Melamine Plastic
Melamine is a thermosetting plastic. It is strong,
lightweight and hard, but can be scratched or broken or
cracked. It resists acids and alkalies, and most food
stains but can be stained. It also stands fairly warm
temperatures, but absorbs heat and softens if it gets
too hot so cannot be used in microwave ovens. It's used
for dinnerware, mixing bowls, laminated counter tops, and
other items. Melmac is a common trade name.
Avoid exposure to hot objects, and prolonged exposure
to boiling water.
Stains may be removed with commercial cleaners made
for melamine. Never use scouring powder or any other
abrasive.
