The primary benefits of butyl rubber are superior gas/moisture impermeability, weather resistance, ozone, flexibility and vibration dampening. These properties make it an excellent choice for durable inflatables, innerliners for tires, inflatable sporting goods, aquatic liners and a variety of mechanical products.
Butyl is generally not recommended for contact with petroleum oils and liquids.
