examples of melamine

This substance is used for the manufacture of: plastic products. Melamine and other nitrogen-rich oxytriazine compounds were added to feed ingredients to falsely boost the apparent protein levels and were used not only in pet food but also in livestock and fish feeds. Melamine phosphate and melamine pyrophosphate can also be used in paper, textiles, and wood laminates to effect fire-retardant barriers. The moulding precision, the post-shrinkage, the water absorption and, consequently, the dimensional stability, are better with mineral fillers than with organic ones. The information is aggregated from the data coming from REACH substance registrations provided by industry. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred. It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. Adhesives, following rigorous tests, allow joining. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. Is Melamine Tolerant to Hot and Cold Uses? Log in. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), outdoor use, outdoor use in long-life materials with low release rate (e.g. Generally, melamines behave acceptably although there can be a slight attack. MPP is today mostly used in combination with other FRs, such as metal phosphinates (see phosphinate chapter), metal hydroxides, and phosphates [28]. Non food-contact parts of beautiful aspect, for example toilet flaps, in urea-formaldehyde. Le règlement CLP a pour objet d’assurer que les dangers que présentent les substances chimiques soient clairement communiqués aux travailleurs et aux consommateurs de l’Union européenne grâce à la classification et à l’étiquetage des produits chimiques. When information is available in all sources, the first two are displayed as a priority. The continuous use temperatures in an unstressed state range from: For short durations, service temperatures can be much higher. Jahromi demonstrated that MPP depolymerizes at above 350 °C, inducing significant cross-linking (as evidenced by increase in viscosity) in PA 66 and leading to a drastic depolymerization of PA 6 (as evidenced by a decrease in viscosity) [29]. 1. Three modes of action of melamine are heat sink by absorbing heat during sublimation and cooling the substrate, inert gas, and dilution of the oxygen and fuel gases.56 The most important FR of this family is MC, available under the trade names Melapur MC, Aflammit, FerroFlam etc. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. Pssst… we can write an original … The parts should not be subjected to high stresses. The EC Number is the numerical identifier for substances in the EC Inventory. A large number of applications, sometimes up to 95%, are outside the framework of this book. This step generates wastewater that contains melam (Figure 4.42) as one of the main by-products. There is no known antidote for melamine intoxication. Decorative acoustic flagstones, suspended baffles, panels and partitions, soundproofing of roll-shutters boxes in melamine foam. Melamine is an important external adulterant for milk powders with negative health problems, including protein deficiency, kidney stones, and renal failure [64]. In dogs, the kidneys were greenish in color with greenish uroliths in the renal pelvis or bladder. Melamine foams: characteristic examples. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.
