The moisture problem潮湿的痛点
MDF and plywood swell. This board does not.密度板与胶合板会涨边，这种板不会。
A bathroom vanity built from standard MDF will fail at the cut edges and hinge screw holes within three to five years — even with edge banding. Foamed PVC is closed-cell and homogeneous, so water has nothing to soak into. Cut it, drill it, screw into it: the core stays waterproof throughout.用普通密度板做的浴室柜，即使封边，也会在三到五年内在切口与铰链螺钉孔处损坏。PVC 发泡板为闭孔均质结构，水无处渗透。开料、钻孔、拧螺钉，芯层始终保持防水性能。
- 100% waterproof through the whole thickness全厚度 100% 防水
- Termite-proof and rot-proof防白蚁、防腐烂
- Lightweight — 60% lighter than MDF of the same thickness轻质 — 同厚度比密度板轻约 60%
- Machines and edge-bands with standard woodworking kit可用常规木工设备开料与封边
