Windshield wiper blade is a very important item on a vehicle as it helps to get a clear vision while driving. Wiper blades are like squeegees. Arms of the wiper drag a thin rubber strip across the windshield to clear away the water.

Materials used for making Windshield Wiper Blades
Wiper blades are usually made of materials that can wipe the windshield more clearly thereby enhancing clarity of vision.

Generally, windshield wiper blades are made of natural rubber. Some windshield wiper blades are also made of mixing rubber with some other compounds like silicone for better strength, resistance to extreme climatic conditions and durability.

Design of Windshield Wiper Blades:
Most of the vehicles have same type of wiper design though there are some exceptions. Most vehicles have two wiper blades that move together to clean the windshield. One of the blades mount from a point to the driver's side of the vehicle and the other mounts from near the middle of the windshield.

The wiper blade should be supported in such a way that even pressure is distributed from all the sides against the windshield.

Wiper blades are generally designed to attach in a single point in the middle, but a sequence of arms branch out from the middle, so the blade is actually connected in six to eight places.

There are different wiper blade schemes used by various vehicles. Some of common designs are:

• Cars using single wiper arm that extends and retracts while seeping across the window.
• Some cars use wiper blades mounted on opposite sides of the windshield and move in opposite direction.
• Cars having single wiper pivoted in the middle.
• Wiper blades usually comes with universal adapters.
