Engineering | What is Polyurethane?

Poly What? Polyurethane; a material we have all heard of in the material handling industry, but what do we really know about it? In the following, the history of polyurethane and its uses in the material handling industry and other areas will be explored. History Polyurethanes were invented in the 1930's by Professor Dr. Otto Bayer as a much needed replacement for rubber in World War II. Alongside replacing rubber, polyurethane coatings were used for the impregnation of paper and the manufacturing of mustard gas resistant garments, high-gloss airplane finishes, and chemical & corrosion-resistant coatings to protect metal, wood, and masonry.  After the war, polyurethane began to expand to a much larger scale. It started expanding through industrial applications, such as coatings. Today, polyurethane can be found it almost every material.  Polyurethane in Everyday Applications Polyurethane applications include, but are not limited to: Thread in apparel Rigid foams
