(57) Abstract: A heat-meltable fluororesin and a fluororubber elastomer are contained, and the fluororubber elastomer is 100% by weight in total of the heat-meltable fluororesin and the fluororubber elastomer. And a fluororesin-based composition present in an amount of 1 to 60% by weight, formed bodies such as fluororesin-based films, sheets and tubes. A rubber layer and a fluororesin-based surface layer are laminated on the outer peripheral surface of the core material in this order in a concentric cross-section, and the fluororesin-based surface layer is formed by the fluororesin-based tube. . [Effect] This fluororesin tube has excellent friction characteristics while retaining the original characteristics of fluororesin such as non-adhesiveness, heat resistance, and abrasion resistance, especially non-adhesiveness. |
