Which Kind of Plastic Mirrors Can Replace Glass Mirrors Without deformation in the case of large areas? Firstly we need to understand the basic characteristics of these materials: 1.Acrylic mirror (Acrylic, Plexiglass, PMMA, Polymethyl Methacrylate) Advantage: high transparency, mirror coating can be on the opposite side, good protection effect of reflective coating, impact resistant (17xstronger than glass mirrors) and shatterproof, light weight, sturdy and flexible Disadvantage: a little brittle 2.PVC plastic mirror Advantage: cheap; high hardness; can be cut and bent into shape Disadvantage: the base material is not transparent, mirror coating can only be in the front, and low finish 3.Polystyrene mirror (PS mirror) It has low cost price. Its base material is relatively transparent, and it is relatively brittle with less toughness
