The challenge of protecting polymers from UV radiation is compounded when dealing with high-temperature processing techniques. Many standard UV absorbers can volatilize or degrade under these conditions, reducing their effectiveness. For manufacturers seeking robust UV protection, identifying a suitable additive is crucial. Our UV Absorber 234 (CAS 70321-86-7) stands out as a premier solution, specifically engineered for these demanding scenarios.

The High-Temperature Processing Dilemma
Processes like extrusion, injection molding, and blow molding often involve temperatures exceeding 200°C. During these stages, additives with low molecular weight or high vapor pressure can be lost from the polymer melt. This loss not only diminishes the UV protection performance but can also contribute to extruder fouling and processing difficulties. Therefore, procurement managers and formulation chemists must prioritize UV stabilizers with inherently low volatility and high thermal stability.

UV Absorber 234: A Superior Choice
UV Absorber 234, a high molecular weight hydroxyphenyl benzotriazole, addresses these challenges effectively. Its molecular structure imparts a high degree of thermal stability and low volatility, making it an exceptional choice for polymers processed at elevated temperatures. As a manufacturer and supplier, we are proud to offer this advanced UV absorber that:

  • Maintains Integrity at High Temperatures: Its low volatility ensures it remains within the polymer matrix during processing, providing consistent UV protection throughout the product's lifecycle.
  • Offers Broad UV Absorption: Efficiently absorbs UV radiation in the 300-400 nm range, safeguarding sensitive polymers from photodegradation.
  • Ensures Excellent Compatibility: It integrates well with a wide array of polymers, including Polycarbonates (PC), Polyesters (PET, PBT), Polyamides (PA), and Polyolefins (PE, PP), facilitating seamless incorporation into existing formulations.
  • Delivers Minimal Color Impact: Its inherent low color contribution ensures that the aesthetic properties of the final product are preserved.

Applications Benefiting from UV Absorber 234
When you decide to buy UV Absorber 234, you are opting for reliability in critical applications such as:

  • Automotive Components: Interior and exterior parts requiring long-term exposure resistance to sunlight.
  • Electrical and Electronic Housings: Protecting sensitive components from UV-induced yellowing or embrittlement.
  • Construction Materials: Enhancing the durability of films, sheets, and profiles used in building applications.
  • Packaging: Protecting contents of transparent or translucent packaging from UV damage.
