, the procurement of essential additives like UV stabilizers is a strategic decision that impacts product quality and market competitiveness. Understanding the nuances of products like UV-328 is key. NINGBO INNO PHARMCHEM CO.,LTD., a dedicated manufacturer and supplier, offers a detailed look at why UV-328 (CAS# 25973-55-1) is a preferred choice and how to secure it effectively.

Chemical Profile and Performance Advantages of UV-328

UV-328 is a highly effective UV absorber belonging to the benzotriazole family. Its chemical structure allows it to efficiently absorb UV radiation in the critical 270-340 nm spectrum. This property makes it an excellent guardian for polymers against photodegradation. Key performance indicators that make UV-328 attractive to manufacturers and formulators include:

• Superior UV Light Absorption: Its primary benefit is its ability to absorb a broad range of UV light, preventing the chain scission and cross-linking that weaken polymers.
• Excellent Compatibility: UV-328 exhibits good solubility and compatibility with numerous polymer matrices, including polyolefins, polyesters, PVC, and styrene-based polymers, ensuring uniform distribution and consistent protection.
• Low Volatility: This characteristic is crucial during melt processing, as it minimizes the loss of the additive, ensuring the intended protection level is maintained in the final product.
• High Washing Resistance: For applications that involve contact with liquids or cleaning processes, UV-328’s resistance to leaching ensures its efficacy is not compromised.

Market Applications and Sourcing Considerations

The versatility of UV-328 makes it suitable for a wide range of applications. Whether you are formulating automotive components, outdoor furniture, agricultural films, or packaging materials, UV-328 offers the protection needed to maintain product integrity and aesthetic appeal. Its performance is often compared favorably to similar UV absorbers like UV-326 and UV-327, but with enhanced compatibility and low thermal evaporation, making it a cost-effective solution for many industrial needs.

Key Specifications and Usage Recommendations

UV-328 is typically supplied as a yellowish powder or granule. Its physical properties, such as a melting point of 79-87°C, low ash content (≤0.1%), and low loss on drying (≤0.5%), underscore its quality. Recommended dosages vary by polymer, generally between 0.1% and 0.5%. For example, recommended levels for polyethylene (PE) are 0.2-0.4%, and for polycarbonate (PC), it's 0.15-0.3%. We encourage customers to consult our technical data sheets (TDS) and material safety data sheets (MSDS) for comprehensive handling and application guidance.
