SEPTON™ HG252

Technical Datasheet | Supplied by Kuraray
SEPTON™ HG252 by Kuraray is a SEEPS-OH (hydroxyl group-containing styrene-ethylene-ethylene/propylene-styrene) grade. It is used as a polar resin modifier and a polar/non-polar resin compatibilizer. It is a non-toxic, recyclable product exhibiting rubber-like properties over a broad temperature range owing to high heat resistance. It offers excellent mechanical properties, weather- & chemical resistance (acid, alkali, alcohol) and good low-temperature performance. It shows outstanding strength, electrical insulation and rubber-like elasticity. It is soluble in petroleum benzene, toluene, hexane, chloroform, cyclohexane, tetrahydrofuran and partially soluble in ethyl acetate & methyl ethyl ketone. It is insoluble in methanol, ethanol, acetone, water and dimethylformamide. SEPTON™ HG252 by Kuraray can be used in plastic modifiers, toys, sporting goods, soft-touch grips, non-woven fabric and automotive parts applications.
