processability and is typically determined at 375 °F (190 °C), as per the ASTM D-3236 or DIN 53019 test methods. Needle penetration (NP) - indicates resistance to deformation and hardness, and is typically determined as per ASTM D-1321, ASTM D5 or DIN EN 1426 test methods Ring and ball softening point (RBSP) - indicates resistance to heat, and is typically determined as per ASTM E-28 or DIN EN 1427 test methods. Open time (OT) - indicates how long it takes for a film of adhesive to set to a destructive bond. Typically determined as per ASTM D-4497. Other tests carried out to determine product properties are: Rheology- measured with a rheometer Tensile strength and modulus - measures mechanical properties - measured using a tensile tester Molecular weight - used to obtain the molecular weight distribution, MWD, determined by Gel Permeation Chromatography, GPC Shear adhesion failure temperature (SAFT) Peel adhesion failure temperature (PAFT) Applications Applications include: Personal hygiene baby diapers Adult incontinence Feminine hygiene Paper and packaging Paper lamination Cardboard and case sealing Pressure sensitive labels Bookbinding WoodworkingEdge banding References Pellon, B.J. and A.
