Abstract
Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support, an adhesive layer and a sliding layer. The adhesive layer is applied directly to the metal support. The adhesive layer comprises a blend of at least two fluoropolymers P1 and P2, wherein P1 is selected from perfluoroalkoxyethylene (PFA) or tetrafluoroethylene-hexafluoropropylene (FEP). P2 is different from P1 and can be a fluoropolymer.
