In the demanding world of high-performance plastics, durability and resistance to environmental factors are crucial. Ultraviolet (UV) radiation is a major contributor to the degradation of polymers, leading to embrittlement, discoloration, and loss of mechanical strength. Ningbo Inno Pharmchem Co., Ltd. offers UV Absorber UV-360 (CAS: 103597-45-1), a highly effective light stabilizer that provides essential protection for advanced plastic applications.

UV-360, also known as Diurethane Dimethacrylate, is a benzotriazole-based UV absorber. Its primary function is to absorb UV radiation, particularly in the 300-400nm range, and convert it into thermal energy. This process shields the polymer matrix from UV-induced bond breakage, which is the root cause of photodegradation. The efficiency of this mechanism ensures that UV-360 significantly extends the service life of plastic components.

Key Advantages of UV-360 for Plastics

High-performance plastics are often subjected to rigorous conditions, including high processing temperatures and prolonged outdoor exposure. UV-360 excels in these demanding scenarios due to several key properties:

  • Low Volatility: Unlike many other UV absorbers, UV-360 exhibits very low volatility. This means it remains effectively within the plastic matrix even at high processing temperatures or during long-term use in warm environments. This sustained presence is critical for providing consistent and long-lasting UV protection.
  • High Thermal Stability: The ability to withstand high temperatures without degrading is essential for plastics used in automotive parts, electronics, and industrial components that may experience thermal stress. UV-360's inherent thermal stability ensures its effectiveness during manufacturing and in operational use.
  • Broad Compatibility: UV-360 demonstrates excellent compatibility with a wide range of polymers, including polycarbonate (PC), acrylic resins (PMMA), polyesters (PET), polyamides (PA), polyolefins (PE, PP), and styrenic polymers. This broad compatibility allows it to be seamlessly integrated into various plastic formulations without negatively impacting other properties.
  • Resistance to Migration and Precipitation: Its high molecular weight and good compatibility reduce the likelihood of the absorber migrating to the surface or precipitating out of the polymer matrix, ensuring the integrity and appearance of the plastic part over time.

Applications in Advanced Plastic Materials

The versatility of UV-360 makes it an ideal choice for numerous high-performance plastic applications. It is widely used in:

  • Engineering Plastics: Enhancing the weatherability and durability of components used in automotive interiors and exteriors, electrical housings, and industrial machinery.
  • Clear Plastics: Protecting transparent plastics like polycarbonate and acrylics from yellowing and becoming brittle, maintaining clarity and impact resistance.
  • Fibers and Films: Improving the lightfastness and durability of plastic films and fibers used in textiles, packaging, and agricultural applications.
  • Adhesives and Sealants: Ensuring the long-term performance of adhesives and sealants used in construction and manufacturing, protecting them from UV-induced degradation.
