Bakelite, invented by Leo Baekeland in 1907, was the world's first fully synthetic plastic. This thermosetting polymer is a phenol formaldehyde resin known for its heat resistance, durability, and electrical insulation properties, making it ideal for early electrical components, radios, telephones, and household items.

Key characteristics
Synthetic resin:
It was the first plastic to be completely man-made from synthetic components.
Thermosetting:
Unlike thermoplastics, Bakelite undergoes a chemical change when heated, permanently hardening and becoming infusible.
Durable and resistant:
Bakelite is known for its hardness, chemical resistance, and ability to withstand high heat.
Electrical insulator:
Its non-conductive properties made it crucial for electrical applications.
Asbestos content:
Early Bakelite often incorporated asbestos fibers as a filler to enhance its heat and electrical resistance, a dangerous component that is now banned.
Uses and cultural impact
Electrical goods:
It was widely used for electrical fittings, housings for radios and telephones, and other electronic components.
Household items:
Bakelite was a popular material for kitchenware, jewelry, cigarette cases, and various other everyday objects.
Collecting:
Vintage Bakelite items are now popular collector's items due to their historical significance and unique aesthetic.
Inventor
Leo Baekeland: The Belgian-born American chemist who patented the process for creating Bakelite in 1907 and was granted the patent in 1909.
