polymer degradation

Polymer degradation is the process where plastics and similar materials break down into smaller parts or lose their properties over time. This can happen due to exposure to sunlight, oxygen, water, or heat, which cause chemical reactions that weaken the polymer chains. As these chains break, the material becomes brittle, discolors, or loses its flexibility. Degradation can be natural, like aging or weathering, or accelerated by environmental factors, leading to the eventual breakdown of the material. Understanding this process is important for managing the lifespan of plastic products and developing more durable, eco-friendly materials.
