Abstract: The present disclosure relates to a low friction bearing liner for a solenoid that may include a core layer, a first outer layer overlying a first surface of the core layer, a second outer layer overlying the first outer layer, a first inner layer overlying a second surface of the core layer that is opposite of the first surface of the core layer, and a second inner layer overlying the first inner layer. The first outer layer and the first inner layer may include a fluoropolymer material and may have a melt flow rate of at least about 2 g/10 min at 372° C. The second outer layer and the second inner layer may include a fluoropolymer material distinct from the fluoropolymer material of the first outer layer and may have a surface coefficient of friction of not greater than about 0.2.

Abstract: The present disclosure relates to a composite article that may include a structural substrate, a multilayer fluoropolymer film that can include a high-melt fluoropolymer layer and a low-melt fluoropolymer adhesion layer that may contact the structural substrate and the fluoropolymer film. The high-melt fluoropolymer layer may have a melting temperature A1 and the low-melt fluoropolymer adhesive layer may have a melting temperature A2. The melting temperature A2 may be less than the melting temperature A1.

Abstract: The present disclosure relates to a low friction bearing liner for a solenoid may include a low friction layer. The low friction layer may include a first fluoropolymer matrix component and a first thermoplastic filler component distributed throughout the first fluoropolymer matrix component. The content of the first fluoropolymer matrix component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer. The content of the first thermoplastic filler component may be at least about 1 wt. % and not greater than about 99 wt. % for a total weight of the first low friction layer.
