Bakelite

1907

Chemicals

Baekeland reacted phenol and formaldehyde into a resin that would not melt once it had set. Bakelite is the first truly synthetic plastic: not a modified natural gum, but a new solid. Radios, telephones, and distributor caps wore it. Plastics after it — polyethylene, nylon, PVC — inherited the idea that molecules can be designed for a job.

How it works

  1. React phenol with formaldehyde to a soluble resin.
  2. Heat and press so the resin cross-links into a thermoset.
  3. Mold it once; it keeps the shape even if reheated.
