What is the term used for fine cracks that may extend in a network over or under the surface of transparent plastic enclosures?

The term used for fine cracks that form in a network pattern over or beneath the surface of transparent plastic enclosures is known as crazing. Crazing occurs when the material is subjected to stress or strain, which causes small fractures to develop. These cracks often create a visually distressing pattern while still maintaining the integrity of the overall structure. The phenomenon is commonly observed in various types of plastics, especially those exposed to environmental factors such as UV light, chemicals, or mechanical impacts.

Fracturing typically refers to more significant breaks or splits in a material, which is distinct from the subtle and often interconnecting nature of crazing. Weathering describes the degradation of materials due to atmospheric conditions over time but does not specifically refer to the cracking pattern. Peeling generally refers to a layer of material coming off from a surface rather than the formation of cracks. Understanding these distinctions is essential when assessing the condition of transparent plastic enclosures and determining appropriate maintenance or replacement strategies.
