    Abstract: A thermoplastic composition includes a polymeric base resin, a glass fiber component, and a laser direct structuring additive. The laser direct structuring additive includes copper chromite black, copper hydroxide phosphate, tin-antimony cassiterite grey or a combination thereof. In some aspects the polymeric base resin includes polybutylene terephthalate (PBT), polyamide (PA), polycarbonate (PC), poly(p-phenylene oxide) (PPO), or combinations thereof. In certain aspects the thermoplastic composition has a nano molding technology (NMT) bonding strength of at least about 20 MPa when bonded to aluminum alloy. In further aspects the thermoplastic composition includes a plating index of at least a about 0.25. The disclosed thermoplastic compositions can be used to form articles such as NMT bonded covers of consumer electronics devices.
