CAS 108-78-1 Melamine and formaldehyde are two distinct chemicals that are combined to make a plastic resin.
What is Melamine powder?
CAS 108-78-1 Melamine is an organic compound with the chemical formula C₃H₆N₆. It is a nitrogen-rich substance that is often recognised by its white, crystalline powder appearance. Its nitrogen content makes melamine a valuable ingredient in the production of plastics, laminates and certain types of dinnerware. Due to its chemical stability, it is also used in flame retardants and fertilisers.

What is Formaldehyde (CAS 50-00-0) ?
Formaldehyde is a colorless, pungent gas with the chemical formula CH2O. It is known for its strong smell and is one of the simplest forms of aldehydes. Formaldehyde is commonly used as a disinfectant, preservative, and adhesive component.
What is the difference between melamine and formaldehyde?
| Feature | Melamine (C₃H₆N₆) | Formaldehyde (CH₂O) |
|---|---|---|
| Identity | An organic base, a solid triazine compound. | A simple aldehyde gas, dissolved in water as formalin. |
| Role in Resin | Provides a nitrogen-rich, rigid, triazine ring structure. | Provides reactive -CH₂- groups to link molecules (acts as a cross-linker). |
| Final Product | When reacted together under heat and pressure, they form Melamine-Formaldehyde (MF) Resin, a durable thermosetting plastic. |
