Abstract
Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.
Claims20
A slide bearing comprising,
- a metal support;
- and
- a sliding layer extruded on and in direct contact with the metal support, wherein the sliding layer comprises one a fluorinated thermoplastic and one a non-fluorinated thermoplastic, wherein the fluorinated thermoplastic is comprises at least 60 wt % of the sliding layer, wherein the sliding layer comprises edges and a center region disposed between the edges, and wherein the fluorinated and non-fluorinated thermoplastics are disposed along the center region and edges wherein the fluorinated thermoplastic comprises a functionalized polymer.
A slide bearing comprising,
- a metal support;
- and
- a sliding layer extruded on and in direct contact with the metal support, wherein the sliding layer comprises a mixture of at least two polymers, wherein the mixture comprises one continuous phase, wherein the continuous phase comprises a fluorinated thermoplastic, and at least one discontinuous phase, and wherein at least a portion of both of the at least two polymers contact the metal support.
A method for forming a sliding layer containing polymeric droplets, the method comprising:
- blending at least two polymers P1 and P2 to form a blend, wherein P1 is at least 60 wt % of the blend;
- heating the blend to form a polymer emulsion;
- and
- extruding the polymer emulsion onto a metal support to form a sliding layer such that the metal support is contacted by both polymers P1 and P2.
