Introduction of protective film for aluminum panel

- Jul 11, 2019-

1. Aluminum composite panel protective film is a crystalline material, which is easy to crystallize. If it is not cooled rapidly, it will inevitably reduce the transparency and elongation at break. The blow molding process has poor cooling effect, high crystallinity, and low film transparency. 2, due to blowing up, drafting, serious molecular orientation, resulting in low elongation at break; and casting production has good cooling effect, low crystallinity, good transparency, low degree of orientation, so high elongation at break, retractability Good. 3, need to add the right amount of anti-fogging agent. 4. On the basis of the above, a transparent nucleating agent is added. 5, Aluminum composite panel protective film raw material selection on the choice of low haze, melting refers to
