Carbon crystal board, actually known as "bamboo charcoal fiberboard," uses a substrate made from bamboo powder and PVC mixed with density board, with a PVC film laminated on the surface. It features low cost and quick installation, making it commonly used in commercial projects (such as mall partitions and budget hotels). For residential interiors, it is only recommended for limited use in dry areas. Suitable for non-load-bearing partitions or temporary spaces.
