Material environmental protection: The mould proof Carbon crystal wall panel is made from environmentally friendly raw materials such as natural bamboo charcoal powder, calcium powder and food-grade PVC.The production process does not use formaldehyde containing adhesives, and the formaldehyde emission is ≤ 0.05mg/m ³, far superior to the national E0 level standard.The bamboo charcoal molecules inherently possess adsorption capabilities, which can degrade the free formaldehyde in the indoor environment.The paint free coating process further reduces pollution.The elderly, children, pregnant women and families can all use it with peace of mind.
