Polycarbonate is an amorphous material, and as such, has somewhat compromised chemical resistance. I would expect no problem with PC in contact with steel or aluminum, but you may have difficulty with the melamine and/or the vinyl. The reason for this is the other chemicals in these two plastics. For example, the vinyl will contain plasticizers that will likely leach out over time and come into contact with the PC. In the case of melamine, it is likely to contain at least some solvent and/or unreacted monomer that will come into contact with the PC. It is very difficult to judge whether the chemicals leaching out of the vinyl and melamine are in sufficient concentration and of the type to attack the PC. The best source of information on chemical resistance is the material supplier for the PC. They have a large amount of reference data to help you in assessing the potential problem with chemical compatibility.

Good luck!
