Is Melamine formaldehyde a polymer?
Yes melamine-formaldehyde was one of the first polymers.
If the dinnerware does not state 100 Melamine then what other chemicals are combined to manufacture it?
When you purchase melamine dinnerware, make sure you find out whether it is made of 100% melamine. There are a lot of melamine dinnerware manufacturers who use another material called urea-formaldehyde to replace or mix with melamine-formaldehyde to reduce cost. These are inferior quality melamine and it should also be called as imitation products because they are not made of 100% melamine (melamine formaldehyde. 100% melamine tableware are made of purely melamine formaldehye which is…
A polymer that does not soften when heated is called a "thermosetting" polymer. (plastic is a word that means flexible with a viscoelastic flow) Examples include Baekelite, and Melamine-formaldehyde. Usually the polymerization reaction is carried out to about 50-60% completion to form a viscous resin. This is then moulded and heated to complete the polymerization. The final structure is heavily cross-linked and quite rigid.
