The high-hardness impact-resistant composite board produced by our company takes optical grade PMMA/PC two-layer composite board as the base material and adopts unique nano-strengthening technology to make the surface hardness of the PMMA surface reach 6-8H, and its wear resistance is ordinary. More than ten times that of PMMA reinforced plate, the wear resistance reaches 0.2. Under such a high surface hardness, the impact resistance can reach 0.28mj/cm². Combined with the excellent processing characteristics, it can replace glass on the touch screen, which can not only reduce the weight of the final product but also improve its safety performance. The material properties of plastic make it more suitable for styling than glass, which opens up more space in the design of the final product.
