High-performance engineering plastics play an important role in the automotive industry
The lightweight of plastic makes for a more energy efficient vehicle. It is estimated that every 10% reduction in vehicle weight will result in a 5% to 7% reduction in fuel consumption. Current economic and environmental issues make the gasoline industry a top priority for the gasoline industry. Other advantages of high performance engineering plastics for transportation vehicles include:
Minimal corrosion, allowing longer vehicle life
Free design freedom, allowing advanced creativity and innovation
Flexibility to integrate components
Safe, comfortable and economical
Below are thirteen high performance plastics used in automotive hardware. Although all 13 can be easily used in a single vehicle, only three types of plastics account for about 66% of the total high performance plastic used in automobiles: polypropylene (32%), polyurethane (17%) and PVC (16). %)).
1) Engineering Plastics - Polypropylene (PP)
Applications: Automotive bumpers, chemical tanks, cable insulation, gas cylinders, carpet fibers.
2) Engineering Plastics - Polyurethane (PUR)
Solid polyurethanes are elastomeric materials with excellent physical properties including toughness, flexibility, abrasion resistance and temperature resistance. Polyurethane has a wide range of hardness, from eraser to bowling hard. Other polyurethane properties include extremely high bending life, high load carrying capacity and excellent weatherability, ozone, radiation, oil, gasoline and most solvents.
Applications: Flexible foam seats, foam insulation panels, elastic wheels and tires, automotive suspension bushings, gaskets, electric potting compounds, hard plastic parts.
3) Polyvinyl chloride (PVC)
PVC has good flexibility, flame retardancy, and has good thermal stability, high gloss and low (to no) lead content. Polyvinyl chloride molding compounds can be extruded, injection molded, compression molded, calendered, and blow molded to form a variety of products, depending on the amount and type of plasticizer used, rigid or flexible.
Applications: Automotive dashboards, cable jackets, pipes, doors.
4) Engineering Plastics - ABS
Acrylonitrile butadiene styrene is a copolymer of styrene and acrylonitrile polymerized in the presence of polybutadiene. Styrene gives the plastic a glossy, impervious surface. Butadiene, a rubbery substance provides elasticity even at low temperatures. Various improvements can be made to improve impact resistance, toughness and heat resistance.
Application: Automotive body parts, instrument panels, wheel covers.
5) Engineering Plastics - Polyamide (PA, Nylon 6/6, Nylon 6)
Nylon 6/6 is a universal nylon that can be molded and extruded. Nylon 6/6 has good mechanical properties and wear resistance. It is often used when low cost, high mechanical strength, rigidity and stable materials are required. Nylon is highly absorbent and swells in wet conditions.
Applications: Gears, bushings, cams, bearings, weatherproof coatings.
6) Engineering Plastics - Polystyrene (PS)
Application: device housing, buttons, auto parts, display base.
7) Polyethylene (PE)
Application: car body (glass reinforced plastic), electrical insulation.
8) Engineering Plastics - POM (Polyoxymethylene)
POM has excellent stiffness, stiffness and yield strength. These properties are stable at low temperatures. POM is also highly chemical and fuel resistant.
Application: interior and exterior decoration, fuel system, pinion.
9) Engineering Plastics - Polycarbonate (PC)
Amorphous polycarbonate polymers offer a unique combination of stiffness, hardness and toughness. It has excellent weatherability, creep resistance, impact resistance, optical properties, electrical and thermal properties. Due to its extraordinary impact, it is the material for car bumpers, various helmets and bulletproof glass substitutes.
Application: bumper, headlamp lens.
10) Acrylic acid (PMMA)
Transparent thermoplastics, PMMA is often used as a lightweight or shatterproof glass substitute. It is cheaper than a PC, but it is also easier to scratch and break.
Application: windows, display, screen.
11) Engineering Plastics - PBT (polybutylene terephthalate)
Thermoplastic PBT is used as an insulator in the electrical and electronics industries. It has a high degree of chemical and heat resistance. A flame retardant grade is available.
Application: door handle, bumper, carburetor parts.
12) Engineering Plastics - Polyethylene terephthalate (PET)
Applications: wiper arm and gearbox, headlamp holder, hood, connector housing.
13) Engineering Plastics - ASA (Acrylonitrile Styrene Acrylate)
Similar to ABS, ASA has good toughness and rigidity, good chemical and thermal stability, excellent weatherability, aging and yellowing resistance, and high gloss. Be careful not to burn this material. Can cause toxic fumes.
Applications: enclosures, profiles, interior components and outdoor applications.
