Plastic
In the early 1900’s, shellac was the material of choice when it came to insulation, but due to the fact that it was made from Southeast Asian beetles, the material was not cheap to import. For this reason, chemist Leo Hendrik Baekeland thought he might be able to make some money by producing an alternative. What he came up with, however, was a moldable material that could be heated to extremely high temperatures without being distorted, also known as plastic.
