High-Performance Polymers for the Automotive Industry
Also in automotive, materials must meet strict prerequisites to ensure safety, performance and durability in challenging environments.
High-performance polymers, including PEEK, Polyimide, PAI, PEI, PPA, and PBI find use in critical applications due to their unique characteristics.
In various applications in the automotive industry, PEEK actively serves as a high-performance thermoplastic. Here are some examples: PEEK is used in fuel pumps and connectors because it can resist different fuels.
It is also suitable for components of fuel, brake, and transmission systems, including gears and bearings. Other applications include coating metal surfaces, Airconditioning systems, engine management systems, clutch, gearboxes and electronic & sensor systems.
Engine components such as gaskets and seals actively utilize AURUM® TPI due to its ability to withstand high temperature and remain stable during chemical reactions. These gaskets and seals help prevent leaks of liquids and gases. Another application is the Thrust washer. It has sliding properties, chemical resistance, and dimension stability, which helps reduce weight by approximately 60% compared to metal.
Other uses of AURUM in the automotive industry include Seal rings for transmissions, turbocharger abradable seals, turbocharger bearing retainers for high-temperature environments, engine pistons, and bearings.
Polyimide can resist different fuels because of its chemical properties, making it a good material for making fuel system parts. For example, fuel injectors. Also, fluid handling systems, such as tubing & connectors in various automotive applications, can benefit from polyimides' excellent chemical resistance.
On the other hand, materials can retain their high integrity with Celazole® PBI, which is stable at high temperatures and resistant to wear.
It can actively contribute to crafting interior components such as trim and panels
In addition, Celazole® has a high resistance to heat, which makes it suitable for applications that need thermal insulation. For example, it actively produces heat shields and insulating materials that protect sensitive components from high temperatures
Some sensors in car systems need a stable and heat-resistant material to cover them, and PAI is a good choice for this because it does not change shape or size easily and can handle very hot or cold temperatures. This helps the sensors work correctly and independently.
Furthermore, hydraulic seal rings and axial thrust bearings can be made from PAI. and can handle hot or cold temperatures.
On the other hand, PEI is a good material for producing components for automotive lighting systems. It has high transparency and can withstand UV radiation. PEI also has high dimensional stability and can resist wear and abrasion, making it fit for making vehicle sensors and actuators. These components, such as safety and control, are essential for various automotive systems.
Lastly, the high heat deflection (180°C to 250°C) and glass transition (Tg) (100°C to 140°C) temperature properties of PPA make it more suitable for producing automotive components. It is ideal for making parts related to the cooling system, such as thermostat housing, water pump impellers and radiator end tanks.
In addition, PPA can handle temperature changes, which makes it suitable for making fasteners, clips and brackets. It can resist chemicals and high heat, making it fit for components in emission control systems, including part of the exhaust gas recirculation (EGR) systems.
Additionally, they are used for electric motor Bobbin parts, fuel cut-off valves, and LED headlights.
