ABSTRACT:
A porous material of polytetrafluoroethylene consisting essentially of fibers of polytetrafluoroethylene. The porous material of PTFE is produced by heat-treating a molded article prepared by paste extruding of PTFE fine powder under such a condition that the heat-treated molded article shows at least one endothermic peak which appears between an endothermic peak position of the fine powder and an endothermic peak position of a sintered product thereof on a differential scanning calorimeter chart and then is stretched along at least one direction.
