The development of plastics has a long history, starting with the use of natural materials with intrinsic plastic properties, such as rubber, amber, horn, and tortoise shell. By heating and moulding these substances, early humans created a variety of objects. The first synthetic polymer was invented in 1869 by John Wesley Hyatt, who treated cellulose derived from cotton fibre with camphor to create a plastic that could be crafted into various shapes and imitated natural substances. However, the first fully synthetic plastic was Bakelite, invented in 1907 by Leo Baekeland. Since then, numerous new plastics have been developed, leading to an explosion of new forms, with mass production beginning in the 1940s and 1950s.

What You'll Learn
The first synthetic polymer was invented in 1869
Hyatt's ingenuity led him to treat cellulose derived from cotton fibre with camphor, resulting in a remarkable breakthrough. He created a plastic that could be crafted into various shapes and mimic natural substances like tortoiseshell, horn, linen, and ivory. This invention, known as celluloid, revolutionized manufacturing by freeing it from the limitations of nature. For the first time, humans could create materials that were not constrained by the scarcity of natural resources.
Celluloid's versatility and low cost contributed to its widespread adoption. It found extensive use in the production of table tennis balls and film for a significant period. However, its high flammability eventually led to its obsolescence. Despite this, Hyatt's work laid the foundation for further exploration and development in the field of synthetic polymers.
The creation of synthetic polymers marked a significant shift in human history, leading to the Plastics Age in the 20th and 21st centuries. The mass production of plastics began in the 1940s and 1950s, with polystyrene and polyvinyl chloride being among the earliest examples of new polymers. The development of plastics has revolutionized various industries, including medicine, computing, and transportation, by providing lightweight, durable, and inexpensive materials.

Bakelite, the first fully synthetic plastic, was invented in 1907
The world witnessed a revolutionary creation in 1907 with the invention of Bakelite, the first fully synthetic plastic. This innovation marked a significant shift in human history, ushering in what is now known as the Polymer Age or the Age of Plastics. The brain behind this creation was Leo Baekeland, a chemist who was already wealthy due to his invention of Velox photographic paper. Baekeland's journey towards creating Bakelite began with his quest to find a replacement for shellac, a natural electrical insulator that was in limited supply due to its natural source. Shellac was essential for insulating electrical cables during the early 20th century, a time when the United States was rapidly electrifying.
Baekeland's initial experiments involved soluble resins, and he eventually developed a phenol-formaldehyde shellac called Novolak, which, however, did not achieve commercial success. Undeterred, he continued his endeavours and, in the summer of 1907, shifted his focus to strengthening wood by impregnating it with a synthetic resin. On June 18, 1907, he commenced a new laboratory notebook, meticulously documenting his experiments with applying a phenol and formaldehyde mixture to various pieces of wood. Baekeland's perseverance led to a groundbreaking discovery: by controlling the pressure and temperature applied to phenol and formaldehyde, he created a hard, mouldable material—Bakelite.
Bakelite was not just a good insulator; it possessed a range of desirable characteristics. Its durability, heat resistance, and suitability for mechanical mass production set it apart from other materials. Baekeland recognised its potential, marketing it as "the material of a thousand uses." Indeed, Bakelite could be shaped or moulded into almost anything, igniting endless possibilities. The success of Bakelite inspired major chemical companies to invest in the research and development of new polymers, leading to the emergence of new plastics.
The creation of Bakelite had far-reaching implications, freeing people from the constraints of natural resource scarcity and making material wealth more accessible. It contributed to the development of computers, cell phones, and lifesaving advances in modern medicine. Additionally, the lightweight nature of plastics helped conserve fossil fuels in heating and transportation. The impact of Bakelite extended beyond its practical applications, as it sparked a revolution in the chemical industry, which, until then, primarily focused on cloth dyes and explosives.
The term "plastic" itself derives from the Greek word "plastikos," meaning mouldable. Plastics are synthetic or semi-synthetic materials composed primarily of polymers, which are large molecules formed by joining smaller molecules called monomers. The defining characteristic of plasticity allows plastics to be moulded, extruded, or pressed into a diverse array of solid forms. This adaptability, coupled with their low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use worldwide.

Plastic's industrial landscape was significantly impacted by World War I
The first synthetic polymer was invented in 1869 by John Wesley Hyatt, marking the beginning of the Plastics Age. However, the plastics industry only began to take off after World War I, with mass production starting in the 1940s and 1950s.
During World War I, there was a need for durable, inexpensive, and lightweight materials that could be manufactured quickly. This prompted the development of new forms of plastics and improvements in chemistry. The creation of synthetic materials helped free people from the social and economic constraints imposed by the scarcity of natural resources. Inexpensive plastics made material wealth more accessible and improved the standard of living.
One of the earliest plastics was Parkesine, invented by Alexander Parkes and patented in 1862. It was a cheap and colourful substitute for ivory or tortoiseshell. However, it was Leo Baekeland who invented Bakelite in 1907, the first fully synthetic plastic. This opened the door for the creation of new polymers, including polystyrene, polyvinyl chloride (PVC), polyethylene, and nylon.
After World War I, there was a surplus of materials used to make plastics, new manufacturing plants, and a booming economy. Plastic manufacturers worked with women's magazines to promote plastic home goods. Products like Tupperware and polyethylene from DuPont became popular, signalling a shift in consumer perception of plastic. Plastic was now seen as a material with its own unique appearance and texture, and its domestic convenience reflected the aspirations of a casual life of leisure.
The plastics industry in the United States experienced significant growth between 1946 and 1960, with plastic surpassing aluminium in production by 1960. Injection moulding and thermoforming technologies allowed goods to be produced quickly and affordably, making luxury items more accessible to people worldwide. By replacing natural materials with plastic, manufacturers could create products that were cheaper, lighter, safer, and stronger.

Plastic's development started with natural materials
The development of plastics started with natural materials that exhibited plastic properties. Centuries before the Common Era, people were already harnessing the plastic properties of materials like rubber, amber, horn, and tortoise shell. By heating and molding these substances, they created a diverse range of objects. These early plastics were of natural origin, meaning they were derived from non-fossil raw materials (such as oil) and required minimal processing.
In the 19th century, as chemistry developed during the Industrial Revolution, many new materials were reported. The development of plastics accelerated with Charles Goodyear's 1839 discovery of vulcanization to harden natural rubber. Alexander Parkes invented Parkesine, which was patented in 1856, and is considered the first manufactured plastic. It was a cheap and colourful substitute for ivory or tortoiseshell.
John Wesley Hyatt, inspired by a New York firm's offer of $10,000 for anyone who could provide a substitute for ivory, invented the first synthetic polymer in 1869. By treating cellulose derived from cotton fiber with camphor, Hyatt discovered a plastic that could be crafted into a variety of shapes and made to imitate natural substances.
In 1907, Leo Baekeland invented Bakelite, the first fully synthetic plastic, meaning it contained no molecules found in nature. It was durable, heat-resistant, and ideally suited for mechanical mass production. Bakelite could be shaped or molded into almost anything, providing endless possibilities.
The mass production of plastics began in the 1940s and 1950s, with polystyrene and polyvinyl chloride being among the earliest examples of new polymers. The availability of petrochemicals made plastics affordable, and their adaptability, combined with a wide range of desirable properties, led to their widespread use around the world.
Today, plastics are essential to modern life, enabling the development of computers, cell phones, and most of the lifesaving advances of modern medicine. They have raised the standard of living and made material abundance more readily available. However, there are also concerns about the environmental impact of plastics, with some scientists attempting to make plastics safer and more sustainable through the development of bioplastics.

Early plastics were bio-derived materials
The first synthetic polymer was invented in 1869 by John Wesley Hyatt, who treated cellulose derived from cotton fibre with camphor to create a plastic that could be crafted into a variety of shapes and made to imitate natural substances. This discovery was revolutionary as, for the first time, human manufacturing was not constrained by the limits of nature. However, early plastics were bio-derived materials such as egg and blood proteins, which are organic polymers.
In around 1600 BC, Mesoamericans used natural rubber for balls, bands, and figurines. Treated cattle horns were used as windows for lanterns in the Middle Ages. Materials that mimicked the properties of horns were developed by treating milk proteins with lye. In the nineteenth century, as chemistry developed during the Industrial Revolution, many new materials were reported. The development of plastics accelerated with Charles Goodyear's 1839 discovery of vulcanization to harden natural rubber. Alexander Parkes invented Parkesine, considered the first manufactured plastic, in 1855, and patented it the following year. It was a cheap and colourful substitute for ivory or tortoiseshell but did not bring him commercial success.
The world's first fully synthetic plastic, Bakelite, was invented in 1907 by Leo Baekeland, who coined the term "plastics". Bakelite was durable, heat-resistant, and ideally suited for mechanical mass production. The creation of Bakelite marked a significant shift towards synthetic plastics, and by the 1940s and 1950s, mass production of plastics was well underway.
Today, most plastics are produced from natural gas and petroleum. However, there is a growing trend towards bioplastics, which are made from renewable biomass sources such as plant crops instead of fossil fuels. Bioplastics have the potential to make plastic production more sustainable and environmentally friendly. Examples of bioplastics include cellulose bioplastics, polyhydroxyalkanoates (PHA), and OleoPlast, which is made from ethyl cellulose and vegetable oils.
