Tough thermoplastic resin sheet-like material

摘要

According to the present invention, rolled sheet-like materials having superior mechanical properties, in particular toughness and high-impact properties, as well as superior heat resistance and showing no whitening can be provided. Such rolled sheet-like materials are manufactured by isotropically rolling sheet-like materials, which were obtained by melting, blending and forming the mixture consisting of thermoplastic resin having the degree of crystallinity of 10% or more of 20 to 90% by weight and flaky fillers of 10 to 80% by weight, to orientate a part of crystals after it was melted at the melting point of said sheet-like materials and then recrystallizing the melted crystals under the rolled condition.
