New perspectives through the discovery of polyurethanes

An invention by the chemist Otto Bayer — who is not related to the family that founded the Bayer Group — revolutionizes the chemical industry, but his discovery is by chance. After mixing two chemical substances, Otto Bayer succeeds in synthesizing the first polyurethane foam. Initially nobody has an idea what it can be used for, and it will take another ten years of development work before customized materials can be manufactured from polyurethanes.
Nevertheless, the chance discovery lays the foundation of the high-tech material supplier that Covestro is today.
