KRATON\u00ae D1184 ASM is an asymmetric (branched) styrene-butadiene block copolymer (SBS) produced by Kraton Corporation. Grade designation: D \u2014 diene (butadiene)-based SBS series, 1184 \u2014 internal formulation index, ASM \u2014 Asymmetric (a branched molecular architecture with radial, star-shaped chains, as opposed to the linear D series).<\/p>\n
The styrene content of 30 wt % is a medium concentration that provides a balance of strength and elasticity. The branched architecture gives D1184 ASM three critically important properties that set it apart from linear SBS: 1)<\/strong> low melt viscosity at standard processing temperatures \u2014 easier hot-melt processing and adhesive application; 2)<\/strong> high cohesive strength \u2014 the adhesive does not flow under load; 3)<\/strong> retention of elasticity over a wide temperature range.<\/p>\n Supplied as a powder<\/strong> dusted with amorphous silica (anti-block agent) to prevent caking during storage and transport. This is a distinctive feature of D1184 ASM compared with pelletized SBS grades, which are more convenient for pellet feeding of extruders but less effective for direct hot-melt compounding.<\/p>\n Typical parameters: polystyrene content 30 wt %, MFR ~5\u201310 g\/10 min (200 \u00b0C \/ 5 kg), Mooney viscosity ML(1+4) 100 \u00b0C \u2248 50, Shore A hardness ~65\u201375, tensile strength 25\u201330 MPa, elongation at break 700\u2013900 %, compression set 30\u201340 % at 70 \u00b0C \/ 22 h. Density 0.94 g\/cm\u00b3.<\/p>\n Global market counterparts: ENI Versalis Europrene\u00ae Sol T 161 (linear SBS 30 %), Total Cray Valley Calprene\u00ae C 540 (radial SBS), Asahi Kasei Tufprene\u00ae A (linear SBS), LCY Globalprene\u00ae 3540 (radial SBS).
