Summary

[edit]
Description

Bakelite, developed in 1907, was wholly synthetic and, once molded, retained its shape permanently. Its synthesis represented a turning point, opening up new ideas about how plastics could be used in consumer goods and industry. Dubbed “Old Faithful” by its early operators, the steam pressure vessel was used to produce commercial quantities of Bakelite beginning about 1909. In the Bakelizer, a mixture of phenol and formaldehyde was hardened at a temperature of 150° C and a pressure of about 100 pounds per square inch—enough to suppress the foaming from the reaction that would otherwise produce a weak and porous product. In time Old Faithful was joined on the plant floor by other Bakelizers.

In 1993, the American Chemical Society declared the original Bakelizer its first National Historic Chemical Landmark.
