Specialized Technology Resources, abbreviated as STR,[1] was an American corporation headquartered in Enfield, Connecticut.
STR was founded in 1944 under the name DeBell & Richardson Inc.[4] as the first dedicated plastics research and development firm in the United States.
STR launched its quality assurance business in 1983 and commenced sales of its solar encapsulant products under the PhotoCap trademark in the late 1970s.
When the business was sold in 1991, and subsequently split and merged in 1996, the company changed its name to Springborn Testing and Research and branded the letters “STR.” In 1998, the company again changed its name to Specialized Technology Resources and still is referenced as “STR.” In June 2007, DLJ Merchant Banking Partners, a division of Credit Suisse, purchased STR.
On November 6, 2009, STR had its initial public offering on the New York Stock Exchange under the ticker symbol, STRI.
