Which feature makes Melamine Formaldehyde suitable for tableware?

Melamine Formaldehyde is particularly suitable for tableware primarily due to its scratch resistance and water resistance. These characteristics are vital for items that are frequently used for serving and consuming food, as they help maintain the appearance and integrity of the tableware over time.

The scratch resistance ensures that the surface of the tableware does not easily get damaged by utensils, which can be common in everyday use. This advantage allows the tableware to look new and clean for longer periods, enhancing its aesthetic appeal.

Water resistance is equally important because it prevents moisture absorption, making the material easier to clean and more hygienic. This property helps prevent the growth of bacteria and ensures that the tableware can be safely used for various types of food and beverages without degrading over time.

The other options do not pertain to the characteristics that make Melamine Formaldehyde advantageous for tableware use. For instance, heat resistance and flexibility are useful, but not as critical in everyday tableware compared to scratch and water resistance. The ability to dissolve in heat and malleability when heated are not features of Melamine Formaldehyde; in fact, it is a thermosetting plastic, which means it should not melt or deform under high temperatures once set.
