Advantages of Huafu Melamine Powder:
Huafu Chemicals has the ability to produce the corresponding melamine tableware raw material according to the product process characteristics of the specific country.
If the raw materials are not right, the engineer or the factory worker have to adjust the molding machine, adjust molding temperature, adjust the pressure which is really time-wasting because the factory workers will not be getting used to the new producing process. Nevertheless, this will increase the rate of defective products and that will cause huge loss in labor, time and money.
If you find the raw material supplier who doesn’t have the experience in the local market and haven’t cooperated, there will be many problems. Therefore, it’s necessary to find a reliable experienced melamine powder supplier like Huafu. We will offer a series of long lasting and one-stop service for you.

Physical property:
Melamine is a kind of thermosetting plastic with stable chemical properties at room temperature, compact structure and strong hardness. It is mainly used in wood, plastics, coatings and pharmaceutical industries.
Melamine powder in powder form with customized colors available: black, white, yellow, purple, red, ivory, bule, brown, orange, green etc
Applications:
It's widely used in tableware such as restaurant tableware, like bowl, cup, plate, bottle cap and daily appliances or electrical insulation components, such as high quality switch, socket plate, lamp holder, low-voltage appliances, instrument panel, etc.
Storage:
