Houseware applications

SAN (70% styrene, 30% acrylonitrile) has better heat and chemical resistance and is stiffer than PS. The optical clarity is not as good. SAN is used in a variety of houseware applications, particularly those things that will come in contact with food (chemical attack) and those that will end up in a dishwasher (heat attack). Coffee pots and throwaway tableware are good examples.

The important features of rigidity and transparency make the material competitive with polystyrene, cellulose acetate and poly(methyl methacrylate) for a number of applications. In general the copolymer is cheaper than poly(methyl methacrylate) and cellulose acetate, tougher than poly(methyl methacrylate) and polystyrene and superior in chemical and most physical properties to polystyrene and cellulose acetate. It does not have such a high transparency or such food weathering properties as poly(methyl methacrylate). As a result of these considerations the styrene-acrylonitrile copolymers have found applications for dials, knobs and covers for domestic appliances, electrical equipment and car equipment, for picnic ware and housewares, and a number of other industrial and domestic applications with requirements somewhat more stringent than can be met by polystyrene. 

Polymers of this type find application in toys and housewares and are of interest for medical applications and a wide variety of miscellaneous industrial uses. 

Even if the different consumer habits in the U.S.A. and Western Europe are taken into account, the comparison shows clearly that the various applications have undergone different developments. There has been a sharp drop - in relative terms -in the use of impact polystyrene for refrigeration - initially its main application - and for toys. In Europe, decorative articles play hardly any role. The packaging sector has made particularly big advances. Housewares, too, are on the way up. 

When the polypropylene (PP) technology finally ripened in the late 1950s, the chemicaL.industry was quick to harvest numerous applications. The primary attractions of this thermoplastic were the ease of molding or extruding it and its ability to hold color. Some of the familiar applications are automotive parts, luggage, pipe, bottles, fiber (particularly carpet face fiber and rope), housewares, and toys. 

Radical copolymerization of styrene with lCM-0% acrylonitrile yields styrene-acrylonitrile (SAN) polymers. Acrylonitrile, by increasing the intermolecular forces, imparts solvent resistance, improved tensile strength, and raises the upper use temperature of polystyrene although impact resistance is only slightly improved. SAN finds applications in houseware... 

HIPS is a thermoplastic that is widely used in packaging, toys, bottles, housewares, electronic appliances, and light-duty industrial components, because of its good rigidity and ease of coloring and processing. Flame retardant HIPS polymers find application in housings for business machines. Here we present recent issues and examples on applications of HIPS. 

Blow-molded products represent the biggest use of HDPE resins, around 40%. Packaging applications account for by far the greatest share of this market. These include such products as bottles (especially for milk, juice, and soap), housewares, toys, pails, drums, and tanks. 

Injection-molding products are the second largest application with approximately 20% of the HDPE market. These products includes housewares, toys, food containers, pails, crates, and cases... 

Injection molding is the second largest market for LLDPE, accounting for over 10% of its total consumption. Over half of the LLDPE consumed in injection-molding applications is used for housewares. 

Polypropylenes are available as molding powder, extruded sheet, cast film, textile staple, and continuous-filament yarn. They find use in packaging film molded parts for automobiles, appliances, and housewares wire and cable coating food container closures bottles, printing plates carpet and upholstery fibers storage battery cases crates for soft-drink bottles laboratory ware trays fish nets surgical casts and a variety of other applications. 

Housewares is another large segment of the use of polystyrenes. Refrigerator door liners and furniture panels are typical thermo formed impact polystyrene applications. Extruded profiles of solid or foamed impact polystyrene are used for mirror or picture frames, and moldings for construction applications. 

There are a wide range of applications that are made from SBC that may show up in the ordinary household. Some SBCs are used in appliances, housewares and office supplies. Owing to limitations of temperature resistance, chemical resistance, and abrasion resistance, the SBC may be blended with polymers such as styrene-methyl methacrylate (SMMA) to improve functionality. SBCs may also be seen in parts such as aquarium filter tanks, sewing machine dust covers, bird feeders, cake pan lids, pens, vacuum cleaners and computer accessories.
