Product Description: This PVC+ASA & PMMA synthetic resin tile extrusion machine adopts the advanced foreign technology, and designed for corrosion resistance of plant and heavy acid rain area, itâ??s a new generation of permanent roofing materials. This line adopts a processing two layer co-extrusion technology, each layer has different functions. Surface materials: weather ability resin to keep the durability and resistance to chemical corrosion of products. Underlying material: white ductile materials, to enhance the sense of space and brightness of house. The two different materials give the each features of product: smooth face and getting together well. The new PVC anticorrosive composite wave tile solves the problems of durability, corrosion resistance, small rigid, the sense of space and aesthetic.
