Fenómeno del problema
Outdoor PMMA turns yellow and light transmittance decreases after a period of use.
Análisis de la causa
UV radiation and heat-humidity jointly cause PMMA surface microcracks and oxidation.
Solución
Use weather-resistant grade PMMA (containing UV absorber); surface protective coating.
Conclusión clave
PMMA weather resistance is the key to outdoor applications.
