What is this type of Foam?

I have gotten many items from Asian Suppliers via Amazon and so on.

Most have some Awesome packing. such as what in these 2 pictures.

It is foam, a very Dense Foam, I can Squeeze it, but it doesn't give much.

Can anyone tell me what potentially the Material or Manufacture name of the Product.

Hoping to get some to do a custom cutout case.

Thanks
