TR90 memory board frame is what?
In fact, there is no such frames, TR90 frame with the plate is different. 1, from the material comparison: TR90 frame is the use of nylon material (also known as nylon 12 or PA12), is the most popular ultra-light frame material, with light weight, good toughness, super safety and other characteristics, with super Flexibility, wear in motion will never break. (Except fake and shoddy products). Plate frame is the use of acetate fiber or propionic acid fiber. Injection molding or suppression of grinding production. 2, the process comparison: TR90 frame process complex, the injection of glass factory and spray paint process requirements are relatively high. Plate rack: Although the plate rack less painting, but in the work than the TR90 frame process to be much more, more complex process. 3, the use of comparison: TR90 Frame: light weight, comfortable to wear, more secure, more difficult to deformation. The only drawback is that it will fade. Plate frame: the same size of the frame relative to the TR90 frame will be more weight, the bridge of the nose will have the feeling of oppression, comfort is not as TR90 frame, flexibility and safety than the TR90 frame slightly worse. The advantages of three-dimensional sense of strong, three-dimensional edges and corners of the TR90 frame can not be compared, but also not out of color. )
