    摘要： Thermoplastic composition, comprising at least components (i) to (iii): (i) from 10 to 50 % by weight of a combination of at least one first ethylene polymer (A) and at least one second ethylene polymer (B), wherein (A) is selected such as to exhibit (±) a density of from 0.87 g/cm 3 - 0.90 g/cm 3 as determined according to ASTM D792; (²) a melt flow index of from 0.3 g/10 min - 5 g/10 min as determined according to ASTM D1238 (190 °C/2.16 kg); (³) a flexural modulus of from 5 to 60 MPa measured according to ASTM D790; and wherein (B) is selected such as to exhibit (±) a density of from 0.90 g/cm 3 - 0.92 g/cm 3 as determined according to ASTM D792; (²) a melt flow index of from 0.3 g/10 min - 10 g/10 min as determined according to ASTM D1238 (190 °C/2.16 kg); (³) a flexural modulus which is higher than that of (A); (ii) from 35 - 90 % by weight of inorganic particles as filler; (iii) from 0.05 - 20 % by weight of a liquid (at 23 °C) as a plasticizer for the at least one first ethylene polymer (A) and/or the at least one second ethylene polymer (B); the % by weight of components (i) to (iii) being based on the total weight of the composition.
