普通U型玻璃（绿玻）ClearAppleton Uniprof™ Clear – profiled glass without any texture. As a design profiled glass without any ornamental structure on its outer face, Appleton Uniprof™ Clear is an alternative option to all translucent types of Appleton Uniprof™ glass. The transparency of this profiled glass permits its virtually undistorted and largely colour-neutral visual penetration. Optical deviations as compared with the visual penetration of flat glass are attributable to minor variations in surface flatness. These are due to the process applied and are typical of cast glass products.
