What is this material please?

[kevkdg]

I was taking up a laminate floor, and most of the under boards were the standard type, but it looks like whoever laid it ran out of the green laminate under boards and used this for a small section.

Any ideas what it is.

Has the letters ACC or could be ACO printed on it.

Fibre underlay boards?

I've had the green underlay boads and some which were beige/brown colour similar to cheap hardboard.

If you are concerned about it, thoroughly dampen it before moving it.
This will prevent airborne particles.
