Urea-formaldehyde Resin

Name:
Urea-formaldehyde Resin
Detailed information:
An important class of amino resin. Urea and formaldehyde are united in a two-stage process in the presence of pyridine, ammonia, or certain alcohols with heat and control of pH to form intermediates (methylolurea, dimethylolurea) that are mixed with fillers to produce molding powders. These are converted to thermosetting resins by further controlled heating and pressure in the presence of catalysts. These were the first plastics that could be made in white, pastel, and colored products.

Use:

Scale housings, dinnerware, interior plywood, foundry core binder, flexible foams, insulation.See amino resin; Melamine Resin.
