As a fully integrated manufacturer, Goodyear Rubber is equipped to formulate custom compounds specifically designed for your application.

Silicone rubber is an elastomer different from other rubbers in that it has an inorganic backbone made of silicon and oxygen atoms. Organic rubbers have a carbon-carbon chain atomic structure. The outstanding physical property of silicone is its’ retention of flexibility and tensile strength at relatively high and low temperatures, from -150 F to 600 F. Silicones are very flexible due to large bond angles and bond lengths compared to basic organic polymers. Silicone rubber is a material of choice where retention of shape and mechanical strength are desired under heavy thermal stress or sub-zero temperatures. Silicone rubber is highly inert and does not react with most chemicals and due to its structural properties, it is widely used in aircraft engine parts, door and window sealing parts, healthcare and medical applications including implants.
