UV, which stands for Stone Plastic (or Polymer) Composite.features a core that is typically comprised of around 60% calciumcarbonate, polyvinyl chloride and plasticizers.Because the core layer of SPC is composed of limestone, it is denser compared to WPC, though thinner overall Its high densityprovides better resistance to scratches or dents caused by heavyobjects or furniture placed on it, and makes it less likely to expandunder extreme temperat ure changes At the same time, it is extruded by T-shaped mold, which also avoidsthe intemal layer coating and gluing, so its functions are moreabundant, and it is non-toxic,formaldehyde free and zero pollution,with a series of characteristics such as renewable materials.so it canbe well used in interior decoration.
