Abstract:
A composition comprising,(a) at least 30% and not greater than 70% by volume, based on the volume of the composition, of a melt processable polymer matrix component consisting of at least one of (i) a thermoplastic polyolefin elastomer of room temperature density less than 0.9 g/cc and (ii) a thermoplastic olefin/(ester or acid) copolymer elastomer, and(b) dispersed in said matrix, at least 30% by volume, based on the volume of the composition, of inorganic micro-balls of room-temperature density less than 0.6 g/cc, at least 80% by weight of the micro-balls having a maximum dimension less than 300 .mu.m.
