What is melamine moulding compounds?
Melamine moulding compounds ( thermosetting plastics) are amino moulding compounds composed of melamine formaldehyde and alpha cellulose as filling material with the addition of lubricant , hardening agent & pigments.
Thermosets offer many advantages over basic thermoplastics and are suitable for compression , transfer or injection moulding.
They are produced in a precise, brilliant, light fastness and vibrant range of colors They are available in powder (which gives much better surface) or granular form.
Melamine moulding compounds are strong , glossy , very durable and highly resistant to staining. They have better resistanceto heat, solvents, chemicals, moisture, electricity and scratching than urea moulding compounds.

Applplications:
*Kitchen utensils and' kitchen ware, imitation ceramic dinnerware, tableware (plates, cups, saucers,ladles,spoons, , bowls, and dishes)
*Melamine crockery,melamine porcelain-like , tableware used by hotels,' schools, fast food restaurants, and households.
* Electrical appliance spares:switch, sockets, lamp holder.
