The biggest difference is the different materials of the wiper strips. The most common rubber windshield wiper blades are mainly made of natural rubber and carbon black, which are vulcanized at high temperature and then sprayed with lubricating materials on the surface. The main material of silicone coated wiper strips is modified silicone, but the production process is similar to that of rubber wipers, except that the added silicone component will continue to adhere to the glass during the work of the wiper to form a layer of silicone oil film, which will reduce the tension on the glass surface, so that rainwater cannot stay and directly forms water droplets and slides away.
Rubber Windshield Wiper Blades are quieter than silicone wipers, because silicone coated wipers must add silicone oil that can gradually precipitate into the silicone strip to achieve the coating effect, which will increase the friction between the wiper and the glass. In addition, silicone itself is soft, so the friction is greater than that of rubber. Therefore, as long as the glass is slightly dirty, silicone wipers will easily produce friction noise.
However, relatively hard natural rubber will be much better. For example, the patented silent technology wiper of Hidden Wing adopts a patented support buffer design, which allows the angle between the rubber strip and the glass to maintain a low friction state for a longer time, so that the Rubber Windshield Wiper Blades work more smoothly and avoid unnecessary noise.
