1, Application of plastic materials in small household appliances
① Main materials of appearance parts
ABS: high gloss, easy to spray, but resistant to low temperature;
PP: Low cost, good fluidity, but poor dimensional stability;
PC: High strength, high temperature resistance, good transparency, but easy to crack;
PC/ABS alloy: excellent comprehensive properties, but expensive.
(2) the main materials of decorative parts
Transparent materials: transparent ABS, PMMA, PC, etc.
Electroplating material: electroplated ABS
Film materials: PET film, PC film.
③ Core requirements of 3C key components
Main materials: flame retardant PBT, flame retardant PP and flame retardant PPO.
④ Core requirements of other key structural parts
Main materials: polyformaldehyde, glass fiber reinforced nylon, polyphenylene sulfide, PPA and Pei.
2. Selection of common plastic materials for small household appliances
(1) microwave oven
The plastic parts on the microwave oven are mainly external parts, including shell, base, handle, knob and so on. This requires heat resistance.
The selected plastic varieties are PBT/PET+GF, PBT+GF, PC/ABS, heat-resistant ABS, HIPS, heat-resistant PP and PP.
(2) rice cookers
The plastic parts on the rice cooker are mainly external parts, including shell, base, cover, handle, switch and so on. This requires heat resistance. The selected plastic varieties are ABS, high-gloss PP and PP.
(3) Electric iron
The performance requirements of plastic materials for electric iron parts are mainly heat resistance, followed by impact strength and appearance.
The shell, handle and sink base can be ABS and high-gloss PP;
Parts near the heating area require high heat resistance, and PC, PA+GF, PBT/PET+GF, PBT+GF and heat-resistant ABS can be used.
The base requires high heat resistance, and PBT/PET+GF and PET+GF can be used instead of metal parts.
(4) electric heater?
The plastic material used on the electric heater requires heat resistance, especially the style grid.
The selected plastic varieties are PBT/PET+GF, PET+GF, PC, PC/ABS, heat-resistant ABS and heat-resistant PP..
(5) Vacuum cleaner
The plastic material used for the parts of vacuum cleaner requires anti-static to avoid dust absorption. In addition, it also requires good electrical performance, good rigidity, impact resistance, scratch resistance, good dyeability and luster, especially the shell.
