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 is directed to composite structures, such as low friction liners, exhibiting superior performance. In certain embodiments of the present disclosure, a composite structure can include a first outer major surface adapted to contact a movable surface, and a second outer major surface adapted to contact a stationary surface, wherein the first outer major surface has a lower surface roughness than the second outer major surface, and wherein the composite has a mean average thickness of less than 0.3 mm. The composite structure can have unexpected synergistic improvement in properties such as low surface roughness, high dielectric strength, high resistance to edge wicking, high resistance to surface wicking, low content of surface defects, an increased abrasion resistance, and combinations thereof, particularly the maintenance of these properties over a long life.
