Many plastics manufacturers made cast phenolics catalin using their own names for the plastic.
For using the patented process, they each had a licensing agreement with the Catalin Corp.
Opalon was another cast phenolic catalin plastic,
the name given by its maker, Monsanto Plastics.
Both Monsanto Corp (Opalon)⤴ and Marblette ⤵ contributed to Emerson's catalin radio models.
This Bakelite Corporation ad shows cellulose acetate and cast phenolic catalin plastic uses,
including the rare Fada model L56 radio.
They are grouped together, referred to as "Bakelite Plastics". The Catalin Corporation also made other plastics such as Styrenes and Polyethylenes.
Although labeled "Catalin Styrene and Polyethylene",
these are NOT the cast phenolics that are now known as catalin plastic.
Catalin in Europe
Dr. Fritz Pollak and Dr Alfons Ostersetzer, chemists in Vienna have been credited with catalin's creation in the mid '20s.

"1937 To exploit the market in Europe and the Commonwealth, Catalin Ltd was set up in England,
not as a subsidiary of the American concern but autonomous - although using the latter's technology.
Dr Riesenfeld, who had acted as consultant in America and was one of the inventors of the process, became technical director.
(There were at this time two other companies producing cast phenolics:
Marblette in the USA and Raschig in Germany, with processes differing in some respects from that of Catalin.)
The British company was installed in the large building in Waltham Abbey, Essex,
that had housed the Nobel company in the First World War which made munitions.
The building provided ample space to accommodate a battery
of six nickel reaction vessels (called 'kettles' in the American style) and six large circulating hot-air ovens
for curing (i.e. hardening) the cast resins in their moulds, together with ancillary pumps,
boiler, workshops, laboratories and offices."
