Bakelite®(Phenol Formaldehyde) : The First Synthetic Plastic

Bakelite® changed the world in the first half of the twentieth century.

Advertised with the slogan ‘The material of 1000 uses’, this was the first synthetic plastic and heralded an age in which we were no longer dependent on the products of nature.


The legacy of Bakelite® is a world where synthetic plastics surround us: from medical implants to space shuttles, we have now become dependent on these synthetic materials.

On 7 December 1909, the United States Patent and Trademark Office granted the Belgian-born chemist #LeoBaekeland a patent for a “Method of making insoluble products of phenol and formaldehyde”.

Hard, compact, insoluble and infusible this was the first synthetic plastic. Named #Bakelite® after its inventor.


Leo Baekeland moved from Europe to the United States, starting life in America working for a photographic firm.

An able chemist and innovator, Baekeland developed his own photographic paper and started a manufacturing base to produce Velox paper, the first commercially successful photographic paper. In 1899, Baekeland and his business partners sold their company, Nepera, to George Eastman of the Eastman Kodak Co. for $750,000.

Now extremely wealthy, Baekeland set up a well-equipped research laboratory in the comfort of his own home. As part of the sale agreement with Kodak, Baekeland had agreed not to development any more photographic technology; he would need a new area of research.

As he had done with Velox, Baekeland looked for a problem that offered “the best chance for the quickest possible results.” Asked why he entered the field of synthetic resins, Baekeland answered that his intention was to make even more money.

By the 1900s, chemists had begun to recognise the potential of natural resins and fibres, but attempts to replicate these in laboratory settings had been unsuccessful.

Baekeland familiarised himself with previous work and performed his research in a systematic and well documented fashion, carefully controlling and varying the effects of temperature, pressure and the types and proportions of phenol and formaldehyde.


The production of polyoxybenzylmethylenglycolanhydride was the answer to Baekeland’s dreams. With the slightly catchier named of Bakelite®, the resin is combined with fillers, such as wood and asbestos before it’s pressed directly into the required final shape.

A multitude of different uses were found for this new material and Baekeland’s legacy can be seen across the Science Museum Group Collection. One of the most iconic is the Bakelite® phone

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
