PU Artificial Mountain Stone is a new type of lightweight flame-retardant artificial landscape decoration material made of polyurethane (PU) as the core material. It highly restores the rugged contour and natural three-dimensional undulating layers of natural mountain rocks, combining wild natural rock aesthetics with the practical advantages of modern PU craftsmanship. It is widely used in scenarios such as indoor landscape rockeries, commercial scene decoration, villa outdoor gardens, scenic layouts and interior feature walls, which can not only create an immersive wild natural mountain atmosphere, but also avoid the pain points of natural mountain stone such as overweight texture, poor fire resistance, fragility and difficult manual shaping, endowing architectural and gardening spaces with a natural and grand high-end visual experience.
