<p>The upper layer of the sheet to be used as a worktop in a kitchen or a laboratory is made of porcelain-ceramics, which is resistant to scratching, acids and solvents, fire, heat and frost, mould and fungi. At least three aluminum layers with polyurethane layers of an extremely high density between them are used as a base for the porcelain-ceramics cover, resulting in an extraordinary stable quality of the sheet.</p> |
