ORIENTED POLYMER COMPOSITION WITH INORGANIC FILLER AND LOW XYLENE SOLUBLES

摘要

Tensile draw an orientable polymer composition wherein at least 50 weight-percent of the polymers in the orientable polymer composition are polypropylene-based polymers and wherein the orientable polymer composition contains four weight-percent or less of a combination of polypropylene xylene solubles and ethylene/propylene copolymer xylene solubles and ten volume percent or more of inorganic filler to prepare a cellular oriented polymer composition having a density of 0.85 grams per cubic centimeter or less and a flexural modulus of 4137 megaPascals (600,000 pounds per square inch) or more.
