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 so-called hardness refers to the hardness of the object. Natural materials have high hardness and can be used to cut hard glass.
Toughness is the ability of an object to return to its original state after deformation. Although diamonds are hard but have low toughness, they are easily broken.
