Hi, is this item pure white or does it have black speckles in it? Need to be pure white for reflectors in photography studio

Hi, there is no black in the surface, but it is not what I would call pure white. As with most polystyrene foam, the foam is formed from bubbles, which are cut to make the sheets. This gives a certain pattern to the surface finish. I cannot say what the reflective properties would be - we used it to block light coming into our church windows when we were showing a video presentation and it is very successful in that role.

Have successfully used the sheets as back drops and as large reflectors. The surfaces were a good white and fleck free.

Is this “closed cell” non absorbent? Or does it soak water up?

Hello Tony I have just soaked a couple of off cuts of this material for 2 hours in water then broke both pieces in half and applied a piece of toilet tissue to the two broken surfaces and both remained totally dry so I would say that it does not allow the ingress of liquid.
