Its basically their version of Bakelite, since Bakelite was Copyrighted/Patent Protected. 


Of course Bakelite is completely different from the Micarta that Westinghouse had invented and used on their fan blades for many years which many people confuse for Bakelite (completely different manufacturing process).


The Reason why one would consider Hemcolite a form of Bakelite is because true plastic as we know it now wasn't invented until the 1960s.  :D

Hope this helps!

Bakelite can be any color you want, you usually color the bakelite during the mixing process, and or paint it. 


I've seen many Many Bakelite radios that were colors other than black, like white, Brown, Red, Blue, Green, etc. 

Most of the time, the cheapest way to color Bakelite was to paint it, the more expensive way to do it was to add color dyes to it during the mixing process.

Hemco was a urea based plastic, also marketed as , originally owned by the plastics division of Bryant Electric and bought by Westinghouse in 1941 for use in their own electrical applications, and in the manufacture of dishes, aircraft parts and a large amount of other objects including fan blades. It is very true that Bakelite is a form of plastic, but it has no bearing on this subject, which is blade materials used in the manufacture of Westinghouse fans.            Hemco Plastics Division of Bryant Electric Company

In 1946, it is stated that through "Plastics Business" the Bryant Electric Company, Westinghouse owns Hemco Plastics Company, a leading custom molder of plastics.

Ok, but the point I was trying to make is the plastics that was used in this application, bakelite, and other related plastics aren't considered to be modern plastics because they aren't made like modern plastics like ABS or PVC or other related modern Plastics. 
Plastcon (sp?) was the first true modern plastic which was developed by GE and RCA for use in their pocket transistor radios and table radios and TVs in the early 1960s. 

Thanks for the correction about the Hemcolite, but I was mainly trying to explain that it's not considered a modern plastic.
