In the demanding world of polymer science, ensuring the long-term performance and aesthetic appeal of plastic materials often hinges on the inclusion of specialized additives. Among these, UV absorbers play a crucial role in shielding polymers from the damaging effects of ultraviolet radiation. For applications that require robust UV protection, especially in environments exposed to sunlight or artificial UV sources, UV Absorber 234 (CAS 70321-86-7) emerges as a highly effective solution.

NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer UV Absorber 234, a premium-grade additive designed to meet the stringent requirements of modern plastic formulations. As a leading manufacturer and supplier in China, we understand the technical challenges faced by R&D scientists and product formulators.

What Makes UV Absorber 234 Stand Out?

UV Absorber 234 belongs to the hydroxyphenyl benzotriazole class, known for its excellent UV light absorption capabilities. Its key characteristics include:

• High Molecular Weight and Low Volatility: This is a significant advantage for polymers processed at high temperatures. Unlike lower molecular weight absorbers that can evaporate during compounding or molding, UV Absorber 234 remains largely within the polymer matrix, ensuring sustained protection. This makes it ideal for applications involving polycarbonate, polyesters, polyamides, and other engineering plastics that require high processing temperatures.
• Broad UV Spectrum Coverage: It exhibits strong absorbance in the UV-A and UV-B regions (300-400 nm), effectively preventing photo-oxidation and degradation pathways that can lead to material failure.
• Excellent Compatibility: UV Absorber 234 demonstrates good compatibility with a wide array of polymers, including PVC, styrene homo- and copolymers, thermoplastic polyurethanes, and more. This ease of incorporation simplifies formulation development.
• Minimal Color Impact: The product has minimal absorbance in the visible light spectrum, meaning it contributes very little to the initial color of the polymer, a critical factor for clear or lightly colored applications.

Applications for Procurement and R&D Professionals

When seeking to buy UV Absorber 234, formulators can target several key application areas:

• Automotive Components: Enhancing the durability and appearance of interior and exterior parts exposed to sunlight.
• Building and Construction: Protecting window profiles, roofing materials, and facade elements from UV-induced weathering.
• Consumer Goods: Ensuring the longevity and visual appeal of products like electronics housings, outdoor furniture, and appliances.
• Films and Fibers: Providing crucial UV protection in agricultural films, packaging, and synthetic fibers used in textiles and outdoor gear.

The typical recommended use level for UV Absorber 234 is between 0.15% and 0.60% by weight, depending on the polymer type, processing conditions, and the intended service environment. It can also be synergistically combined with other additives like Hindered Amine Light Stabilizers (HALS) for enhanced performance.
