  "id": "MLC-T-CHM-012662",
  "term": "Weathering",
  "field": "Chemistry",
  "definition": "The physical and chemical degradation of a polymer material due to exposure to outdoor environmental elements. This process involves the combined effects of solar radiation, temperature fluctuations, humidity, rain, and atmospheric pollutants. Weathering can lead to changes in a polymer's mechanical properties, appearance, and chemical structure, often resulting in embrittlement or discoloration.",
