Silicone refers to the rubber element of the wiper blade. Silicone is known in baking to withstand extreme heat conditions, but it also performs in extreme cold. Michelin silicone wipers are tested from -80⁰F to +195⁰F and passed the real world use test in a world record breaking drive from Alaska to Argentina experiencing all weather climates. Michelin features Quadtech™ 4-layer coated silicone that provides enhanced durability, flexibility, quite performance and water repellency, lasting 2X longer than standard blades.
