See how the five engineering plastics show their magic power in the field of household appliances and automobiles
- Dec 14, 2018 -

Engineering plastics have the characteristics of high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation. It can be used in harsh chemical and physical environment for a long time, and can replace metals as engineering structural materials. With the development of technology, the application of engineering plastics has been expanding, which has been extended to automobile, household appliances, aviation, medical treatment, sports, electronics, construction and other fields. Next, Xiaobao will show you how the five engineering plastics of PA, PC, POM, PPO and PBT / PET show their magic power in the field of household appliances and automobiles.

PA Plastics of Five Engineering Plastics

Polyamide is a kind of engineering plastics with excellent properties, excellent mechanical properties, outstanding corrosion resistance, oil resistance, heat resistance, high modulus and so on. Its heat resistance, modulus size stability and flame retardancy can be significantly improved by strengthening and flame retardant modification. It is widely used in automotive, electronic and electrical industries, electric tools and other industries.

Application of PA plastics in the field of household appliances: Mainly used for electrical parts of unattended appliances.

The application of PA plastics in automotive field: PA has good comprehensive performance. Strength, dimensional stability and other properties have been improved after glass fiber reinforced, and the price is relatively cheap. Therefore, PA plastics have become the ideal choice material for engine peripheral parts. Intake manifold is the most typical application of modified PA in automobiles. In addition, modified nylon is generally used as the preferred material for engine cover, engine decorative cover, cylinder head and other components. In addition to engine components, modified PA can also be used in oil filters, wipers, radiator grilles, etc.

PC Plastics of Five Engineering Plastics

PC series includes toughening, reinforcing, flame retardant and so on. Its flame retardancy and strength can be significantly improved by modification, which makes modified materials widely used in automotive parts, OA products, electronic and electrical products.

Application of PC plastics in the field of household appliances: Modified PC is specially used in household appliances shell because of its high mechanical properties and good appearance. Usually PC/ABS alloys have the advantages of high toughness, stress cracking resistance, heat resistance and high weld strength.

Application of PC plastics in automobile field: Modified PC is mainly used in automobile interior and exterior decoration due to its high mechanical properties and good appearance. PC/ABS alloy and PC/PBT alloy are the most widely used. PC/ABS alloys are also used to manufacture automotive parts such as dashboard peripherals, antifreeze panels, door handles, negative flow panels, brackets, steering column sheaths, decorative panels and air conditioning system accessories. PC/PET alloy can be used to make automobile exhaust port and license plate set. PC/ABS alloy can also be used to make automotive outfits, such as automotive wheel housing, reflector housing, taillight hood, etc. PC/ABS has good formability and can process large automobile parts, such as automobile fender.

POM Plastics of Five Engineering Plastics

Polyformaldehyde is one of the five engineering plastics. It has the advantages of high hardness, wear resistance, creep resistance and chemical corrosion resistance. It is widely used in automotive, electronic and household appliances.

Application of POM plastics in household appliances: such as turbine of washing machine, power wheel, various parts and components of microwave oven, shell, sliding parts, support frame, etc.

Application of POM plastics in automotive field: Modified POM has low wear resistance and strong rigidity, and is very suitable for manufacturing automotive pumps, carburetor components, oil pipelines, power valves, universal joint bearings, motor gears, cranks, handles, dashboards, window lifts, electric switches, seat belt buckles, etc. Manufacturing wear-resistant parts such as sleeves, gears and sliders is the strength of modified POM. These parts have less wear on metals, reduce the amount of lubricating oil, and enhance the service life of components. Therefore, they can widely replace copper, zinc and other metals to produce bearings, gears, pull rods and so on. The automobile parts produced by POM are light in weight, low in noise and simple in forming and assembling, so they are more and more widely used in automobile manufacturing industry.

PBT Plastics of Five Engineering Plastics

Polybutylene terephthalate (PBT) is an excellent engineering material with excellent toughness, fatigue resistance, heat resistance, weather resistance, good electrical properties and low water absorption. Its heat resistance, modulus, dimensional stability and flame retardancy can be significantly improved by strengthening and flame retardant modification. It is widely used in automobile, household appliances and other industries.

Application of PBT plastics in the field of household appliances: Flame-retardant PBT is mainly used in household appliances with flame-retardant requirements.

Application of PBT plastics in automobile field: PBT plastics are widely used in bumper, carburetor assembly, fender, spoiler, spark plug terminal plate, parts of fuel supply system, dashboard, automobile igniter, accelerator and clutch pedal, etc. PBT alloys are also widely used in high-end cars. PBT/PC alloy has good heat resistance, stress cracking resistance, excellent wear resistance, chemical corrosion resistance, high impact strength at low temperature, easy processing and good finishing. It is mainly used in bumper, car bottom plate, panel and motorcycle guard plate of high-grade cars.

PPO Plastics of Five Engineering Plastics

Polyphenyl ether (PPE) has excellent physical and mechanical properties, heat resistance and electrical insulation, low moisture absorption, high strength and good dimensional stability. It is widely used in water-related fields such as kettle cover, valve core, pump, impeller, etc.

Application of PPO plastics in the field of household appliances: heat resistance, stress cracking resistance, mainly used in the kettle cover of electric kettle.

Application of PPO plastics in automotive field: Modified PPO is mainly used in automotive parts with high requirements for heat resistance, flame retardancy, electrical performance, impact performance, dimensional stability and mechanical strength. For example, PPO/PS alloy is suitable for humid, loaded and high electrical insulation requirements, good dimensional stability occasions, suitable for manufacturing automotive wheel cover, headlamp glass slot, taillight housing and other components, also suitable for manufacturing automotive electrical components such as connection box, fuse box, circuit breaker shell. Because of its excellent mechanical properties, dimensional stability, oil resistance, electrical insulation and impact resistance, PPO/PA alloy can be used to make automotive exterior parts, such as large baffles, cushion pads, rear baffles, etc.
