In 1907, a chemist was chasing a shellac substitute when a hard resin changed the age of plastic

Innovations that transform whole sectors do not necessarily arise from big ideas; rather, they can emerge from problems that seem quite humble in their conception. In 1907, Belgian-born American chemist Leo Baekeland was seeking an artificial substitute for shellac, which was commonly used in paints, electrical equipment, and various manufacturing processes.

Shellac was favored by industry but had inherent constraints inherent to nature. Baekeland thought that a solution could be found through chemistry. The invention he discovered, however, went beyond just finding an alternative to shellac. Instead, he found Bakelite, a synthetic hard resin that would become the first fully synthetic plastic.

A search for a better industrial material

Baekeland started researching in response to an industrial need for practical materials, not a plastics revolution; industries required dependable insulators and coatings that would remain consistent in performance under difficult conditions. While materials like shellac served well, they lacked consistency due to biological unpredictability, among other factors. According to a review in The Royal Society of Chemistry, Baekeland’s research originated from a quest to create synthetic substitutes for natural resins. During this process, he discovered the phenol-formaldehyde chemistry, which had been studied before but had not been developed into anything practical at the time. While Baekeland did not invent the chemical reaction in question, he discovered how to control it.


The historical artifacts gathered at Cornell University put his inventions into context, as the era witnessed a rise in attempts by manufacturers to synthesize their goods rather than gather raw materials from nature. At that time, inventors had already been conducting experiments to find ways to produce goods that could be mass-manufactured, rather than those obtained from natural sources. Baekeland’s work was definitely part of this trend despite the unexpected result it yielded. His search for an alternative to the varnish evolved into something much more important.

The resin that changed manufacturing

The product developed by Baekeland became known as Bakelite; it was a phenol-formaldehyde resin with strength, thermal stability, and electrical insulating properties. As described in the Royal Society of Chemistry review, Baekeland is regarded as the father of phenolic resins, and his work of 1907 is regarded as the start of the practical realization of this type of material, which affected production for decades to come. However, what made Bakelite unique was not only its synthetic nature; it also had properties much desired by the industry. In particular, as noted by Syracuse University in its historic guide, it could withstand high temperatures without melting and was an electrical insulator, which made it ideal for electrical applications during the widespread use of telephones, radio communication, and electric power networks.

Innovation archives at Lehigh University reveal an additional factor behind its success: Bakelite’s versatility, affordability, and suitability for mass manufacturing. Bakelite could be molded into any desired shape without affecting the performance. Such features enabled it to quickly shift from research labs to factories and commercialized goods. Its success reflected much more than just the utility of a single type of resin. It indicated that chemistry can be used to invent entirely new substances with desirable properties.

The invention that helped launch the plastics age

The significance of Bakelite is evident not only in its uses but also in the way it revolutionized the approach to manufacturing materials. As noted in the materials history collections at Cornell University, Baekeland invented the first all-synthetic plastic, which differed from previous materials in that it relied on no natural component. This was groundbreaking since, for the first time, industry was blessed with a product created by chemistry rather than biology. The effects of this innovation soon permeated people’s daily lives, with Syracuse University noting the widespread use of Bakelite in radios, telephones, insulators, and home appliances. Consumers might not be aware of its chemistry, but the substance was always present in any object related to modern technology.

Phenolic resins remain significant even over a hundred years later, underscoring the relevance of Baekeland's contributions today. While his discovery does not apply to all types of plastics developed since then, he set an example of what synthetic products were supposed to be – man-made, engineered for functionality, rather than naturally derived materials. This is the reason why the story is interesting. Baekeland did not set out to create the plastics age; what he had in mind was merely to solve an industrial problem at hand. But the outcome was bigger than the problem itself, since a chemist looking for alternatives for shellac ended up developing a hard synthetic resin.
