Polyurethane rollers are often (though erroneously) referred to as urethane rollers. Urethane is a synonym for ethyl carbamate, which is not actually an ingredient of polyurethane. In other words, polyurethane and urethane are two completely different materials. However, in conversations about elastomeric materials, both words are frequently used in reference to the same material. That material, polyurethane, is characterized by its strength and its elasticity, which contribute to its durability and shock resistance when applied as a roller.
The discovery of polyurethanes is attributed to Otto Bayer in the year 1937 when he was working with coworkers at the laboratories of I.G. Farbenindustrie A.G. in Germany. The first polyurethane was formed from the reaction between a diamine-forming polyurea and an aliphatic diisocyanate. The polyurea was later replaced by glycol due to the enhanced properties of the polyurethane created.
Due to the fact that polyurethane is lightweight, has low production cost, and has exceptional physical properties, the polyurethane is adaptable to a variety of industrial uses. The urethane parts have noise abatement, chemical resistance, abrasion resistance, excellent cut and tear properties. Some of the many parts made with cast urethane are: gears, sprockets, bumpers, rollers, automotive mounts, seals and many more items.
