Abstract
A polymer composition that contains an aromatic polymer in combination with a tribological formulation is provided. The polymer composition may exhibit a low degree of surface friction that minimizes the extent to which a skin layer is peeled off during use of a part containing the composition (e.g., in a camera module). For example, the polymer composition may exhibit a dynamic coefficient of friction of about 1.0 or less and/or a wear depth may be about 500 micrometers or less as determined in accordance with VDA 230-206:2007.
Claims11
A camera module comprising a base on which is mounted a carrier assembly, wherein the base, carrier assembly, or both comprise a molded part, wherein the molded part contains a polymer composition that comprises at least one thermotropic liquid crystalline polymer and a tribological formulation, wherein the tribological formulation includes a siloxane polymer having a weight average molecular weight of about 100,000 grams per mole or more and wherein the composition exhibits a dynamic coefficient of friction of about 1.0 or less as determined in accordance with VDA 230-206:2007.
