UV layer and anti-fogging layer can be self-identified

Ultraviolet light is a key factor leading to the aging of the plate, so now more and more producers choose to co-extrude the UV layer (UV layer) sunlight board. The UV layer of the good quality sunshine board can not be measured only by the thickness, but also by the uniformity of its co-extrusion, to choose the UV layer thickness and good uniformity of the sunshine board.

The identification of the anti-drip sun board is actually very simple, that is, take a cup of hot water under the board, if the condensate water forms droplets or water droplets on the lower surface of the board, it indicates that the anti-drip effect is not good.
