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.
