With the social development and consumer demand, plastics are more and more widely used in the field of home appliances. In household appliances, ABS, abs/pvc, as, PC, POM, MPPO, pet, reinforced PBT, PSF and other engineering plastics are commonly used. Why are these engineering plastics? (ABS is not an engineering plastic. It has better strength than PP and PE, and is often mixed with PC in engineering plastics. For the time being, ABS is listed in engineering plastics.)

Application requirements of main household appliance plastics

Refrigerator

Requirements: sufficient mechanical strength, rigid dimensional stability, creep resistance

Cold storage and freezing room: in addition to the above mechanical property requirements, non-toxic, odorless, low temperature resistant, crazing resistant and edible oil are required in the open sea

Washing machine

Requirements: high heat resistance (100 ℃), good chemical resistance, excellent resistance to detergent, lubricant, grease, etc. and good impact resistance. The general plastic PP (inner barrel cover plate, base turbine, etc.) is used more. The engineering plastics are polyoxymethylene polyacyl and ABS.

Air conditioner

Requirements: rigidity, creep resistance, impact resistance, flame retardancy, vibration resistance, cold resistance, weather resistance, and heat deformation temperature (HDT) ≥ 70 ℃.

The components used are: fan, air inlet window, front control panel, bearing frame, horizontal radiator and rear housing.

Fan: indoor fan: as with 20 ~ 30% glass fiber

Outdoor fan: glass fiber reinforced ABS or as.

Air intake window and front control panel: ABS or hips

Bearing frame and horizontal radiator: glass fiber reinforced ABS

Rear housing: chemical resistant ABS

Refrigerator

Requirements: heat resistance, flame resistance, voltage resistance, corona resistance, arc resistance, good rigidity, impact resistance, dimensional stability, creep resistance, etc;

Plastic raw materials: ABS, polyamide, POM, modified polyphenylene ether, polycarbonate, pet, PBT;

Usage: TV shell, knob, dividing disc, lens, coil framework, transformer control shaft, winding tube, insulating sleeve, etc;

TV shell: flame retardant ABS or hips (ABS has better comprehensive performance than hips) mostly adopt ABS; Flame retardant UL94 V-O grade (abs/pvc alloy is widely used in the United States, and modified polyphenylene oxide is also used in China, but the price is high)

Electric fan

Product: blade cover, shell cover, knob version, etc

Plastic raw materials: ABS as Reinforced PPS, etc

Blade: opaque ABS manufacturing transparent as manufacturing

Vacuum cleaner

Requirements: good rigidity, impact resistance, scratch resistance, good dyeing and gloss, anti-static and avoid dust absorption

Plastic raw materials: polyamide (PA) or reinforced PP is used for the shell (ABS) of the vacuum cleaner, motor support, wheel accessories, etc

Electric iron

Requirements: heat resistance, impact strength and appearance

Plastic raw materials: the shell, handle and sink bottom plate of the electric iron are made of reinforced PP or ABS. The parts near the heating area are required to have high heat resistance and are made of PC PA reinforced PBT.

Microwave oven and rice cooker

Requirements: heat resistance, flame retardancy, rigid dimensional stability.

Plastic materials: the shell adopts ABS, and the handle electric switch knob adopts reinforced PBT and ABS;

The temperature of internal parts shall be as high as 200 ℃. Only glass fiber reinforced PSF Glass Fiber Reinforced PPS polyether ether ketone (PEEK) and liquid crystal polymer (LCP) can meet the requirements.

Radio recorder video recorder

Frame and spindle

Requirements: good impact resistance, dimensional stability, chemical resistance, surface gloss, easy painting and coloring

Plastic raw materials: mostly made of abs/pvc alloy or ABS hips.

Chassis

Requirements: high rigidity, high mechanical strength, excellent wear resistance, dimensional stability and formability

Plastic raw materials: made of Glass Fiber Reinforced PPS or POM

Tape reel

Requirements: good wear resistance, high rigidity, good dimensional stability and formability

Plastic raw material: POM

Internal parts: bearing sleeve, gear flywheel, etc

Requirements: excellent wear resistance, fatigue resistance, impact resistance and dimensional stability

Plastic raw material: POM or PC

Combination sound equipment

Parts and components using engineering plastics: chassis cover trim, plug disc, etc

Chassis and housing

Requirements: high rigidity, impact resistance, dimensional stability and scratch resistance

Plastic material: ABS or as

Trim

Requirements: excellent surface roughness, rigid dimensional stability

Plastic material: ABS as or PC

Plug:

Requirements: impact resistance, rigidity, high dimensional stability, excellent insulation

Plastic raw material: PA PSU (polysulfone)

CD

Requirements: high purity, high transparency and good melt fluidity

Plastic material: PC

Lighting fixtures

Components using engineering plastics: support lampshade lens

Holder and lampshade

Requirements: good heat resistance, rigid impact resistance and dimensional stability

Plastic raw material: PP or ABS

Lens

Requirements: excellent transparency, rigid heat resistance, dimensional stability

Plastic material: as PC
