Melamine Formaldehyde - MF Melamine Cellulose Filled

Advantages

Easily coloured (unlike Phenolics). Taste and odour free. Good resistance to solvents - stain resistant in general, although dependent upon filler choice. Electrical properties relatively unaffected by high humidity (unlike Phenolic). Self-extinguishing.

Disadvantages

Inferior to Phenolic in dimensional stability in hot dry conditions. More expensive than Urea or Phenolic. Limited resistance to concentrated acids and alkalies.
