ContactAdvantages:
For its outstanding anti-aging property, ASA film is widely used in roof tile field. In the process of roofing tile, it can achieve on-line thermal composite, with uniform thickness, no color difference and high bond strength. It overcomes the color difference of traditional co-extrusion ASA composite, and also deals with the cost of raw materials. The thickness of the ASA surface is 0.05-0.2mm, max width 1500mm, uniform thickness and stable dimension.
