摘要:
To provide a resin-coated metal pipe which is excellent in corrosion resistance and impact resistance, wherein adhesion between a plating layer and a resin coating layer is good even without a primer layer, and whereby the number of steps at the time of production is small, and the environmental burden is low. A resin-coated metal pipe (10) comprises a metal pipe (12), a plating layer (14) formed by hot dipping plating on the outer peripheral surface of the metal pipe (12), and a resin coating layer (16) formed by melt molding on the surface of the plating layer (14), wherein the resin coating layer (16) is made of a resin material comprising a melt-moldable fluororesin (A) having at least one type of reactive functional group selected from the group consisting of a carbonyl group-containing group, a hydroxy group, an epoxy group and an isocyanate group.

An objective of the present invention is to provide a sliding member for sheet-shaped recording material detachment having superior resistance to abrasion and superior heat resistant rigidity , and either a seal ring for an automobile or a seal ring or a sliding member for an industrial gas compressor, having high mechanical strength while ensuring flexibility. The objective is achieved with a sliding member for sheet-shaped recording material detachment, and either a seal ring for an automobile or a seal ring or a sliding member for an industrial gas compressor, made from a resin composite comprising: as a first element, either an adhesive fluorocarbon resin (A) or a resin compound of the resin (A) and a fluorocarbon resin (B) which differs from the resin (A), which are in a volumetric ratio (A/B) of 5/95 to 99/1; and as a second element, 0.5 to 99volume% of a thermoplastic polyimide (C).
