The co-extrusion wall panel remian the advantages of traditional one like mildew and insect resistant ,abrasion resistant ,scratch resistant ,stain resistant and weather proof ,some properties are even better . The experimental data proves that the wear resistance and scratch resistanceare more than five times higher than the traditional one.

In addition ,the solid outter layer of the co-extrusion wall panel is effectively again the penetration of the colored liquids and oil-containing liquid,making the surface of the board very easy to clean. This outer layer can improve the resistance of the composite wall panel to sunlight , rain,snow,acid rain and seawater , so that the co-extrusion wall panel has an extremely long service life .
