Abstract
Compositions comprising (i) a hydrogenated styrenic block copolymer, (ii) an oil, and (iii) optional additives are described herein. Compositions include but are not limited to cable fillings. The styrenic block copolymer having peak molecular weight of from about 125 to about 300 kg/mol, an oil and optional additives are described herein. The block copolymer includes a B block having vinyl content of from about 35% to about 49% and an S block having a polystyrene content of from about 28% to about 40%. The compositions may form a gel having a thixotropic ratio at 25° C. of from about 5 to about 10 and further characterized by specific low, middle and high shear rate viscosities at 25° C. and shear rates of 6 s, 50 sand 200 sof from 10,000 cps to 750,000 cps, 1,000 cps to 100,000 cps and 1,000 cps to 6,000 cps, respectively; a drop point from 100° C. to 250° C.; and a cone penetration at 25° C. of from 300 dmm to 685 dmm.
