Catalin is a phenol formaldehyde resin, and can be worked with files, grinders and cutters and polished to a fine sheen. Catalin is produced by a different manufacturing process, a two-stage process, than other types of phenolic resins. It 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.atalin jewelry, more commonly referred to incorrectly as Bakelite jewelry, was made from the 1930s until the end of WWII when it became too expensive, as every piece had to be individually cast and polished. The Catalin Corporation introduced 15 new colors in 1927 and developed techniques to create marbling.
