Has anyone seen MDF like this?

[pgrbff]

I bought a sheet of black coloured MDF yesterday, for an MFT table and a desktop for my son. This is the only product I can find locally and the pallet was labelled so I felt sure I could get a Spec. sheet and maybe even finishing details. Turns out the label doesn't belong to the product and the supplier is being difficult and won't give me a name.
It has two different faces looking from the side, one, the thin lighter stripe, appears to be a lamination of very thin layers. In reality, it is probably more dense and reflects more light so it only appears lighter in the image. The faces otherwise look identical.
I would mainly like to know the difference between the two faces but I have never seen anything like this.

All the MDF that i have used in the past is the same material throughout the board and not laminated as yours appears to be.

I’ve just had a look online and I’m surprised to find black MDf but it’s black all over , yours seems like regular MDf on the faces but black in between. Bit strange but it could be imported from overseas.

I suspect it has a higher density layer for better paint finish or for gluing or maybe as a balance for veneering the opposing side ?.
Could be a custom spec for a particular job.
I find the Medite stuff has a fluffier core and more dense edges but its not as pronounced as that. The black stuff is usually valcromat which is painfully expensive.

Have you cut into the sheet or routed the edge? Could it be the scoring saw rebate giving it a lighter colour?

Yes it has been cut, it was a 3m board, but it has nothing to do with machining, it is the whole board.

@petermillard may have some ideas after his recent jaunt to the Finsa factory - which seems to make some interesting MDF products?

Nope, never seen anything like that. If it was a ~3-metre board and definitely black, not very dark grey, then it’s not likely to be from Finsa as I’m told they only supply black Fibracolour in 2440x1220.

Is it valchromat?

I don't know. So far they have insisted they don't know who the manufacturer is. They are playing silly bu???rs.
