Sterically hindered phenol technology has been and continues to be the premier antioxidant for plastic applications non-discoloring and highly effective. Emeralds legacy to our predecessor company B.F. Goodrich makes us a pioneer in the development and manufacture of this technology. Good-rite 3114 was invented and patented by B.F.Goodrich (predecessor company to Emerald) in 1972 (#3, 644, 277). Our plant in Henry, IL has been the sole production site for this material since the 1970s.
