In general, people's tableware is mainly made of ceramics. Because ceramics have the advantages of heat resistance and non-toxicity, they are well received by the public. However, ceramics are also easily broken and are often easily broken by children, so people hope to find a material that has the advantages of ceramics and is not light and brittle. As of now, this material has been born and has been used in tableware making materials, which is - melamine resin.
What is "melamine resin"? In simple terms, it is a thermosetting resin formed by using a synthetic synthesis technology to bond melamine and formaldehyde through a polycondensation reaction at a high temperature. The newly synthesized material is durable and durable. It is not easy to break, and can be made into a variety of colors, so it is very popular. However, when people hear about its craftsmanship and synthetic materials, it may not be as good as it is.
As we all know, melamine and formaldehyde are deeply criticized by the public because their past is not glamorous, but they become "cross-street mice" in synthetic materials, which is because they are harmful to the body because they are very strong.

In fact, the chemical reaction is so magical. Some seemingly harmful substances, after a chemical reaction, will turn into a substance that is harmless to the body. In the case of melamine and formaldehyde, both of them are toxic, but in the entire production process of the tableware, the raw materials are completely processed into a state-stable non-toxic component through a plurality of processes.
Of course, this kind of tableware made of melamine resin is not completely harmless, and it needs certain conditions. For example, the highest temperature limit of melamine resin is 120 degrees Celsius. If it exceeds this temperature, it will decompose and re-form formaldehyde and melamine. Therefore, it is not recommended to put melamine resin tableware when it is used. Heating in a microwave oven, etc., is definitely harmful to the body.
