1、 Classification of small household appliances
Small household appliances mainly include microwave ovens, rice cookers, electric irons, electric heaters, vacuum cleaners, electric fans, hair dryers, water dispensers, induction cookers, electric hotpots, electric kettles, air humidifiers, electric shavers, soymilk machines, Juicers, coffee machines, etc.
2、 Application status of plastic materials for small household appliances
1. Main materials of appearance parts
Abs: high gloss, easy to spray, but not resistant to high temperature;
PP: low cost, good liquidity, but poor dimensional stability;
PC: high strength, high temperature resistance, good transparency, but easy to crack;
Pc/abs alloy: excellent comprehensive performance, but high price.
2. Materials of main decorative parts
Transparent materials: transparent ABS, PMMA, PC, etc;
Electroplating material: electroplating grade ABS;
Film material: PET film, PC film.
3.3c core requirements for key parts
Main materials: flame retardant PBT, flame retardant PP, flame retardant PPO.
4. Core requirements for other key structural members
Main materials: POM, glass fiber reinforced nylon, PPS, PPA, Pei.
3、 Plastic materials commonly used in small household appliances
1. Microwave oven
Plastic parts on microwave ovens are mainly exterior parts that need heat resistance, such as shell, base, handle, knob, etc;
The selected plastics include pbt/pet GF, PBT GF, pc/abs, heat-resistant ABS, hips, heat-resistant PP, pp.
2. Rice cooker
Plastic parts on rice cookers are mainly outer parts that need heat resistance, such as shell, base, cover, handle, switch, etc;
The selected plastics are ABS, high gloss PP and PP.
3. Electric iron
The performance requirements of plastic materials used for electric soldering iron parts are mainly heat resistance, followed by impact strength and appearance;
ABS and high gloss PP can be selected for shell, handle and sink base;
Parts close to the heating zone need high heat resistance. PC, PA GF, pbt/pet GF, PBT GF and heat-resistant ABS can be used;
The requirements for heat resistance of the substrate are high, and pbt/pet GF and pet GF can be used to replace metal parts.
4. Electric heater
The plastic materials used on the electric heater need to be heat-resistant, especially the air outlet grille;
The selected plastic varieties include pbt/pet GF, pet GF, PC, pc/abs, heat-resistant ABS and heat-resistant PP.
5. Vacuum cleaner
Plastic materials used for vacuum cleaner components need to be antistatic to avoid dust collection. In addition, they also need good electrical performance, good rigidity, impact resistance, scratch resistance, good dyeing and gloss, especially the shell;
The selected plastics are ABS, hips and high gloss PP. Among them, the transparent part can be PC, as, GPPS.
6. Electric fan
The plastic parts used by electric fans mainly include fan blades, leaf covers, shell covers, knobs, etc;
The selected plastic varieties include ABS, hips, high gloss PP, PP GF and as GF.
7. Hair dryer
The selected plastics include pbt/pet GF, pet GF, PC, heat-resistant ABS and heat-resistant PP.
8. Water dispenser
The plastic parts on the water dispenser are required to be rigid, glossy and impact resistant;
The selected plastics are ABS, hips and high rigid PP.
9. Induction cooker, electric hot pot
The selected plastics are heat-resistant ABS and high gloss heat-resistant PP.
10. Electric kettle
The selected plastics include pc/abs, heat-resistant ABS and high gloss heat-resistant PP.
11. Air humidifier
The selected plastic varieties are: transparent part (PC, GPPS), opaque part (ABS, high gloss PP).
12. Juicer, soymilk machine
The selected plastic varieties are: transparent parts (PC, as, GPPS), opaque parts (ABS, high gloss PP).
13. Coffee machine
The selected plastic varieties are: transparent parts (PC), opaque parts (ABS, high gloss PP).
14. Electric shaver
The selected plastic varieties are: pc/abs, ABS, pp.
As mentioned above, PP, ABS, pc/abs, PC, PBT, pet, pbt/pet, etc. are generally used for plastic parts of small household appliances in the market. Not only are there many kinds of plastics used by different small household appliances, but also there will be differences in color, gloss, etc. even if the same small household appliance uses different plastics in different parts.
