PVC is one of the most used plastics in the building industry. PVC wallcoverings are widely used as suitable coverings for walls and roofs of buildings due to the unique properties and characteristics of PVC. The calcium-zinc stabilizers from Pishro Chemical Co., used in the production of these products, contribute to properties such as high flexibility, low density compared to similar products, non-flammability in case of fire, resistance to moisture, high strength, and impact resistance.
