If Strictly speaking, the cork is in fact not wood, but oak bark. The main component of cork cork fiber per cubic centimeter, about 40 million cells in between the cells and the cell interior is filled with air. When subjected to external pressure, cells and their gap will shrink, while the loss of outside pressure, the air pressure inside the cell and between cells will make restitution.

According to reports, the full import of softwood general illumination time, the temperature of the Mediterranean region is appropriate, therefore better porosity its cork raw materials, the color lighter. The cork is generally made based on the Qinling Mountains, mostly wild, without good labor management, color darker. In addition, the technology, the wear resistance and elasticity contrast processing, domestic and imported cork cork also have some differences.
