Standard Material Available

· Polyester base TDI: This is our standard base of urethane. It has high resistance to cutting, tearing, chunking and oils. This material is best for most urethane applications.
· Polyether base TDI: This material is used for high speed and load bearing applications. It also resists attack by water.
· Polyester and polyether base MDI: This material is used for higher temperature applications. It is also good for food grade applications.
· Sure-Grip TM: All of our polyester base TDI rolls are cast from the Sure-Grip TM formula. This formula adds more friction to the roll surface without sacrificing other physical properties.

Standard Finishes Available

· Ground finish: This is the most common finish given for a urethane roll cover. This finish is achieved in our grinding operation using a smooth grit grinding stone. Grind finishes can be polished (#1 ground finish), smooth or standard (#2 ground finish) and rough ground (#3 ground finish).
· Directional crepe finish: This is a finish developed by universal Urethane primarily for bridle roll applications or where having a non-slip surface is important. The finish resembles crepe paper bumps and the skin of an orange. Crepe finishes are applied directionally, meaning your roll grips significantly better running with the crepe than against it. When crepe finish is specified, the direction of the roll must also be specified. Crepe finishes can be smooth - like an orange peel (#1 crepe finish), medium (#2 crepe finish) or very rough (#3 crepe finish).
· Non-directional crepe finish: This finish is the same as the crepe finish, except there is no direction applied to the crepe. This finish is needed if a roll can be used in any direction or when it is not feasible to run the roll in one direction. Non-directional crepe finishes can be smooth (#1 non-directional crepe finish) medium (#2 non-directional crepe finish), or very rough (#3 non-directional crepe finish).
· Saw-cut finish: This finish is used in such applications as belt pulleys and conveyor rolls. It is rougher than ground finish, smoother than crepe finish and has a woven grain look. Saw-cut finishes can be smooth (#1 saw-cut finish), regular (#2 saw-cut finish), and rough (#3 saw-cut finish).
