Bakelite: The Early Plastic Created as an Alternative to Secreted Beetle Resin

Synthetic plastics are a relatively new invention. For hundreds of years, people had been using organic plastics in some form or another. For example, in Medieval Europe, animal horns that had been scraped thin and flattened were used to make translucent windows. Another common plastic derived from natural sources are natural gum rubbers, which was later vulcanized and popularized by Charles Goodyear. As technology progressed, more natural plastics were used to create more products.

Shellac is a resin secreted by the female lac bug on trees in countries like India and Thailand. In the early 20th century, to insulate early electronic devices, the dawning electronics industries in America and Europe were importing shellac by the shipload which was quite costly. So, many companies were looking for cheap alternatives.

In 1907, Leo Henricus Arthur Baekeland (November 14, 1863 – February 23, 1944), a Belgian chemist working in New York, best known for the inventions of Velox photographic paper in 1893, made an extensive study of natural polymers such as the shellac he was attempting to replace. By combining phenol and formaldehyde he created polyoxybenzylmethylenglycolanhydride, a completely synthetic polymer. By subjecting this synthetic polymer to pressure in moulds to force the air bubbles out, he created a smooth and hard plastic – the pervasive early 20th-century plastic called Bakelite, an inexpensive, nonflammable and versatile plastic, which marked the beginning of the modern plastics industry. He has been called “The Father of the Plastics Industry” for the invention of Bakelite.

Black Bakelite Telephone

Bakelite being resistant to electricity, heat, and chemicals, quickly found its way into a countless number of applications. Bakelite has been used to form the bodies of consumer electronics, insulating wires, parts for firearms, brake pads, camera bodies, and importantly the iconic black Bakelite telephones, and more.

At one point during metal shortages created by World War II, the United States government even considered making coins using Bakelite.
