- Ring and Ball Softening Point: 115°C
- Glass Transition Temperature (Tg): 2.5ºC ± 7.5ºC
- Hydroxyl Number: 57 mg KOH/g
- Form: Solid
- Color: 4 max. (ASTM D 1544)
Comments: The properties mentioned are typical values and may vary slightly between different lots. Eastman does not guarantee that the material in any specific shipment will conform exactly to the given values.
Compatibility and Solubility: Eastman AQ™ polymers are compatible with some commonly used tackifiers and plasticizers in adhesive compounding. Tackifying resins compatible with AQ polymer include Staybelite™ Resin-E, Foral™ AX-E, Picco™ 6100, and Kristalex™ 3100. AQ Polymer is also compatible with benzoate plasticizers such as Benzoflex 9-88 and Benzoflex 352.
Packaging: The standard packaging for Eastman AQ™ 1950 Copolyester is a 40-pound box containing four blocks, each weighing 10 pounds. Each block is wrapped in a batch inclusion bag to facilitate easy handling.
Storage: Eastman AQ™ polymer must be stored in dry conditions to prevent absorption of water, which can alter its properties. Care must be taken not to rupture packaging materials to prevent leakage.
