Wiper blades are an essential component of any vehicle, responsible for clearing rain, snow, and other debris from the windshield to ensure clear visibility while driving. They consist of a rubber or silicone squeegee attached to a metal frame, with the squeegee being the primary element that comes into contact with the glass.

Historically, wiper blades were made from natural rubber, but advancements in materials science have led to the development of synthetic rubber compounds that offer improved durability, resistance to ozone and UV radiation, and better wiping performance. These compounds, such as EPDM (ethylene propylene diene monomer) rubber, provide a longer lifespan for wiper blades, reducing the need for frequent replacements.

In addition to the squeegee material, the frame of the wiper blade is typically made from metal, such as steel or aluminum. The metal frame provides support and structural integrity to the blade, ensuring it maintains its shape and applies even pressure across the windshield. Some wiper blades also incorporate additional features, such as aerodynamic spoilers to reduce wind noise or heated elements to melt ice and snow.
