Catalin is a brand name for a thermosetting polymer developed and trademarked in 1927 by the American Catalin Corporation of New York City, when the patent on

expired that year. A phenol formaldehyde resin, it can be worked with files, grinders, and cutters, and polished to a fine sheen. Catalin is produced by a two-stage process, different than other types of phenolic resins, and does not contain fillers, such as sawdust or carbon black. Catalin is transparent, near colorless, rather than opaque. Unlike other phenolics, it can be produced in bright colors or even marbled. This fact has made Catalin more popular than other types of Bakelite for consumer products. Catalin is heavy, quite greasy in feel, and as hard as brass. It is heat resistant and does not soften under boiling water. Like Bakelite, it gives off a distinctive phenolic odour when heated and can be tested using Simichrome, which turns from pink to yellow.

Applications

Catalin was used from the 1930s to 1950s for many household objects, jewelry, small boxes, lamps, cutlery handles, and desk sets. Catalin jewelry, more commonly referred to incorrectly as Bakelite jewelry, was made from the 1930s until the end of World War II when it became too expensive, as every piece had to be individually cast and polished. The American Catalin Corporation introduced 15 new colors in 1927 and developed techniques to create marbling. The colors included yellow, orange, red, greens, blue, and purple, with clear, opaque and marbled versions. In the 1930s, jewelry made in these colors was popular with sets of beads, bangles, earrings, and rings being worn together. Emerson Model 400-3 Patriot (1940)
