Can POM Tubes be used in automotive applications?
In the dynamic world of automotive engineering, the quest for high - performance, reliable, and cost - effective materials is a constant. Polyoxymethylene (POM), also known as acetal, is a thermoplastic that has been making waves in various industrial sectors. As a POM tube supplier, I am often asked whether POM tubes can be used in automotive applications. In this blog post, I will delve into the properties of POM tubes, their potential uses in the automotive industry, and the associated challenges.
Properties of POM Tubes
POM is a semi - crystalline engineering thermoplastic with several remarkable properties that make it an attractive option for many applications. Firstly, POM has excellent mechanical properties. It has high stiffness, which means it can maintain its shape under load. This is crucial in automotive applications where components are often subjected to significant forces. For example, in suspension systems, parts need to be able to withstand the weight of the vehicle and the forces generated during acceleration, braking, and cornering.
Secondly, POM has a low coefficient of friction. This property makes it ideal for applications where moving parts are involved. In automotive engines, there are numerous moving components such as pistons, gears, and bearings. Using POM tubes in these areas can reduce friction, which in turn leads to less wear and tear, improved efficiency, and lower energy consumption.
Another important property of POM is its high fatigue resistance. Automobile components are often subjected to repeated stress cycles over their lifetime. POM tubes can withstand these cyclic loads without significant degradation, ensuring long - term reliability of the automotive parts.
POM also has good chemical resistance. It can resist many common automotive fluids such as oils, fuels, and coolants. This is essential as automotive components are constantly in contact with these substances. For instance, fuel lines and connectors need to be made of materials that can resist the corrosive effects of gasoline and diesel.
Potential Automotive Applications of POM Tubes
- Fuel System Components
In the fuel system, POM tubes can be used for fuel lines and connectors. Their chemical resistance to fuels makes them a suitable alternative to traditional materials. POM tubes can withstand the pressure and temperature variations in the fuel system, ensuring a reliable supply of fuel to the engine. Additionally, their low coefficient of friction can help in the smooth flow of fuel, improving the overall performance of the engine.

POM tubes can be used in various interior automotive components. For example, they can be used in the construction of seat adjustment mechanisms. The high stiffness and low friction properties of POM ensure smooth and precise movement of the seats. They can also be used in dashboard components, such as the housing for switches and controls. POM's ability to maintain its shape and appearance over time makes it a good choice for these visible interior parts. - Transmission and Gear Systems
In transmission and gear systems, POM tubes can be used for bushings and bearings. The low coefficient of friction and high fatigue resistance of POM make it suitable for these high - stress applications. Using POM in these areas can reduce noise, vibration, and harshness (NVH) levels in the vehicle, providing a more comfortable driving experience. Our POM Roller Wheel can also be adapted for use in some transmission - related applications, offering smooth rotation and durability. - Cooling System
POM tubes can be used in the cooling system of the vehicle. They can be used as connectors for coolant hoses. Their chemical resistance to coolants and ability to withstand the temperature variations in the cooling system make them a reliable choice. This helps in maintaining the proper flow of coolant and preventing overheating of the engine.
Challenges and Considerations
While POM tubes offer many advantages for automotive applications, there are also some challenges that need to be considered. One of the main challenges is the relatively high cost of POM compared to some other plastics. This can increase the overall cost of the automotive components. However, the long - term benefits such as reduced maintenance and improved efficiency may offset the initial cost.


Another challenge is the limited resistance of POM to UV radiation. If POM tubes are used in exterior automotive applications, they may need to be protected from direct sunlight to prevent degradation. This may require additional coatings or protective measures.
POM also has a relatively high moisture absorption rate compared to some other plastics. In humid environments, this can lead to dimensional changes and a decrease in mechanical properties. Therefore, proper design and sealing are required to minimize the impact of moisture on POM tubes in automotive applications.
Conclusion
In conclusion, POM tubes have great potential for use in automotive applications. Their excellent mechanical properties, low coefficient of friction, high fatigue resistance, and chemical resistance make them suitable for a wide range of automotive components. However, the challenges such as cost, UV resistance, and moisture absorption need to be carefully considered.
