Hi, Narenra. In my experience the best resource for plating on plastic, although it's very hard to find, is "Standards & Guidelines for Electroplated Plastics". It may explain why you are having etching difficulties.

Few plating shops know how to manufacture PPSU. Maybe an experienced plating shop or process supplier should develop the plating procedure? Good luck.
