Rubber is available in a variety of forms for industrial, manufacturing, and protective applications. Rubber sheets, strips, and rolls are used in gasket manufacturing or to protect equipment. Rubber cord stock is often used as custom seals. Rubber rods are fabricated into rubber parts and used for sealing and cushioning applications. They are thicker and shorter than rubber cords. Rubber tubes are used to insulate wires, cables, and other kinds of sensitive equipment. Rubber balls are used as seals or on the inside of vibrating sifters to help clean screens in food, beverage, and pharmaceutical applications.
