PMMA has the advantages of light weight, low price and easy molding. Its molding methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be mass produced with simple process and low cost. Therefore, it is widely used in instrument parts, automobile lamps, optical lenses, transparent pipes and so on. Due to the difficulty and high cost of acrylic production, there are many low-cost substitutes in the market. These substitutes, also known as "acrylic", are actually ordinary organic boards or composite boards (also known as sandwich boards). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. The surface hardness is low, easy to fade, and the polishing effect is poor after grinding with fine sand. The composite board only has a very thin layer of acrylic on the surface, and ABS plastic in the middle. It is easy to delamination due to thermal expansion and cold shrinkage in use. The true and false acrylic can be identified from the slight color difference and polishing effect of the plate section.
