As a material permanently attached to the surface of a building, whether it is easy to break or fold does not fundamentally affect its normal use.
For example, the lenses of the glasses we wear are fragile, but it does not hinder their use. Normally, no one will drop the lenses on the ground. Similarly, MCM sheets are flexible and can be bent and made into special-shaped structures, but they cannot be folded repeatedly.
As a wall and floor finishing material, MCM sheets are not damaged by bending force after being placed on the wall or on the ground. As long as the surface has sufficient impact resistance, it is fine. Whether it is easy to fold or not does not affect its use function at all.
