How about the quality of endurance board resolution
in fact sheet identification is not so difficult, and to identify the way is very diverse. Want to see the endurance plate is good, you first can see the transparent sheet, and in general light transmittance, the higher the better, because the material production of residual is more, pervious to light and poor quality of a material is also not very good. At the same time we also see the thickness of the sheet, the thicker the apparently materials used in the raw material is more, the quality of the natural is better. Because of this plate can be bent, you can also see the degree of bending problem, if the curvature is small, and it's easy to brittle fracture, so suggest that we do not choose this material use time will not very long. You can also take a look at the price problem, it is often said that a penny a points goods, this is also a lot of sense. If the price difference is too big, too much lower than the market price sheet, in particular, obviously not worth choosing endurance plate.
