High and low voltage electrical engineering, switches, distributor boxes, meter cases, regulator cases, hoodings of small electric motors, fuse boxes in melamines. See also Table 4.31. Figure 4.15. If the substance is covered by more than one CLH entry (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners) and outdoor use. Examples include recommended measures on fire-fighting, transport and recycling and disposal. The EC Number is the numerical identifier for substances in the EC Inventory. In a fire situation, melamine resins produce a relatively low amount of smoke at a relatively low level of toxicity. They are classified according to the formulation, properties or type of application: Cellulose, mineral, glass fibre, wood flour, organic/mineral mixed fillers …, Food contact, reduced water absorption, improved electrical properties, arc resistant, high temperature, low sensitivity to cracking, fireproofed …. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). Unhardened moulding sheets for compression moulding. melamine color sample are versatile enough to be worn by virtually anyone, including women, men, and kids of all ethnicities and ages. 0. melamine laminate, stone, stainless steel and solid surfaced worksurfaces. Release to the environment of this substance can occur from industrial use: as an intermediate step in further manufacturing of another substance (use of intermediates), in the production of articles, for thermoplastic manufacture, in processing aids at industrial sites and as processing aid. The formation of cyclopentanone during the degradation of PA6.6 and cross-linking of cyclopentanone with MC degradation products could be the origin of this difference. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. Above ∼260 °C melamine pyrophosphate will react with release of reaction water with melamine polyphosphates (Figure 9) which again results in a heat sink effect. BASF has developed a heat and flame resistant fibre “Basofil”, which is actually produced by MLM. Melamine has been available commercially since the late 1930s and no significant reports of adverse health effects in humans have been found. Substances which have been registered and can be placed on the EEA market by those companies with a valid registration. The phosphoric acid along with the polymer also works to form a char around the fuel source (polymer), thus reducing the amount of oxygen present at the combustion source. Aesthetics, beautiful aspect, brilliancy, clear colours, scratch- and abrasion-resistant surface; good electrical properties including arc resistance, fairly good mechanical properties (“unbreakable” dishes); generally good behaviour in the presence of many organic chemicals (notably the detergents); self-extinguishing grades (UL ratings); food-contact grades for the melamines which, moreover, offer a better water and moisture resistance than the urea-formaldehydes; more attractive price for urea-formaldehydes. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. The interaction between the two plants is important for waste recycle. It is deaminated to the oxytriazine structural analogs ammeline, ammelide, and cyanuric acid. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). The continuous use temperatures in an unstressed state range from: For short durations, service temperatures can be much higher. Table 4.30 gives some general indications, which would have to be verified by consultation with the producer of the selected grades and by tests under operating conditions. Melamine phosphate and melamine pyrophosphate can also be used in paper, textiles, and wood laminates to effect fire-retardant barriers. Non food-contact parts of beautiful aspect, for example toilet flaps, in urea-formaldehyde. ‘Sulphonated melamine formaldehyde condensate in the form of an aqueous solution was used.’ ‘The direct pressure laminate is basically a one step process, whereby all the layers are fused directly to the core at the same time, and impregnated with melamine resins using heat and pressure.’ In addition, products bonded with MF resins seem to be less susceptible to the release of formaldehyde than are products bonded with UF resin. Please report examples to be edited or not to be displayed. In dogs, the kidneys were greenish in color with greenish uroliths in the renal pelvis or bladder. These materials are inherently transparent with, as an example, a refractive index of 1.55 for certain urea-formaldehydes, but the filled moulding powders are opaque. The source of the information is mentioned in the introductory sentence of the hazard statements. Rumbeiha, D.B. De plus amples informations sur la pratique multilingue de l'ECHA sont disponibles.
