Melamine-formaldehyde polymers properties

Melamine-formaldehyde polymers are widely used in the form of high-quality molded dinnerware. The applications take advantage of their heat resistance and water-white color. Melamines retain their properties at low temperatures, and have very good arc- and track resistance. Melamines are also often used where resistance to caustic is required. However, melamine laminates have poor dimensional stabiUty, particularly when the part is exposed to alternating cycles of high and low humidity. [Pg.313]

Together, antifreeze, PET, and polyester polymers account for about 98% of the ethylene glycol produced in the United States. It is also used sometimes as a deicer for aircraft surfaces. The two hydroxyl groups in the EG molecule also make EG suitable for the manufacture of surfactants and in latex paints. Other applications include hydraulic brake fluid, the manufacture of alkyd resins for surface coatings, and stabilizers for water dispersions of urea-formaldehyde and melamine-formaldehyde The hygroscopic properties (absorbs moisture from the air) make EG useful as a humectant for textile fibers, paper, leather, and adhesives treatment. [Pg.153]

The synthesis of phenolic-formaldehyde and melamine-formaldehyde resins in the presence of fumed silica allows obtaining porous organic materials with a differentiated porous structure and surface properties. The pore characteristics of the studied resins in dry state were determined from nitrogen adsorption isotherms. The differences in surface character of the synthesized polymers were estimated satisfactorily by XPS spectra showing the presence of various functional groups. The adsorption/desorption mechanism of water and benzene on the investigated porous polymers was different due to differentiated hydrophobicity of the bulk material. [Pg.497]
