Never heat food or drinks in melamine, including in the microwave (the risk of migration is higher when heated). Wanneer je Melamine samenvoegt met formaldehyde, krijg je een goedje dat je gemakkelijk vorm kan geven wanneer verhit. Uses. When combined with formaldehyde, melamine becomes melamine resin, a substance that can be molded to create tableware when heated. Structures were determined with IR, 1 H‐NMR, and 13 C‐NMR spectroscopies. According to "Handbook of Plastics Technologies," melamine formaldehyde is used extensively in automotive coatings, epoxy coatings and polyester appliance coatings. Avoid serving highly acidic foods, which also increases the chance of migration. As a result, there is a risk of melamine and formaldehyde discharge into foods prepared or stored in melamine-containing dishes, bowls, and other products in the home. Melamine formaldehyde is a thermosetting plastic and cannot be melted. The effects of mole ratio of formaldehyde and melamine (F/M), solution pH, reaction temperature and time on the foaming melamine-formaldehyde resin (MF resin) with caprolactam as modifier were investigated by orthogonal experiment design where the solid content and the viscosity of the resin, the density and the size uniformity of the foam resin were used as performance evaluation parameters. All melamine formaldehyde uses wholesalers & melamine formaldehyde uses manufacturers come from members. So, whether it is the ink that we use in our printers, or the one used for printing books, formaldehyde is a key ingredient.
