For manufacturers working with polymers that undergo high-temperature processing, selecting the right UV absorber is paramount to ensure product longevity and performance. Degradation caused by ultraviolet (UV) radiation can lead to discoloration, loss of mechanical properties, and ultimately, product failure. This is where advanced UV absorbers, such as the high molecular weight hydroxyphenyl benzotriazole class, become indispensable.

At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical role these additives play. Our focus is on providing solutions that not only offer superior UV protection but also withstand demanding processing conditions. One such product, UV Absorber 234 (CAS 70321-86-7), stands out for its exceptional performance in high-temperature applications.

Understanding the Challenge of High-Temperature Processing

Polymers like polycarbonates, polyesters, polyacetals, polyamides, and certain engineering plastics are often processed at temperatures exceeding 200°C. During these stages, traditional, lower molecular weight UV absorbers can volatilize, leading to a significant loss of protective capability and potential issues in the processing equipment itself. This necessitates the use of UV absorbers with inherently low volatility.

The Advantage of UV Absorber 234

UV Absorber 234 is specifically designed to address these challenges. Its high molecular weight contributes to its low volatility, meaning it stays within the polymer matrix even at elevated processing temperatures. This ensures sustained UV protection throughout the product's intended lifespan, maintaining its original color and mechanical integrity. Its chemical structure, a hydroxyphenyl benzotriazole, allows it to efficiently absorb harmful UV radiation in the 300-400 nm range, converting it into harmless thermal energy.

Key Applications and Benefits for Buyers

Procurement managers and R&D scientists looking to buy UV Absorber 234 will find it invaluable for a range of applications:

  • Engineering Plastics: Enhance the UV resistance of components used in automotive, electronics, and construction industries where durability is key. When you purchase UV Absorber 234, you invest in longer-lasting products.
  • Films and Fibers: Its low volatility makes it ideal for thin-film applications and fibers, where surface area is high and consistent protection is vital. You can source this essential plastic additive from a reliable manufacturer.
  • Molded Articles: Protect consumer goods, outdoor furniture, and industrial parts from UV-induced degradation, maintaining their aesthetic appeal and structural integrity.

The typical use levels for UV Absorber 234 range from 0.15% to 0.60%, depending on the specific polymer and desired performance. It can also be effectively used in combination with other stabilizers, such as hindered amine light stabilizers (HALS) and antioxidants, to achieve synergistic effects and optimize outdoor performance.
