TV cabinets

The importance of adequate support by database reference material is well illustrated with the following case. After chromatographic separation (TLC, CC), the combination of >H/13C NMR, DI-MS (El), FTIR and HPLC (IJV/VIS, DAD and MS) a flame retardant in a Japanese polypropylene TV cabinet on the European market was identified as tetrabromobisphenol-,S -bis-(2,3-dibromopropyl ether) (TBBP-S) [168]. The result was verified by synthesis of reference material the product was finally identified as Non Nen 52 from Marubishi Oil Chemical Co., Ltd (Osaka), not registered in any spectral database. 

Structural foams are made of a cellular core with a dense skin. The technique is used for industrial and aesthetic goods for the automotive, electronics, household appliance and aeronautics sectors, such as housings of machines, TV cabinets, computer housings, roofs for caravans or ships, hard tops of 4WD (Jeep), luggage boxes, parts for washing machines. Structural foams are processed by thermoplastic injection moulding using ... 

Approximately 11.8 million pounds of hexabromobiphenyl were used in commercial and consumer products in the United States, most in the production of plastic products with an estimated use life of 5 10 years (Neufeld et al. 1977). Since the cessation of production, all of these products, such as TV cabinet and business machine housings, must have been disposed ofby land filling or incineration (Neufeld et al. 1977). The formation of polybrominated dioxins (PBDDs) and polybrominated dibenzofurans (PBDFs) during the incineration of plastics containing PBBs remains a distinct possibility (Luijk and Covers 1992 O Keefe 1978).

Since mold pressures in RIM processes are usually below 100 psi (0.69 MPa), mold-clamp-pressure requirements can accordingly be low. Most RIM equipment is in the 25-100 ton range. Depending upon production quantity and quality requirements, molds for RIM may be made from aluminum-filled epoxy for low production, or from cast or machined aluminum or chrome-plated steel for longer runs. Molds must be heated to 120-160°F (49-71°C). Applications include automobile bumpers, radio and TV cabinets, furniture and business-machine housings (5).

Disposable cups and glasses for hot (only PS foam) and cold drinks, electrical fittings, CD case (jewel box), Airfix model kits, food containers, coat hangers, hair combs, TV cabinets, expanded foam packaging, foam thermal insulation, foam ceiling tiles, insulated food containers. 

The failure of electrical appliances or fixtures can initiate smouldering, which conld lead to localised fires, snch as are simulated in, for example, DEN EN 60695-11-5 [13], through, for example, flame exposure from a Brmsen burner. Depending on the application (TV cabinets, cables and so on), other fire sources are used.

Firemaster 2100 is a general-purpose brominated compound not based on diphenyl ether chemistry. It is supplied as a uniform white powder suitable for formulations requiring white or light-coloured products. Use is foreseen in applications such as TV cabinets, foam insulation, wire and cable, appliances and textiles. 

Studies in the US in the past, mainly through the auspices of the National Institute of Standards Technology (and its predecessor. National Bureau of Standards), have shown that the overall costs, in terms of damage, health and environmental considerations, of non-flame retarded TV cabinets, and other consumer items, that are involved in fires is much higher than those associated with a properly formulated and flame retarded material used for the same purposes. 

High-density polyethylene (HOPE) is composed of linear chains that are closely packed. This type of polymer is rigid, hard, and tough. Milk jugs, toys, and TV cabinets are made from HOPE. The Hula-Hoop was one of the first products ever made from this form of polyethylene. 

Should swirl marks and surface roughness be undesirable in the finished product, e.g. audio or TV cabinets, then secondary operations become necessary. These usually involve spraying or foiling. 

ABS/PVC blends have found use in applications requiring flame-retardant characteristics, e.g., in appliances, business machine housings, TV-cabinets, electrical and electronic components. The blends show excellent moldability. 

GIM can be used to cost-effectively produce complex shapes that require high-quality surfaces, offering designers a high level of freedom. Examples here include door handles for cars or other plastic car parts such as mirror housings, bumpers or door modules. GIM parts are not restricted to the automotive industry, however. They can also be foimd in other areas, for example as handles in various household appliances (e.g. refrigerators), TV cabinets or crates for carrying bottles. 

PyGC-MS enables differentiation between various brominated flame retardants. Pyrograms of the reference materials (pure FRs) need to be compared with that of the sample to be examined in order to identify the flame retardant class. Selection of the pyrolysis temperature is most important. A compromise between mobilisation of the flame retardants and minimisation of thermal reaction products has to be found. Flame retardants were identified in EPR/TBBA, ABS/TBBA, PBT/TBBA, PP/PBDE, HIPS/PBB, using an optimised pyrolysis temperature (430°C) for these systems [791]. PyGC-MS was also used for polymer and additive (FR) characterisation of a Japanese TV cabinet [792]. Figure 2.36 shows the additive fragments isolated, together with a proposed (sub)structure, sufficient to identify the flame retardant as tetrabromobisphenol-5 -bis-(2,3-dibromopropylether) (TBBP-S) on the basis of patent search. 

Adhesives enter into the manufacture of both residential and commerical wood and metal furniture, including office furniture, counter-tops, vanities, stereo speakers, TV cabinets, kitchen cabinets. More than a dozen types of adhesives are employed PVAC is the largest (Table 18). 

Urea-formaldehyde, urea-furfural-formaldehyde, and urea-resorcinal mixtures form thermosetting resins that are used in molding applications such as radio and TV cabinets, in the treatment of paper and fabrics, and as adhesives for bonding wood. The resins are nearly colorless but opaque, and may be pigmented as desired. They improve crush and crease resistance in textiles, and impart wet strength to paper and paper coatings. A small amount of acid, or acid-generating catalysts, may be added to make the resin set.
