After reaction with formaldehyde, melamine becomes melamine resin, which can be molded into tableware when heated. Maybe you are not familiar with melamine plates; you may have seen or used melamine plates, which are generally used in restaurants and hotels. With the popularity of melamine tableware, many people have questions about the difference between melamine tableware and plastic tableware. Now, let's take a look at PP and the difference between them.
PP is a thermoplastic material, which its raw material can be recycled and melted. Melamine tableware is a thermo-setting plastic which the powder can only be used one time without any recycling. The differences are as follows:
1. Smell: pure melamine has no smell, PP is mild smell.
2. Density: can judge easily according to the density on the product data
3. Ignition test: melamine is generally V0 level and more difficult to burn. PP is flammable.
4. Hardness: melamine is similar to porcelain, melamine products is harder than PP
5. Safety: pure melamine (melamine formaldehyde resin) is safer than PP (polypropylene)
