Boonton Rubber Mfg. Co.; Boonton NJ: They at least made a "Radio Frequency Amplifying Unit" as a model 5 - for 200 to 600 meters wavelength. The logo is RFL, which reflects the creation of Radio Frequency Laboratories company out of the molding department at Boonton Rubber. There is also a book (35 pages): "Moulded Insulation Boonton Rubber Manufacturing Co., Boonton, New Jersey - Softcover (1914).

The Boonton Rubber Company started life as the Loando Hard Rubber Company. The company was located at 124 Fanny Road in Boonton, New Jersey.

Founded: 1891

In 1891, the Loanda Hard Rubber Company was founded by Edwin A. Scribner, and began the manufacture of molded hard rubber products. Seven years later, Mr. Scribner died, and the management of the firm fell to his son-in-law Richard W. Seabury. In 1906, it was Richard W. Seabury, who, casting about for new materials, learned of experiments with synthetic resins made by Dr. Leo Baekeland, for whom the well-known material, Bakelite, was later to be named. Richard W. Seabury, became the world's first molding of organic plastics in 1907.

The molding of vulcanized asbestos and the development of radio circuits may seen to be entirely disassociated activities, but it was in a tiny molding department of the Loando Hard Rubber Company that Boonton's world-renowned electronic industries first began. By 1950 these companies, Radio Frequency Laboratories, Boonton Radio Corp., Ballantine Laboratories, Measurements Corp., Aircraft radio Corp. and Ferris Instrument Corp. are known wherever precision instruments are used.

For many years (1906) Richard W. Seabury had been engaged in the development of molding processes for bakelite as a licensee under the patents of Dr. Leo H. Baekeland. Mr. Seabury's concern produced a great variety of molded parts including many pieces for electrical equipment.

In 1922, business was thriving and the future looked very bright as an enterprising new industry, radio broadcasting, was sweeping the nation. There were big demands for moldings of coil forms and many of the parts that were used in the early radio sets but it was soon discovered that material which was satisfactory for ordinary electrical use was a poor insulator at radio frequencies. To solve the problem and thus meet the requirements of his customers, Mr. Seabury engaged the help of a competent radio engineer, Dr. Lewis M. Hull, who years later was to become president of Aircraft Radio Corp.

Dr. Hull and his associates, while working on various molding materials, had to devise new electronic devices for test purposes. In doing so, their creative minds brought forth circuits that were innovations to the art and the radio industry deluged them with new technical problems to solve. Thus a tiny molding plant had spawned a highly technical new enterprise that in 1922 became known as the Radio Frequency Laboratories, known simply to radio men as RFL.
Other financial backers included Dr. Edward Weston, of instrument fame, Valentine B. Havens and Clinton P. Townsend, noted attorneys. Additional radio engineers were engaged, one of these being Stuart Ballantine who, until his death in 1944, was to make some of the most important contributions to radio that the first half century was to witness. Another capable engineer who joined this group was William D. Loughlin who held the office of president of RFL from 1930-1934 when he established his own company Boonton Radio Corp.
Boonton Molding Company (founded 1920):
This is not the same company but shows us who was the founder fo Boonton Rubber Manufacturing Company. Taken from "" where you find an interesting timeline with history for plastics:
"After working for five years for his brother-in-law at the Boonton Rubber Manufacturing Company (founded by his father), George Scribner (1891-1972) founded the small Boonton Molding Company down the street from the Boonton, New Jersey, family business. Starting with one press, the new company grew quickly to become a leader in the manufacture of phenolic plastic products, developing new molding techniques and applications. By the 1930s the Princeton- and Columbia-educated Scribner was also expert in the use of urea formaldehyde press molding, and was experimenting with injection molding. By the 1950s Boonton was producing the top-rated (by Consumer Reports) melamine Boontonware, which kept two of the three Boonton molding plants in operation producing hundreds of thousands of the stylish and near-unbreakable dishes."
