Product Structure(Brand New):

The front cvoer is ETFE, which is imported from Japan. This materials can absorb more sunlight for its superior thinness. 

This materials can be integrated with the back sheet very well, and it will not easily to be cracked, expecially having excellent lifetime.

ETFE has a memory effect or selfhealing capacity in the event the panel comes into contact with branches etc, thus ensuring any slight abrasions are "healed" within a few hours.

ETFE has Non-viscous, dirt-resistance and good self-cleaning properties.
