If the dinnerware does not state 100 Melamine then what other chemicals are combined to manufacture it?
When you purchase melamine dinnerware, make sure you find out whether it is made of 100% melamine. There are a lot of melamine dinnerware manufacturers who use another material called urea-formaldehyde to replace or mix with melamine-formaldehyde to reduce cost. These are inferior quality melamine and it should also be called as imitation products because they are not made of 100% melamine (melamine formaldehyde. 100% melamine tableware are made of purely melamine formaldehye which is guaranteed food safe and able to withstand high temperatures whereas urea-formaldehye is not suitable to for food contact products because they cannot withstand high temperatures. Therefore they can only be used on non-food contact products such as electrical appliances. Therefore, it is not that all melamine dinnerware ares unsafe. It is those inferior quality melamine products (mixed with urea-formaldehyde) that is not safe for manufacturing dinnerware.
What is Monomer of melamine?
1,3,5-triazine ,2,4,6-triamine and formaldehyde
Which moler ratio of urea formaldehyde is best for chipboard?
An improved method for the preparation of particleboard wherein a cellulose-containing particulate material is provided with a urea formaldehyde resin bonding agent and thereafter shaped and hardened at an elevated temperature and pressure. The bonding agent used is a urea-formaldehyde resin solution additionally containing melamine in an amount of 1.0 and 10 percent by weight, relative to the total amount of resin solids. The molar ratio of formaldehyde to mole equivalents of amino groups in the bonding agent is in the range of between 0.500:1 and 0.575:1.

What kind of plastic is melamine?
Melamine plastic, also known as melamine formaldehyde, is a hard, thermosetting plastic material made from melamine and formaldehyde. Melamine is often used in kitchen utensils and plates and became very popular in the late 1950's and 60's.
What material is mixed with melamine formaldehyde resin to make a compound wich is suitable to manufacture 100 percent melamine tableware?
pulp
How do you use melamine formaldehyde for textile sizing agent production?
Melamine formaldehyde is a firm setting agent plastic agent. Melamine is the largest constituent of high-pressure laminates like Formica. Melamine-resin tile can also be used as whiteboards. Since it is a hardening agent it is not used for making things larger or changing its size.
How to manufacture urea formaldehyde resin?
The laboratory preparation of urea-formaldehyde with melamine formaldehyde resin added is meant to modify the urea-formaldehyde resins in order to get good performance with a low formaldehyde emission. The optimal percentage of the melamine resin is 20 percent of the entire solution.
What kind of adhesives are used in engineered hardwood?
There are many different adhesives used for engineered hardwood. Urea-formaldehyde resins, phenol-formaldehyde resins, melamine-formaldehyde resin, and polyurethane resins are also adhesives used for engineered hardwood.
What are the different uses of paraformaldehyde in details?
Paraformaldehyde is a solid form of formaldehyde. ithas the same uses as formaldehyde. Like Formaldehyde, Paraformaldehyde also reacts with phenol, urea, melamine or resorcinol and produce resins used as binders. Regards Sharad Madhukar Koparkar India
