Abstract

A composition comprising the following components: A) a first ethylene/alpha-olefin interpolymer with a melt index I2A; B) a second ethylene/alpha-olefin interpolymer with a melt index I2B; and wherein the difference in melt index (I2): (I2A−I2B)≥400, and wherein I2B≤100 g/10 min; C) a filler, and wherein the filler is present in an amount ≥50 wt %, based on the weight of the composition; D) a tackifier; and wherein the melt viscosity, at 165 C, of the composition, excluding the filler (component C), is ≤30,000 cP.
