Study of melamine and formaldehyde migration from melamine tableware

European Food Research and Technology, 2016
Two HPLC–UV rapid methods have been developed to quantify and identify melamine, ammeline, ammelide and formaldehyde in samples of melamine plastic kitchenware. Eighteen samples of melamine articles purchased at various markets in Galicia (Spain) and Quito (Ecuador) were analyzed. Melamine analysis was carried out using a HILIC column (150 × 3 mm, 3 µm

Migration of melamine and formaldehyde from tableware made of melamine resin

Food Additives and Contaminants, 1986
Migration of melamine and formaldehyde into food-simulating solvents from cups made of melamine resin was studied under various conditions. Little migration of melamine was observed in any unused cups kept at 60 degrees C for 30 min, room temperature (26 degrees C) for 1 h or cooled at -20 degrees C for several days.

Production of melamine fortified urea‐formaldehyde resins with low formaldehyde emission

Journal of Applied Polymer Science, 2011
AbstractMelamine can be incorporated in the synthesis of urea‐formaldehyde (UF) resins to improve performance in particleboards (PB), mostly in terms of hydrolysis resistance and formaldehyde emission. In this work, melamine‐fortified UF resins were synthesized using a strong acid process.

Rheokinetical behavior of melamine‐formaldehyde resins

Polymer Engineering & Science, 1999
AbstractThe effects of cure temperature and amount of catalyst on the rheokinetical behavior of a melamine‐formaldehyde (MF) thermosetting system is investigated using a dynamic mechanical technique similar in nature to Torsion Impregnated Cloth Analysis (TICA) and Torsional Braid Analysis (TBA).

Melamine-formaldehyde compounds—I The alkaline decomposition of methylol melamines and methoxymethyl melamines

European Polymer Journal, 1969
Abstract The acid catalysed decompositions of trimethylol melamine (TMM), hexamethylol melamine (HMM), methylated trimethylol melamine (TMM-Me) and hexamethoxymethyl melamine (HMM-Me) have been investigated kinetically. The deompositions of TMM and HMM are subject to general acid catalysis. The results suggest that the activation of TMM and HMM takes

Melamine formaldehyde foam with reduced formaldehyde emission.

2020
Method for lowering the formaldehyde emissions of melamine/formaldehyde polymer moldings, films or fibers by impregnating the melamine/formaldehyde polymer moldings, films or fibers with an aqueous solution of at least one formaldehyde scavenger.
