During the mid-sixties, the advent of synthetic fungicides moved Georgia Gulf Sulfur into broader industrial sulfur markets. The resulting present day mix of EPA registered pesticides and trademarked products for the rubber, heavy industry, and specialty manufacturing industries has allowed Georgia Gulf Sulfur to grow and prosper through the years. Georgia Gulf Sulfur separated from the parent corporation in 1982 and became a privately held company.

BAINBRIDGE CHEMICAL CORPORATION, a homogenized sulfur manufacturer, specializing in fluid and flowable sulfurs, began operations at the Georgia Gulf Sulfur Bainbridge site in late 1983

In July 1988, Georgia Gulf Sulfur purchased HOLLY INDUSTRIES in Acton Ontario Canada, to further compliment expanding product lines and reach more distant markets in the United States as well as Canada. The Holly process equipment was moved to Acton in 1978 from a former FMC Corporation plant site in Burlington Ontario.

In January 1993, Georgia Gulf Sulfur purchased the Rhone-Poulenc sulfur plant in Freeport Texas, (previously operated as Stauffer Chemical Company) and renamed the facility S.F. SULFUR CORPORATION. There has been a sulfur processing plant operating at the Freeport site since 1916.

In June 1997,Georgia Gulf Sulfur purchased controlling interest in INTERNATIONAL SULPHUR INC. of Mt. Pleasant Texas. Operating in Houston Texas since 1950, International Sulphur moved to Mt. Pleasant in 1969 to be near a sulfur source. A second plant in Middle Point Ohio was consolidated to the Mt. Pleasant location in 1986.
