In 1941, William Doyé Neuberg founds the William D. Neuberg Company, chemical brokerage firm in the Graybar Building in New York City. The company is incorporated in 1945.
The Shamrock Chemicals Corporation is formed in 1951 as a subsidiary of the William D. Neuberg Company, concentrating on the sale of powdered waxes.
William B. Neuberg, son of the founder, pioneers the introduction of micronized polytetrafluoroethylene (PTFE) powdered wax to the ink market, which changes the shape and mission of the company.
Three subsidiaries of the William D. Neuberg Co. are merged, forming a new entity under the name Shamrock Chemicals Corporation. William D. Neuberg assumes the role of chairman, and William B. Neuberg is named president of the new organization. Corporate headquarters and operations are consolidated in Newark, New Jersey. Meanwhile, new applications for PTFE are discovered for the coatings industry, triggering a significant growth in sales. This growth leads the company to extend its reach with sales agents in Asia, Australia and Europe.
The Newark facility is expanded to accommodate increasing demand, and Shamrock installs its first electron beam accelerator. The expansion brings the Newark facility to almost 100,000 square feet. Shamrock S.A. is founded in Switzerland and a new sales reps are established for South America. In 1988, the company is renamed Shamrock Technologies to reflect its changing focus and expertise.
Founder William D. Neuberg dies in 1992 at age 97. His passing leaves an inspiring legacy of business success and growth. With demand for its products increasing, Shamrock acquires a second manufacturing facility in Henderson, Kentucky. The company expands again, building an auxiliary plant in Henderson, bringing the company’s total manufacturing facilities to almost 300,000 square feet.
Shamrock celebrates the grand opening of its European Headquarters in Tongeren, Belgium, in 2001. This is followed by the opening of its Tianjin plant in China in 2004. A third plant is built in Kentucky in 2007. Shamrock expands its Newark facilities yet again to support additional new product development for a growing line of liquid dispersions, emulsions and unique submicron technologies. Shamrock’s worldwide manufacturing facilities now top more than a half million square feet in six facilities across three continents.
