• gt Isosorbide is a chemical intermediate for
  production of
• Dinitrate isosorbide for pharmaceutical
  applications (vasodilators)
• Dimethylisosorbide as an environment friendly
  solvent
• Isosorbide fatty esters as a non-ionic
  surfactant

gt Isosorbide is a comonomer for new  high Tg 
polymers

Isosorbide Value Creation for PET Containers
PET Hot Fill Containers

• Higher Tg performance creates new opportunities
  for PET beyond todays limitations

• Cost savings options include eliminating need
  for heat-set operation, provides faster cycle
  time and/or weight savings

• Performance demonstrated by Plastics Technologies
  Inc.

Isosorbide Value Creation for PET Containers
PET Beer Bottles

• Higher Tg performance allows pasteurization on
  existing lines

• Flexibility for bottle design including use of
  champagne base

• Flexibility for use with mono-layer or
  multi-layer barrier technology

Currently Evaluating Results at Independent Labs
