What Are The Plastic Components Found in Home Appliances?

External Plastic Components
Main Housings: The primary casings for appliances such as televisions, washing machines, air conditioners, microwave ovens, and vacuum cleaners; typically made of ABS or HIPS to balance surface gloss with impact resistance.
Operational Components: Door handles, knobs, buttons, switches, decorative trim, and display panels; commonly made of ABS, PC, or PMMA to meet aesthetic and functional requirements.
Bases and Supports: Bases for rice cookers, electric heaters, and small appliances; often made of PP due to its low cost and good toughness.
Protective and Auxiliary Parts: Back panels, air outlet grilles, light covers, and transparent viewing windows; commonly made of PC, AS, or GPPS to balance light transmission with protective performance.

 

Internal Plastic Components
Storage and Containment Parts: Refrigerator liners, door liners, crisper drawers, and washing machine inner tubs; commonly made of HIPS, PP, or GPPS for low-temperature resistance and impact strength.
Thermal Insulation Parts: Polyurethane foam insulation layers within refrigerator doors and cabinets; these are core insulation components characterized by extremely low thermal conductivity.
Transmission and Structural Parts: Internal gears, bearings, bushings, hinges, and sliders; commonly made of POM or PA for wear resistance and dimensional stability.
Piping and Sealing Parts: Refrigerator drain hoses, door gaskets, and internal water transport lines; commonly made of PE or PVC for water and corrosion resistance.
Auxiliary Support Parts: Air duct covers, compressor housings, positioning plates, and connectors; commonly made of PP or ABS to provide structural support within the appliance.
