摘要:
To provide a laminate which is formed from resins and is excellent in heat resistance and excellent in flexibility and mechanical properties under high-temperature conditions and which undergoes no separation of layers even when contacted with oil such as engine oil for a long period of time. The laminate comprises a first layer containing a fluorinated copolymer and a second layer containing a polyamide directly laminated on the first layer, wherein the fluorinated copolymer has units based on tetrafluoroethylene, units based on ethylene, units based on a copolymerizable another monomer not having a carbonyl group, and carbonyl group-containing groups, wherein the amounts of the respective units are in specific ranges, and the tensile elongation at 200° C. of the fluorinated copolymer is at least 200%, and the melting point of the polyamide and the flexural elastic modulus at 23° C. of the second layer are in specific ranges.
