I didn't know so many MM have already got experience until I post this article. I followed my guidline, that is practicle and good quality.
If you are talking about the material for the kast door, ours is rough plastic, the basic one, because that is hardest, and won't be dirty so easily. Hoogglans is chic but have to clean very often, and it's sensitive to scratch.
If you are talking werkblad, then indeed the mdf can't resist the heat.
