Aging of automobile parts

The aging of automobile parts refers to the phenomenon that the original performance of the automobile parts such as rubber, plastic products and electronic components gradually declines with time. Such parts and products will occur regardless of work or not, such as rubber tires, plastic devices and other long-term storage will crack, harden and other aging symptoms.

Aging means that during the use of polymer materials, due to the combined effects of environmental factors such as heat, oxygen, water, light, microorganisms, and chemical media, the chemical composition and structure of polymer materials will undergo a series of changes, and physical properties will also occur. Correspondingly, such as hard, sticky, brittle, discolored, losing strength, etc. These changes and phenomena are called aging. The essence of aging of polymer materials is the change of their physical structure or chemical structure.
