Applications
Melamine powder, as a thermosetting plastic made of melamine and formaldehyde co-condensation, has been widely used in many downstream industries due to its unique physical and chemical properties.
1. Tableware and Container Manufacturing
Due to its excellent heat resistance, flame retardancy and good mechanical strength, melamine powder has become an ideal material in the field of tableware and container manufacturing. Especially in the field of imitation porcelain tableware, the application of melamine powder is particularly extensive. Compared with traditional ceramic and glass tableware, melamine tableware is not only beautiful in appearance, bright in color, but also lighter in weight and durable. With the implementation of the natural forest ban and disposable tableware ban policy, the market demand for melamine imitation porcelain tableware continues to grow, which has brought broad development space for the melamine powder industry.
2. Electrical Field
In the electrical field, melamine powder also shows its unique advantages. Due to its excellent electrical properties under wet and high temperature conditions, good arc resistance and scratch resistance, melamine powder is widely used in the manufacture of low and medium voltage electrical components.
3. Mahjong
Melamine powder is also often used to make mahjong. Melamine made mahjong is not only comfortable but also environmentally responsible because this material has good physical qualities and a nice hand feel. Furthermore, melamine mahjong is highly resistant to wear and tear, and able to retain its original appeal when played regularly. It also won't become contaminated with extraneous objects, making it a great choice for family entertainment.
