Artificial pulp particles useful for producing paper-like sheet having excellent insulating property, heat resistance and reduced moisture-absorbing property, are composed of a plurality of fine particulate core consistuents consisting of a polyester material, for example, polyethylene terephthalate or polyethylene 2,6-napthalate, which are embedded whithin and connected to each other by a matrix constituent consisting of a heat-resistant aromatic polymer material, for example, poly-m-phenylene isophthalamide, which is soluble in a solvent not capable of dissolving therein the polyester material.
人工纤维素颗粒用于生产具有优异绝缘性能、耐热性和减少吸湿性能的类纸张片,由多种细颗粒核心成分组成,包括聚酯材料,例如聚对苯二甲酸乙二酯或聚对苯二甲酸2,6-萘酯,这些核心成分被嵌入并通过热稳定芳香聚合物材料组成的基体成分连接在一起,例如可溶于溶剂但不能溶解聚酯材料的聚间苯二甲酰胺。
