Second generation - PVC material

PVC material, PU is difficult to penetrate to a height of 1.52 meters in the early stage of manufacturing, while PVO material can be easily achieved, and it is lightweight and easy to stretch. However, its disadvantages are equally obvious as PU, such as many scratches, discoloration, yellowing, oxidation, etc.
