    • A porous polytetrafluoroethylene (PTFE) material which is improved in bondability and is free from the problem of the buckling resistance on bending and tearing in the axial direction of tubes. This material is composed of a fibril part mainly comprising PTFE and a node part comprising a heat-meltable resin with a melting point lower than that of PTFE. The fibril part scarcely comprises the meltable resin. The production process comprises subjecting powdery paste extrusion material comprising particles of tetrafluoroethylene emulsion polymer and the above meltable resin to paste extrusion molding, optionally followed by rolling, to give an unsintered material, stretching the same at a temperature lower than the melting point of the meltable resin, and heat setting the stretched material at a temperature above the melting point of PTFE.
    • 一种多孔聚四氟乙烯(PTFE)材料,其粘合性提高,并且不存在弯曲和在轴向轴向撕裂的问题。 该材料由主要包含PTFE的原纤维部分和包含熔点低于PTFE的热熔性树脂的节点部分组成。 原纤维部分几乎不含可熔树脂。 制造方法包括将包含四氟乙烯乳液聚合物颗粒和上述可熔融树脂的粉末状糊料挤压材料进行糊化挤压成型,任选地随后进行轧制,得到未烧结材料,在低于可熔融的 树脂,并将拉伸材料在高于PTFE熔点的温度下进行定型。
