In recent years, with the receding of home appliances in Europe and the United States, China has gradually become a global home appliance manufacturing. Therefore, the demand for plastic materials is also increasing, plastic has become the second type of raw materials after steel in the home appliance industry, and it is also the fastest growing material. At present, China's main household appliances, not small appliances or electricity, plastic figure are indispensable. So today, let's take a look at what plastics are used in home appliance shells? Most of the plastics used in the manufacture of home appliance housings are thermoplastics, accounting for about 90%. After collection, there are the following: HIPS impact resistant polystyrene ABS acrylonitrile butadiene styrene copolymer PC polycarbonate PPO polyphenyl ether MPPO (modified benign polyphenyl ether) =PPO+HIPSPVC polyvinyl chloride A, the characteristics of household appliances with plastic general plastics: ABS, HIPS, GPPS, PP, etc.; High surface requirements: color, finish, hardness, printing performance, etc. Good mechanical properties, thermal properties, aging resistance; Flame retardant performance, electrical insulation performance; Better processing performance, dimensional stability; The price is cheap. 1.ABS and HIPS have good strength and toughness, high surface, wear-resistant, excellent comprehensive performance, and are the most used plastic varieties in home appliances. The annual consumption of ABS/HIPS in China's household appliance industry is more than 1 million tons, which is the largest variety of household appliance plastics. Used for TV, radio, tape recorder, fan, vacuum cleaner and other home appliance shell, refrigerator liner, drawer and so on. At present, the commonly used ABS suppliers are: Chi Mei, Kumho, Jihua; And HIPS for Yang Ba, Basf, Chi Mei and so on. 2.PPHIPS and ABS are the first plastic materials used in household appliances, due to the high price of HIPS and ABS resin, foreign countries have gradually developed PP (polypropylene) modified materials suitable for household appliance parts, and partly replace the application of HIPS and ABS resin in household appliances with its advantages of low cost, light weight and good performance. As one of the five plastic materials, PP has excellent comprehensive performance, good chemical stability, good molding processing performance and relatively low price; However, it also has some shortcomings such as low strength, modulus, hardness, low temperature impact resistance, large shrinkage and easy aging. Therefore, it must be modified so that it can adapt to the needs of the product. The modification of PP materials is generally through the addition of mineral reinforcement toughening, weather resistance modification, glass fiber reinforcement, flame retardant modification, super tough modification and other ways, each kind of modified PP has a large number of applications in the field of household appliances. Good strength and toughness, heat resistance, fatigue resistance, many varieties, low price, easy to modify, is the use of household appliances after ABS plastic varieties. Used for washing machine inside and outside bucket, base. Cover plate, switch box, fan motor cover, refrigerator back cover plate, motor bracket cover plate and a small number of fans, TV shell, refrigerator door liner, drawer, etc. Currently commonly used high mobility PP: Yanhua K7726, Yanhua K9020, Shanghai Petrochemical M2600R, modern M1600, Exon AP03B, etc.; The middle liquidity is common: Singapore AW564, Saudi PP520, Exxon AP3N and so on. The main direction of PP materials at present is: 1) High rigidity, high PP This product will be possible to replace PS and ABS in some home appliances, especially small home appliances. 2) Halogen-free flame retardant PP The implementation of the EU RoHS law, countries attach importance to environmental protection, the research and development of halogen-free flame retardant PP is urgent, and the market prospect is broad. 3) Long glass fiber reinforced PP Ordinary short glass fiber reinforced PP, because the glass fiber contains short, easy warping, low impact strength, easy deformation when heated, long glass fiber can overcome the above defects of short glass fiber, and the product has a good surface, higher use temperature, higher impact strength, can be applied to refrigerators and kitchen appliances with relatively high heat resistance. 4) Antibacterial PP This plastic is a new functional polymer material with its own bactericidal and antibacterial properties, which can be applied to the inner liner of washing machine and the plastic parts in refrigerators, etc., with broad prospects. 3.PS and SAN have good transparency, good rigidity, high surface hardness, stable size, good strength and toughness, good surface decoration, low price, and are the most used transparent plastic varieties in home appliances; Used for refrigerator fruit and vegetable box, egg rack, tray, tape box and other transparent parts. 4.PVC Rigid PVC is a material with good flame retardant properties, chemical resistance, UV resistance, and cost advantages, which has been proven in the North American home appliance market with strict requirements, and has successfully replaced other polymer materials, such as flame retardant ABS, PC+ABS, PC. In fact, rigid PVC has been continuously promoting the innovative design of home appliance housings, such as metal appearance, IML mold decorative box glass packaging. This kind of source is rich, the price is low, the applicability is strong, the adaptability is wide, but the current use in home appliances is narrow; Mainly used for refrigerator door seals and various household appliance sealing sleeves; In foreign countries, it is used to replace part of PP, ABS and HIPS for injection molding and ABS alloy preparation of home appliance shell. 5.PC the best toughness of engineering plastics, good creep resistance, good heat and cold resistance, long-term use temperature of -60 ~ 120℃, aging resistance, good transparency. Used for hair dryer, electric heater shell, gear, rack, transparent cover shell, CD, washing machine side cover, hot water contact parts such as refrigerator fruit and vegetable box, egg rack, tray, tape box and other transparent parts. 6. Other magnetic plastics: including structural magnetic plastics (such as Japan's PPH "polybis-2, 6-pyridyl octyl dinitrile" iron sulfate) and composite magnetic plastics (magnetic powder and plastic mixture), used in motors, electrical parts, refrigerator seals, etc.; Electromagnetic shielding plastics: including structural shielding plastics (such as polyacetylene) and composite shielding plastics, volume resistance in 10-2 ~ 10-11ω.cm, used for electrical shell and circuit components. In addition to the above mentioned plastics, perhaps we also see some elastomers, say, TPE, etc. The plastic commonly used in the above household appliances, which kind of plastic do you sell? In other words, as a household appliance company or parts company, what kind of plastic do you use?
