Polyurethanes were first discovered in the early 20th century by German chemist, Werner von Siemens. However, it wasn't until the 1950s that polyurethanes began to be developed and commercialized as a class of polymers. Since then, polyurethanes have become an essential material in a wide range of industries, including construction, automotive, furniture, and textiles.
