Polymers are ubiquitous in modern life, from automotive components and packaging to construction materials and textiles. However, their susceptibility to degradation by environmental factors, particularly ultraviolet (UV) radiation from sunlight, poses a significant challenge. UV-induced degradation can compromise the aesthetic appeal, mechanical properties, and overall performance of polymeric products, leading to premature failure and increased replacement costs.

Different polymers exhibit varying degrees of sensitivity to UV radiation, and the degradation mechanisms can manifest in several ways.

Common Polymer Degradation Pathways Under UV Exposure:

  • Polycarbonate (PC): PC is known for its clarity and impact resistance but can yellow and become brittle upon prolonged UV exposure. The UV radiation can cleave the carbonate linkages, leading to chain scission and the formation of chromophores that absorb visible light, causing yellowing.
  • Polyethylene Terephthalate (PET): PET, widely used in bottles and fibers, can suffer from a loss of tensile strength and clarity. UV radiation can cause hydrolysis and chain scission, reducing its molecular weight and impacting its mechanical properties and transparency.
  • Polyolefins (PE, PP): Polyethylene (PE) and Polypropylene (PP) are susceptible to photo-oxidation. UV exposure initiates the formation of free radicals, leading to cross-linking or chain scission, resulting in surface cracking, chalking, and loss of flexibility.

The Role of UV Absorber UV-360 in Prevention

To combat these degradation pathways, the incorporation of UV stabilizers is essential. UV Absorber UV-360 (CAS 103597-45-1) is a highly effective solution for protecting a wide range of polymers, including PC, PET, and polyolefins. Its broad-spectrum UV absorption capabilities (300-400 nm) effectively capture and dissipate harmful UV energy, preventing the initiation of degradation reactions. Its low volatility and excellent compatibility ensure that it remains effective throughout the polymer's lifecycle, offering durable protection even under harsh environmental conditions.
