1.What is PU Stone? A High-Performance Stone-Imitating Decorative Material
PU Stone = The Aesthetics of Natural Stone + The Performance of Industrial Products.
It does not absorb water or effloresce, does not weather or crack, does not require wet pasting or dry hanging, and can be installed by ordinary carpenters. It is a modern alternative to natural stone.
PU Stone (Polyurethane Stone-Imitating Decorative Panel) uses polyurethane polymer material as the base material, which is foamed and formed through precision molds to truly replicate every texture of natural stone. However, its weight is only one-fourth that of natural stone, and it has excellent waterproof and weather-resistant performance, with extremely convenient construction.
Haining Longtime Industry Co., Ltd. has a full range of PU stone products from classic mushroom stone to modern geometric styles, meeting various indoor and outdoor decorative needs.
