In home appliances, ABS, ABS/PVC, AS, PC, POM, MPPO, PET, enhanced PBT, PSF and other engineering plastics are more common, why these engineering plastics?
In fact, ABS is not engineering plastics, compared with PP, PE and other good strength, and often with engineering plastics in PC blend alloy, temporarily listed in the engineering plastics ABS.

The components used are fan, air inlet window, front control panel, bearing frame, horizontal radiator and rear housing.
Fan: Indoor fan: 20% to 30% glass fiber AS is used
Outdoor fan: ABS or AS reinforced with glass fiber.
Intake window and front control panel: ABS or HIPS
Bearing frame and horizontal radiator: glass fiber reinforced ABS
Rear housing: ABS resistant to chemicals
Requirements: heat resistance, flame retardant voltage resistance, corona resistance, arc resistance, good rigidity, impact resistance, dimensional stability, creep resistance, etc.
Plastic raw materials: ABS, polyamide, polyformaldehyde, modified polyphenyl ether, polycarbonate, PET, PBT;
Use: TV shell, knob, dial, lens, coil skeleton, transformer control shaft, winding tube, insulation sleeve, etc.;
TV shell: flame retardant ABS or HIPS (ABS comprehensive performance is better than HIPS) using ABS; Flame retardant UL94 V-O grade (ABS/PVC alloy is widely used in the United States, China also uses modified polyphenyl ether, but the price is higher）
Electric fan
