Plexiglass products mainly reflect the quality of the appearance through visual inspection points such as transparency, brightness and surface finish, but some strength requirements are often ignored by ordinary buyers or users. The surface hardness and toughness of plexiglass products are two important strength indicators. 

The hardness of plexiglass products is not high, but the toughness is good. The bending ability after heating is stronger than that of glass, but the surface is not hardened by tempered glass.
