Versalis Europrene® SOL T 9131 Styrene - Isoprene Block Copolymer  (discontinued **)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Styrenic TPE

Material Notes: Europrene® SOL T 9131 is a linear block copolymer obtained by anionic polymerization. The polymer is based on styrene and isoprene, where bound styrene content is 15% weight and diblock content is 40%. A non-staining, TNPP free antioxidant system is added during the production process.

Key Features: Europrene® SOL T 9131 is a block copolymer with linear molecular structure and high diblock content, designed for hot melt pressure sensitive applications where improved tackiness and softness, as well as reduced viscosity, are required.

Main Applications: Hot melt pressure-sensitive adhesive for labels or high tack tapes.

Information provided by Polimeri Europa. Mechanical properties measured on ASTM D 4703 compression molded samples.
