Silicone: Driving the evolution of automotive technology

Silicones are high-performance polymers that exhibit properties of both inorganic and organic compounds. Silicones have a multitude of characteristics including heat resistance, cold resistance, weatherability, water repellency, defoaming properties, adhesiveness, releasability and dielectric properties. Silicone products are used in numerous ways to improve safety and reliability, and to make automobiles smaller, lighter and more eco-friendly. Silicones are critical to the evolution of automotive technology, and manufacturers are taking notice.
