Acrylic has high transparency, light transmission rate of 92%, and the reputation of "plastic crystal". And it has excellent weatherability, especially for outdoor use, ranking the top of other plastics. It also has good surface hardness and luster, great processing plasticity, and can be made into various shapes and products. Another variety of plates is rich in color (including translucent swatches). Another feature is that the plates can still maintain high transparency.
Acrylic production is difficult and costly, so there are many cheap and cheap substitutes on the market. These substitutes are also called "acrylic" and are actually ordinary organic boards or composite boards (also called sandwich boards). Ordinary organic board is made of common plexiglass pyrolysis material plus pigment. The surface hardness is low, and it is easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a thin layer of acrylic on the surface, and ABS plastic in the middle. It is easily delaminated due to thermal expansion and contraction during use. True and false acrylics can be identified from the slight color difference and polishing effect of the plate section.
In fact, acrylic is a kind of plastic, acrylic chemical name is pmma. Acrylic is the English name for acrylic in English, and it is actually plexiglass when translated.

In general, acrylic is relatively transparent, and transparency in plastic is relatively small, so there is no way to distinguish it. Acrylic buttons are one type of plastic buttons.
Acrylic is an improved version of plexiglass, which has higher abrasion resistance, plasticity, and light transmission. It belongs to a plastic. There is a line on the edge of the plastic that is left when the molds are closed together. There is also an edge on the edge or on the bottom.
