Types of core materials for aluminum composite panel

There are two main types of core materials for aluminum composite panel: breakable and unbreakable.
When a breakable aluminum composite panel is bent to a certain angle, cracks will appear in the middle of the board, causing it to break from the middle; When an unbreakable aluminum composite panel is bent to a certain angle, the middle of the board can still maintain its shape and will not break. Breakable aluminum composite panel is usually used in flat buildings, such as rectangular walls. unbreakable aluminum composite panel is mainly used in cylindrical or irregular buildings, such as circular columns.
