Due to the difficulty of acrylic production, high cost, so there are many quality low-cost substitutes on the market.

Ordinary organic board with ordinary organic glass cracking material and pigment casting, surface hardness is low, easy to fade, polishing effect is poor after polishing with fine sand. The composite board has only a thin layer of acrylic on the surface, and the ABS plastic in the middle is easy to delaminate under the influence of thermal expansion and cold contraction in use. True or false acrylic can be identified from the subtle color difference of the plate section and the polishing effect.
