Transparency is that light to affect the surface area when polymer morphology There are different Crystalline surface area, an arrangement that is more, not much space. So light don't residual effects,so don't transparency.Amorphous surface area, don't arrangement , and much space. So light residual effects,so transparency.
Opacity is light to affect the surface area when polymer morphology.There are different Crystalline surface area, an arrangement that is more, not much space. So, it's light, it's rarely fall impact caused a solid light. Best arrangement of the Amorphous with clutter, light effects. fell, not to solid light.
Gloss is to correlate the light reflection and refraction. When polymer morphology there are surface area different Crystalline arrangement that is more, not much space. So, it's light, it's rarely fall impact causes the opacity of light because there is no space for reflection, so it does not happen with Amorphous metallic parts arrangement that is not organized so that the light falls, the impact is greater transparency of its light, shining.
