Description
An early type of polymer. Thiourea formaldehyde resins were patented in 1923 by Frits Pollack of British Cyanides Co. and later introduced as molding powders in 1928 under the brand names of Beetle and Beatl. These lightweight plastics were made inpastel colors for inexpensive clock cases and radios. Beetle resins were not used for jewelry. These cellulose filled resins were soon superseded by Urea formaldehyde resins.
