               Main applications:

              Chewing gum SDG polyisobbutylenes are excellent chewing gum base ingredients.
              Medical adhesives SDG polyisobbutylenes offer excellent adhesion to the skin and cause no irritation or sensitization in skin contact applications. They are easy to peel off the skin.

               Packaging:

              Carton (20kg), Drum(45.4kg)
