Elastomer covered rolls touch nearly every aspect of our world, helping to make the products we rely on where we work, live, and play. Printing, graphic arts, pulp & paper, steel & aluminum, textiles, and plastics are a few of the industries that rely on rubber rollers. In turn, the roller market uses the widest array of elastomers in the rubber industry.
The purpose of the elastomer roll covering is to create a uniform pressure zone, referred to as a “nip.” To assure that the nip remains constant, the right properties must be in the compound for the elastomer covering to keep it stable and not degrade during use over time.
Therefore, the selection of the elastomer for the roll covering must consider the physical properties of the covering and how the elastomer will perform in the roller application. An effective elastomer covering must not change appreciably during use and must stand up to challenging environments with harsh solvents and chemicals. Different environments require elastomers with specific physical properties.
