PSU-UV
When exposed to prolonged ultraviolet (UV) radiation, standard PSU resin is susceptible to chain scission and yellowing, which compromises its transparency and mechanical properties.
UV-resistant PSU grades are specially formulated by incorporating advanced UV absorbers and light stabilizers, or through copolymerization modification. These treatments significantly enhance the material's resistance to UV radiation and weathering, making it highly suitable for long-term outdoor and semi-outdoor exposure applications.
