Does melamine dinnerware contain formaldehyde and melamine

  The main component of melamine tableware is melamine resin, and the raw materials of melamine resin are melamine and formaldehyde. These two substances are poisonous substances that people are afraid of, so can the melamine tableware at home still be used?

  Melamine resin is a very stable polymer formed by the reaction of formaldehyde and melamine, and it will not decompose into formaldehyde and melamine by itself. However, this reaction often cannot achieve 100% conversion efficiency, and the formaldehyde that has not completely reacted may volatilize.

  There are two main factors that affect formaldehyde volatilization:

1. Plastic content

2. Operating temperature

  In the process of producing tableware, manufacturers will add plastic to melamine resin for shaping. Plastic are a type of small molecules used to improve product quality and make plastic products more fluid during processing. However, they will also make free formaldehyde in the product more easily precipitated. The specific amount will vary depending on the materials used.

  Among the common imitation porcelain bowls on the market, the materials are divided into A1 melamine, A3 melamine, A5 melamine and A8 melamine according to the different ratios of plastic and melamine resin.

  A1 and A3 Melamine:

The content of melamine resin is low, but the content of plastic is high, so A1 and A3 melamine cannot actually be used in tableware. They are highly toxic, not resistant to high temperatures or corrosion, and will release formaldehyde at higher temperatures, especially when serving hot soup, the formaldehyde will dissolve directly into the dishware.

  A more toxic inferior imitation porcelain tableware is made of urea-formaldehyde resin to impersonate melamine resin. This material will decompose and release formaldehyde gas at 80℃, so it is not allowed to come into direct contact with food according to national standards.

  A5 and A8 Melamine:

A5 Melamine: contains 70% melamine resin, and the other 30% is additives, starch, etc.

A8 Melamine: contains 100% melamine resin, non-toxic and odorless.

  In the range of -30℃～150℃, the amount of formaldehyde released by qualified melamine tableware is negligible and will not affect human health. Therefore, please pay attention to the temperature when using it and do not heat it.

  Tips for using tableware

1. The safest way to buy melamine tableware is to buy it through formal channels (such as supermarkets and shopping malls), and remember not to buy it just because it is cheap. Pay attention to the temperature when using it and do not heat it.

2. Among plastic tableware, polypropylene is the best choice, but you should pay attention to the conditions of use and replace it in time.

3. Although glass and ceramics are fragile, they are safer than plastic and melamine tableware.
