✦ Synopsis
Effects of different melting temperatures (270 and 210°C), Al flake widths (0.5 and 0.8 mm), and coupling agents (gamma aminopropyl triethoxy silane A1100 and gamma glycidoxy propyl trimethoxy silane A-187) on the properties of ABSϩ20%PC/Al flake-metallized plastics are discussed. According to experiments, it is found that the aspect ratio is larger with the 270°C melting temperature and 0.8 mm Al flake, but declines with the A-187 coupling agent. The 0.5 mm Al flakes treated with the A-1100 coupling agent at 270°C melting temperature has better distribution in the matrix and EMI shielding effectiveness, but has a lower volume resistance. With 0.8 mm Al flakes at 210°C melting temperature, and treatment with the A-1100 coupling agent, it produces larger ultimate tensile strength and impact strength. There is no relation between HDT and melting temperatures, Al flake widths, or coupling agents.
